     This application claims priority to U.S. Provisional Application No. 63/060,482, filed Aug. 3, 2020, the entirety of which is hereby incorporated by reference. 
    
    
     FIELD 
     The present disclosure generally relates to a safe or vault door and more particularly to systems for locking and unlocking a safe or vault door. 
     BACKGROUND 
     Vaults and safes are used in a variety of different applications to provide protection and safekeeping of valuable items. Vaults and safes come in a wide variety of sizes such as standalone cabinets to entire rooms within a building, such as a bank. 
     SUMMARY 
     In one aspect, a vault door system for use in a vault comprises a door having opposite interior and exterior sides. The interior side is arranged to face an interior of the vault. A plurality of locking bolts are supported by the door. The locking bolts are movable between a locked position and an unlocked position. In the locked position, the locking bolts protrude from the door so that the locking bolts are positioned to engage a frame of the vault to lock the door in a closed position. In the unlocked position, the locking bolts are retracted relative to the locked position so that the locking bolts are positioned to disengage the frame to permit the door to be moved to an open position. A drive system includes a prime mover and a drive train. The prime mover is configured to actuate the drive train to move the locking bolts between the locked and unlocked positions. An inner handle is at the inner side of the door and is arranged to be accessible from the interior of the vault. The inner handle is operatively coupled to the drive train and is movable between a first position and a second position. In the first position, the drive train operatively couples the prime mover to the plurality of locking bolts so that the prime mover can move the locking bolts between the locked and unlocked positions. In the second position, the drive train does not operatively couple the prime mover to the plurality of locking bolts. 
     In another aspect, a vault door system for use with a vault comprises a door having opposite interior and exterior sides. The interior side is arranged to face an interior of the vault. The exterior side includes an exterior surface arranged to face away from the interior of the vault. A plurality of locking bolts are supported by the door. The locking bolts are movable between a locked position and an unlocked position. In the locked position, the locking bolts protrude from the door so that the locking bolts are positioned to engage a frame of the vault to lock the door in a closed position. In the unlocked position, the locking bolts are retracted relative to the locked position so that the locking bolts are positioned to disengage the frame to permit the door to be moved to an open position. A drive system includes a prime mover and a drive train operatively coupling the prime mover to the locking bolts. The prime mover is configured to actuate the drive train to move the locking bolts between the locked and unlocked positions. An outer handle is supported by the door. The drive train operatively couples the prime mover to the outer handle. The outer handle is movable between a retracted position and an extended position. In the retracted position, the outer handle is arranged with respect to the door to obstruct a user from gripping the outer handle to move the door via the outer handle. In the extended position, the outer handle protrudes outward of the exterior surface of the door such that the outer handle can be grabbed by a user. The prime mover is configured to move the outer handle toward the extended position. 
     Other objects and features of the present disclosure will be in part apparent and in part pointed out herein.

     DETAILED DESCRIPTION 
     Referring to  FIG. 1 , a cabinet-style safe or vault  1  includes a vault body  2  defining an interior in which one or more objects (e.g., valuables, etc.) may be stored. The vault body  2  has a door frame  3  that defines an opening a door system  4  of the vault selectively closes. The door system  4  has an outer side that obstructs intruders or unauthorized persons from entering the interior of the vault  1 . The outer side of the door system  4  can include a user interface for unlocking the door system, such as with a code. The door system  4  has an inner side opposite the outer side that faces the interior protected by the door. It will be appreciated that the vault  1  can include features described in more detail below with respect to vault door system embodiments. 
     Referring to  FIGS. 2 and 3 , one embodiment of a vault door system for use in a safe or a vault of the present disclosure is generally indicated by reference numeral  10 . The vault door system  10  or one or more aspects thereof can be used with generally any type or style of safe or vault, such as the vault  1  shown in  FIG. 1 . In one embodiment, the vault door system  10  is installed in a wall of a building to selectively permit ingress and egress for a vault room of the building. The vault door system  10  includes a frame  12  (such as the frame  3  of the vault  1  in  FIG. 1 ) and a door  14 . The frame  12  defines an opening that is selectively closeable by the door  14 . The door  14  closes the opening in a closed position and permits access to the interior of the vault through the opening in an open position (e.g., does not block the opening). The door  14  has opposite interior and exterior sides  16 ,  18 . The interior side  16  faces (e.g., is arranged to face) the interior of the vault. The interior side  16  includes an interior surface that faces the interior of the vault. The exterior side  18  obstructs intruders or unauthorized persons from entering the interior of the vault. The exterior side  18  includes an exterior surface  20  arranged to face away from the interior of the vault. One or more hinges  22  may connect the door  14  to the frame  12 . 
     The vault door system  10  includes a plurality of locking bolts  24  (broadly, at least one) supported by the door  14 . In the illustrated embodiment, the vault door system  10  includes five locking bolts  24 , although more or fewer locking bolts are within the scope of the present disclosure. The locking bolts  24  are generally disposed within openings in the door ( FIG. 9 ). The locking bolts  24  are arranged along a perimeter of the door  14 , such as along a side edge margin thereof as illustrated. In other embodiments, the locking bolts may be arranged along other edges (e.g., top, bottom, left side, right side) of the door. The locking bolts  24  are movable between a locked position ( FIGS. 3, 7 and 10 ) and an unlocked position ( FIG. 9 ). In the locked position, the locking bolts  24  protrude from the door  14  so that the locking bolts are positioned to engage the frame  12  ( FIG. 7 ) of the vault to lock the door in the closed position. As shown in  FIG. 7 , when the door  14  is in closed position and the locking bolts  24  are in the locked position, the locking bolts engage the frame to inhibit the door  14  from being moved to the open position. In the unlocked position, the locking bolts  24  are generally retracted into the door  14  so that the locking bolts are positioned to disengage the frame  12  to permit the door to be moved to the open position. The locking bolts  24  may be completely retracted within the door  14  in the unlocked position, or otherwise retracted into the door a sufficient distance such that the locking bolts are clear of the restraining geometry of the frame  12  in the unlocked position. Once the frame geometry is no longer obstructing the locking bolts  24 , the door  14  is free to swing about the hinges  22 . In the illustrated embodiment, the vault door system  10  also includes a plurality of fixed bolts  26  supported by the door  14 . The fixed bolts  26  are mounted on the hinge side or edge margin of the door  14  and do not move. Accordingly, the fixed bolts  26  are always protruding from the door  14 . Rotating the door  14  about the hinges  22  moves the fixed bolts  26  into engagement and disengagement with the frame  12 . 
     Referring to  FIGS. 3-7 , the vault door system  10  includes a drive system  28 . The drive system  28  is configured to move the locking bolts  24  between the locked and unlocked positions. The drive system  28  includes a prime mover  30  (e.g., electric motor) configured to move the locking bolts between the locked and unlocked positions. In the illustrated embodiment, the prime mover  30  comprises an electric motor, although other configurations of the prime mover are within the scope of the present disclosure. For example, the prime mover may be a hand crank or wheel that is manually turned by a user. The drive system  28  also includes a drive train  32 . Generally, the drive train  32  operatively couples the prime mover  30  to the locking bolts  24 . That is, the prime mover  30  actuates or drives movement of the drive train  32  (broadly, “linkage”) which in turn moves the locking bolts  24  between the locked and unlocked positions. 
     The drive train  32  includes a worm gear  34  configured to be rotated by the prime mover  30 . In the illustrated embodiment, the worm gear  34  is mounted on an output shaft (not shown) of the prime mover  30 . The drive train  32  includes a rack  36  (e.g., a gear rack). Generally, the rack  36  is in meshed engagement with the worm gear  34 . As a result, rotation of the worm gear  34  by the prime mover  30  results in movement (e.g., linear movement) of the rack  36 . The drive train  32  also includes a lock plate  38  (broadly, “link”) and a bolt carrier  40 . The bolt carrier  40  is attached to the locking bolts  24 . For example, each locking bolt  24  may be attached to the bolt carrier  40  with a fastener (e.g., bolt, screw, etc.). The lock plate  38  is operatively coupled to the locking bolts  24 . The lock plate  38  is connected to the bolt carrier  40 . For example, the lock plate  38  may be attached to the bolt carrier  40  with one or more fasteners. Accordingly, the lock plate  38 , bolt carrier  40 , and locking pins  24  are fixed together such that movement of the lock plate results in corresponding movement of the bolt carrier and locking pins. The lock plate  38  is also operatively coupled to the prime mover  30 . Specifically, the lock plate  38  is operatively coupled to the rack  36  such that rotation of the worm gear  34  (by the prime mover  30 ) moves (e.g., linearly moves) the lock plate (and thereby the locking pins  24 ). The lock plate  38  supports the rack  36 . In the illustrated embodiment, the rack  36  is part of a lock block  42 . The lock block  42  is mounted on the lock plate  38 . When locking/unlocking the door  14  with the frame  12 , the prime mover  30  rotates the worm gear  34  which interacts with the rack  36 , converting rotational motion into linear or lateral motion of the rack. This linear movement of the rack  36  (broadly, the lock bock  42 ) causes linear movement of the lock plate  38 , and thus linear movement of the bolt carrier  40  and locking bolts  24 , thereby moving the locking bolts between the locked and unlocked positions. Moreover, the worm gear  34  generally restricts linear motion of the rack  36  (and therefore the lock plate  38 , the bolt carrier  40  and the locking bolts  24 ), inhibiting unintentional movement of the locking bolts between the locked and unlocked positions. In the illustrated embodiment, the lock plate  38  defines one or more channels or slots  44 . A guide or pin  46  of the door  14  is disposed in each slot  44  to guide the linear movement of the lock plate  38 . 
     The vault door system  10  includes an inner handle  48 . The inner handle  48  is supported by the door  14 . The inner handle  48  is at the inner side  16  of the door  14  and is arranged to be accessible from the interior of the vault. The inner handle  48  is configured to allow a user to move the locking pins  24  between the locked and unlocked positions from within the interior of the vault. For example, if the door  14  should become locked while a person is inside the interior of the vault, the person can use the inner handle  48  to unlock the door (e.g., move the locking pins  24  to the unlocked position) and open the door. To move the locking pins  24  between the locked and unlocked positions, the inner handle  48  is configured to operatively disconnect the prime mover  30  (specifically, the worm gear  34 ) from the locking pins. The inner handle  48  is operatively coupled to the drive train  28  (broadly, the inner handle is part of the drive train). Specifically, the inner handle  48  is operatively coupled to the rack  36  (broadly, the lock block  42 ). The inner handle  48  includes a shaft  50 . The lock block  42  (e.g., the rack  36 ) is mounted on the shaft  50  and rotates with the shaft. The shaft  50  extends through and can rotate relative to mounts  52  of the lock plate  38 . 
     The inner handle  48  is moveable (e.g., pivotable) between a default position ( FIGS. 4-6 ) and an override position (not shown). The shaft  50  allows a user to pivot or turn the inner handle  48  between default and override positions, which can be referred to as first and second positions, engaged and disengaged positions, or locked and unlocked positions. In the default position, the drive train  28  operatively couples the prime mover  30  to the locking bolts  24  so that the prime mover can move the locking bolts between the locked and unlocked positions. Specially, in the default position, the rack  36  is in meshed engagement with the worm gear  34 . The inner handle  48  (e.g., shaft  50 ) is positioned such that the lock block  42  engages the worm gear  34 . With the lock block  42  engaged with the worm gear  34 , the lock plate  38  is operatively coupled to the prime mover  30 . As mentioned above, the lock plate  38  is operatively coupled to the rack  36  (broadly, the lock block  42 ) such that rotation of the worm gear  34  linearly moves the lock plate when the inner handle  48  is in the default position. As the lock block  42  is moved by the worm gear  34 , the lock block  42  engages one of the mounts  52  of the lock plate  38 , thereby pushing the lock plate in a linear direction to move the locking pins  24  between the locked and unlocked positions. 
     In the override position, the drive train  38  does not operatively couple the prime mover  30  to the locking bolts  24 . Specifically, in the override position, the rack  36  is disengaged with the worm gear  34 . The inner handle  48  (e.g., shaft  50 ) is positioned such that the lock block  42  does not engage the worm gear. With the lock block  42  clear of the worm gear  34 , the lock plate  38  is free to be manually moved via the inner handle  48  to move the locking pins  24  between the locked and unlocked positions. The inner handle  48  is operatively coupled to the locking bolts  24  so that the inner handle can move the locking bolts between the locked and unlocked positions. Specifically, the inner handle  48  is supported by the lock plate  38  (e.g., the mounts  52  thereof). For instance, the user can slide the inner handle  48  in one direction to move the locking pins  48  toward the locked position and slide the inner handle in the opposite direction to move the locking pins toward the unlocked position. Because the rack  36  is disengaged with the worm gear  34  when the inner handle  48  is in the override position, the inner handle is free to move the locking bolts  24  between the locked and unlocked positions when in the override position. However, because the rack  36  is engaged with the worm gear  34  when the inner handle  48  is in the default position, the inner handle is inhibited from moving the locking bolts  24  between the locked and unlocked positions when in the default position. 
     The inner handle  48  pivots (e.g., rotates) between the locked and unlocked positions. As the inner handle  48  pivots between the locked and unlocked positions, the inner handle rotates the rack  36  (broadly, the lock block  42 ). This moves the rack  36  into and out of engagement with the worm gear  34 . In the illustrated embodiment, the inner handle  48  is configured to be pivoted generally upward (as indicated in  FIG. 6 ) to disengage the lock block  42  from the worm gear  34 . With the lock block  42  disengaged from the worm gear  34 , the user can move (e.g., slide) the lock plate  38  freely, relative to the worm gear, to the left or right to move the locking bolts  24  between the locked and unlocked positions. As is readily apparent, movement of the inner handle  48  conjointly moves the lock block  42 , the lock plate  38 , the bolt carrier  40  and the locking bolts  24 . Accordingly, positioning the inner handle  48  in the override position allows the locking pins  24  to be operated manually (e.g., manual locking and unlocking of the door), in order to manual open the door  14 . Desirably, the inner handle  48  (and by extension the rack  36 ) is automatically returned to the default position when the inner handle is release by the user, thereby reengaging the worm gear  34  with the rack  36 . For example, in the illustrated embodiment, the inner handle  48  is biased toward the default position. The vault door system  10  includes a spring  54  biasing the inner handle  48  toward the default position. In the illustrated embodiment, the spring  54  comprises a torsion spring. The torsion spring is wrapped around the shaft  50  of the inner handle  38  with one engage engaging the lock plate  38  and the other end engaging the shaft. The spring  54  applies a constant biasing force on the inner handle  48 , and thereby the lock block  42 , to return the inner handle to the default position (e.g., to return the rack  36  of the lock block  42  back into engagement with the worm gear  54 ) when the user is not holding the inner handle in the override position (broadly, not pivoting the inner handle away from the default position). 
     Referring to  FIGS. 2 and 8-10 , the vault door system  10  includes an outer handle  56 . The outer handle  56  is supported by the door  14 . The outer handle  56  is at the outer side  18  of the door  14 . The outer handle  56  is configured to allow a user to move the door  14  from the exterior of the door. The outer handle  56  is configured to generally only be used when the user needs to pull the door to rotate the door in one direction about the hinges  22  (either toward the open position or toward the closed position). If the door  14  opens into the vault, as shown in  FIG. 2 , the outer handle  56  is used to move the door to the closed position when the door is in the open position. If the door  14  opens out of the vault, similar to what is shown in  FIG. 1 , the outer handle  56  is used to move the door to the open position when the door is in the closed position. To move the door  14  in the opposite direction, the user can simply push against the exterior surface  20  of the door (either toward the closed position or toward the open position), and does not need to use the outer handle  56 . 
     The outer handle  56  is movable between a retracted position ( FIG. 8 ) and an extended position ( FIGS. 2, 9 and 10 ). The door  14  (e.g., the exterior side  18  thereof) defines a handle recess  58  sized and shaped to receive the outer handle  56  (e.g., at least a portion thereof). Desirably, the handle recess  58  closely conforms to the size and shape of the outer handle  56 . The handle recess  58  extends generally inwardly from the exterior surface  20  of the door  14 . In the retracted position, the outer handle  56  is arranged with respect to the door  14  to obstruct a user from gripping the outer handle to move the door via the outer handle. The outer handle  56  is flush with or retracted (e.g., recessed) into the door  14 . Specifically, the outer handle  56  is disposed within the handle recess  58 . The front or exterior end of the outer handle  56  is either flush with the exterior surface  20  of the door  14  or is recessed inwardly from the exterior surface of the door. Accordingly, a person is not able to grab the outer handle  56  when the outer handle is in the retracted position. This prevent unauthorized persons from accessing the outer handle  56  and moving the door  14  toward the open or closed positions. In the extended position, the outer handle  56  (e.g., at least a portion thereof) is disposed outward or in front of the exterior surface  20  of the door  14  such that the outer handle can be grabbed by a user. This allows the user to pull the outer handle  56  and move the door  14  toward the open or closed position. 
     The drive system  28  is configured to move the outer handle  56  toward the extended position from the retracted position. The drive train  32  operatively couples the prime mover  30  to the outer handle  56 . Specifically, the drive train  32  is operatively coupled to the outer handle  56 . The prime mover  30  is configured to move the outer handle toward the extended position. In the illustrated embodiment, the drive train  32  is operatively coupled to the locking bolts  24  and the outer handle  56  such that the prime mover  30  is moves the locking bolts toward the unlocked position and the outer handle toward the extended position simultaneously. The drive train  32  includes two cams  60  (broadly, at least one cam). The cams  60  are configured to engage the outer handle  56  to move the outer handle toward the extended position (from the retracted position). Specifically, the cams  60  push the outer handle  56  in an outward direction, toward the extended position. The cams  60  are attached to (e.g., mounted on) the bolt carrier  40 . For example, each cam  60  may be attached to the bolt carrier  40  with a fastener (e.g., bolt, screw, etc.). Accordingly, the cams  60  and bolt carrier  40  are fixed together such that the movement of the lock plate  38  results in corresponding movement of the cams  60 . Each cam  60  includes a ramp or cam surface  62  that engages the outer handle  56 . each cam surface  62  is generally planar is an is oriented at an angle, such as about 45 degrees, relative to the direction of movement of the cams  60 . 
     In the illustrated embodiment, the outer handle  56  includes a handle bar  64 . The handle bar  64  is configured to be gripped or grabbed by the user to move the door  14 , when the outer handle  56  is in the extended position. The handle bar  64  is disposed in the handle recess  58  when the outer handle  56  is in the retracted position and is disposed outward of the exterior surface  20  of the door  14  when the outer handle is in the extended position. In the retracted position, the handle bar  64  is flush with or recessed with respect to the exterior surface  20  of the door  14 . In the extended position, the handle bar  64  is spaced from the exterior surface  20  (e.g., a plane defined thereby) such that the user can insert their fingers around the rear of the handle bar to grip and pull the handle bar. The outer handle  56  also includes two protrusions or shafts  66  (broadly, at least one protrusion or shaft) extending from the handle bar  64 . The protrusions  66  extend into the door  14  (e.g., into openings defined thereby). The door  14  supports the protrusions  66  and the protrusions are free to move (e.g., slide) within their openings relative to the door. The protrusions  66  are generally disposed adjacent each end of the handle bar  64 . Mounted on the end of each protrusion  66  (e.g., the end opposite the handle bar  64 ) is a cam cap  68 . Each cam cap  68  is attached to its corresponding protrusion, such as with a fastener (e.g., bolt, screw, etc.). Each cam cap  68  is arranged to be engaged by one of the cams  60 . Each cam cap  68  has an arcuate surface that engages the cam surface  62  of the corresponding cam  60 . 
     In the illustrated embodiment, the outer handle  56  is biased toward the retracted position. The vault door system  10  includes two springs  70  (broadly, at least one spring) biasing the outer handle  56  toward the retracted position. Each spring  70  comprises a compression spring. Each spring  70  generally extends around one of the protrusions  66  with one end engaging the door  14  and the other end engaging the outer handle  56  (specifically, one of the cam caps  68 ). 
     In operation, when the locking bolts  24  are in the locked position (e.g., the bolt carrier  40  is in a locked position), the outer handle  56  is retracted into the handle recess  58 . The springs  70  apply a constant biasing force on the outer handle  56  (in the inward direction), to move (e.g., retract) the outer handle toward the retracted position and hold the outer handle in the retraced position. In the retracted position, the handle bar  54  is received in the exterior surface  20  of the door  14  (e.g., flush with or recessed inboard of the exterior surface) such that the handle bar is not readily available to an unauthorized person or intruder trying to open the door improperly. To move the outer handle  56  to the extending position, the prime mover  30  slides the bolt carrier  40  (as described above), and therefore the cams  60  mounted thereon. As the bolt carrier  40  and cams  60  are moved to their respective unlocked positions, the outer handle  56  is force outward to the extended position ( FIG. 9 ). The cams  60  engage and push the cam caps  68  to move the outer handle  56  toward the extend position. The cam caps  68  (broadly, “cam followers”) ride on the ramp surfaces of the cams  60 . Thus, the outer handle  56  automatically extends outward to the extended position when the door  14  is unlocked (e.g., the locking bolts  24  are moved to the unlocked position). In the extended position, the outer handle  56  is extended outward from the exterior surface  20  of the door  14  so a user can grab the outer handle by extending a portion of their hand (e.g., fingers) behind the handle bar  64 . This facilitates the user pulling the door forward to either the closed position from a rearward open position or the open position from a rearward closed position. 
     The outer handle  56  allows the door  14  to lock even if the handle continues to be held by a user (e.g., the user overcomes the biasing forces of the spring  70  and keeps the outer handle in the extended position). For example, the user may continue to pull the door  14  forward against the frame  12  to keep the door in the closed position as the locking bolts  24  are moved to the locked position to lock the door. Upon pulling the door  14  closed with the outer handle  56 , the locking bolts  24  are allowed to travel back into the locked position without interference due to the user continuing to hold the outer handle in the extended position. In other words, the user continuing to hold the outer handle  56  in the extended position does not interfere with movement of the cams  60  (and therefore the bolt carrier  40  and locking bolts  24 ). This allows the user to keep the door  14  pulled firmly closed using the outer handle  56 , while the vault door system  10  is locked. The user can release the outer handle  56  at any time (after the outer handle has been grabbed by the user in the extended position), permitting the springs  70  to return the outer handle to the retracted position. Thus, the outer handle  56  automatically retracts or returns to the retracted position when released by a user, such as after the door  14  is locked. The outer handle is now once again unavailable for an unauthorized person to grab and try to open the door  14  without properly unlocking the door. 
     Referring to  FIGS. 11 and 12 , the vault door system  10  may include a control system  230 D for controlling the operation of the vault door system  10  (e.g., the prime mover  30 ). The control system  230 D includes a controller  254  (broadly, a computer) for controlling the operation of the vault door system  10 . The controller  254  (e.g., a vault door controller) controls and/or is in communication with different components of the vault door system  10 . The controller  254  comprises a CPU or processor (e.g., a vault door processor). A RAM or memory  256  (broadly, non-transitory computer-readable storage medium) is communicatively coupled to the processor. Generally, the controller  254  controls and operates the various components (e.g., prime mover  30 ) of the vault door system  10 . Broadly, the memory  256  includes (e.g., stores) processor-executable instructions for controlling the operation of the vault door system  10  and the components thereof. The instructions embody one or more functional aspects of the vault door system  10  and the components thereof, as described herein, with the processor executing the instructions to perform said one or more functional aspects. The components of the vault system  10  may be in wired or wireless communication with the controller  254 . Other configurations of the control system  23 D are within the scope of the present disclosure. 
     The control system  230 D includes a user interface  272 . The user interface  272  is disposed on the exterior surface  20  of the door  14 , so that the user interface is accessible from outside the vault. The user interface  272  can be used to unlock the door  14 . The user interface  272  has user input  274  and a display  276 . The user input includes a plurality of actuators (e.g., buttons) including a plurality of number buttons  274 A, such as to enter a code for unlocking the door  24 . The number buttons  274 A are arranged in a circular pattern extending around indicators  276 D,  276 E, which display properties of the vault door system  10 . In the illustrated embodiment, the indicators  276 D,  276 E display current temperature and humidity conditions sensed by integrated temperature sensor  264  and humidity sensor  262 . The temperature sensor  264  and the humidity sensor  262  are arranged to sense the conditions within the interior of the vault. Thus, the user interface  272  (e.g., display  276  thereof) allows a user to know what the conditions of the interior of the vault are like when the door  14  is closed. The display  276  may also include a plurality of other indicators, such as a Wi-Fi connection indicator  276 A, a lower battery indicator  276 B, and a warning indicator  276 C. 
     The control system  230 D can include a lock sensor  267  onboard the door  14  and is connected to the controller  254  to provide a signal of whether the door is locked or unlocked. For example, the lock sensor  267  may be a position sensor arranged to detect location of the locking bolts  24 , the bolt carrier  40 , the lock plate  38 , etc. The control system  230 D may also include a position sensor  266  to detect whether the door is opened or closed. In one embodiment, the position sensor  266  is a hall effect sensor configured to detect the location of the door  14  relative to a magnet  265  on the frame  12  ( FIG. 2 ). In one embodiment, the controller  254  may automatically lock the door  14  (e.g., move the locking pins  24  to the locked position) when the position sensor  266  detects the door is in the closed position. The control system  230 D may also include a current sensor that provides a current signal to the controller  254  to indicate current draw of the vault door system  10  (e.g., of the prime mover  30 ) during door  14  operation. The control system  230 D may also include a motion sensor  270 , such as an accelerometer, to provide a motion signal to the controller  254  to detect motion of the door  14 . The controller  254  can detect faults associated with door  14  operation and indicate such faults via the warning indicator  276 C. For example, if the controller  254  detects current draw via the current sensor out of range when the door  14  is locked or unlocked (e.g., when the locking pins  24  are moved between the locked and unlocked positions), or if the controller detects time to lock/unlock the door is out of range, warning indicator  276 C may be energized. This provides a warning of potential upcoming failure or indicator of actual failure such that the vault door system  10  can be fixed. 
     In one embodiment, the vault door system  10  provides a leveling indication to assist with plumb installation of the vault door system. The motion sensor  270  can also be used to detect the degree of upright orientation of the door  14  to assist with the installation of the vault door system  10 . When the vault door system  10  is positioned at a wall opening for installing the frame  12  in the wall opening, the user interface  272  can be adjusted or changed to an installation mode or a plumb mode. The motion sensor  270  detects the vertical orientation of the vault door system  10  (e.g., the door  14  and the frame  12 ) in the exterior-interior direction (e.g., forward-rearward direction) and the side-to-side direction (e.g., left-right direction). Indication of vertical plumb can be provided by the user interface  272  or via a smart device connected to the control system  230 D, via the communication port  258  and/or cellular port  260 . For example, the communication port  258  can be a Wi-Fi communication port such that the smart device is connected via Wi-Fi. To indicate the plumbness of the vault door system  10 , the exterior-interior attitude can be indicated in degrees relative to the vertical (e.g., E 5 degrees or I 11 degrees) in the location of the temperature indicator  276 D. Side-to-side attitude can be indicated in degrees relative to the vertical (e.g., L 2 degrees or R 6 degrees) in the location of the humidity indicator  276 E. As the vault door system  10  is tiled to approach vertical, the attitude numbers approach zero and show zero when vertical. In another embodiment, to indicate the plumbness of the vault door system  10 , the number indicators  274 A of number buttons are illuminated based on the attitude of the vault door system. For example, when tilted severely forward and right, only indicator number 4 or 5 is illuminated. As the door is tilted to approach plumb, indicator numbers 3, 4, 5 and 6 are illuminated. When the door is fully plumb or vertical, all the number indicators  274 A are illuminated. In another embodiment, the smart device connected to the control system  230 D via the communication port  258 . An application on the smart device displays the attitude of the vault door system  10  relative to the vertical to assist the user in orienting the vault door system to achieve vertical plumb. In these embodiments, the attitude indications are provided in real time so the installer can reference the indicators to know whether to move/tilt the vault door system  10  in a particular direction to achieve vertical plumb. 
     The frame  12  of the vault door system  10  may include inner and outer electrical power ports for powering the components of the vault door system, such as the controller  254  and the prime mover  30 . For example, a first electrical power port may be provided at the lower, front side of the frame  12  and a second electrical power port may be provided at the lower, rear side of the frame. The vault door system  10  may be connected to AC and/or DC power. For example, the vault door system  10  can include an AC power cord with an electrical outlet plug that can be used for connecting electrical power to the first or second electrical power ports. Alternatively, or in addition to, a DC power cord including first and second electrical contacts can be connected to terminals of a large capacity DC power source (e.g., a battery, a DC power inverter, solar panels, etc.) and connected to the first or second electrical power ports. The vault door system  10  may include an internal battery backup. Internal batteries mounted in the door  14  can be automatically charged when connected to power at the first or second electrical power ports. When a loss of power is detected (such as during a grid failure such that the first and second electrical power ports are not receiving power), the controller  254  can automatically change over to the internal battery power source. This modular power source allows AC and/or DC power to be connected to run the vault door system  10  uninterrupted and to have an internal battery backup in the event of a power loss.
