Claim:
A passive lock assembly for use with a door mounted to a door frame and moveable between an open position and a closed position, the passive lock assembly comprising: a housing adapted to be mounted on the door, the housing including a face plate having an active bolt opening; a first bolt extending from the housing and moveable between an extended position, wherein the first bolt is adapted to engage the door frame to lock the door in the closed position, and a retracted position, wherein the first bolt is adapted to retract from the door frame to permit the door to move to the open position; an actuator supported by the housing and operably connected to the first bolt, the actuator being moveable to move the first bolt between the extended position and the retracted position, the actuator having an engagement surface; and a stop member pivotably connected to the housing and pivotable between a first position, wherein the stop member engages the engagement surface of the actuator to obstruct movement of the actuator and prevent movement of the first bolt to the retracted position, and a second position, wherein the stop member does not obstruct movement of the actuator, and wherein the stop member is repositionable from the second position to the first position when contacted by a portion of an active lock assembly extending through the active bolt opening of the face plate.
