Description:
TECHNICAL FIELD 
     The invention relates to a security system which activates an alarm in response to an intrusion, and more specifically, to a completely remotely controlled security alarm system. 
     BACKGROUND OF THE INVENTION 
     Many security systems use the following: door and window units for sensing an intrusion by the opening thereof, a main console to which the door and window units are wired in connection therewith, and either key or number pad arming and disarming units on the inside of the door or window. The cost and difficulty involved in installation of such a system is expensive and complex. Therefore, security systems have used remote door and window units which transmit radio signals upon the opening thereof. A remote console receives radio signals and will turn an alarm on if the console is in the armed state. 
     One such security system is disclosed in U.S. Pat. No. 3,833,895 granted Sept. 3, 1974 in the name of Dennis E. Fecteau. This patent discloses magnetic normally-closed door or window unit which transmits a coded radio signal if a switch in the unit is opened. The master unit or console includes an arming or power switch to set the device in the armed or alarm mode. When in the armed mode, if the master unit receives a coded signal from a door or window unit, an alarm will be sounded. The door unit includes a button which is to be depressed when a person exits a door, causing a delay in the triggering of the console. This patent also discloses a hand held unit which includes two buttons. A first button may be depressed to indicate that a prior intrusion has occurred by not sounding a beep. When this button is depressed, the console is disabled until resetting it by turning the power off and on. The second button is a panic button which immediately turns the alarm on when depressed. A problem with this type of device is a delay in the system when a person is exiting the house. Additionally, when the intrusion button is depressed, the system is disabled until manual reset on the console. Another problem with this type of system is that the system can not be armed remotely. Also, an intruder may easily find the console by the alarm sound and cut the wires from the console to the alarm. 
     Another type of security system is related to the remote control of a garage door and the securing of a house. Such a system is disclosed in U.S. Pat No. 4,464,651 issued Aug. 7, 1984 in the name of Dean C. Duhame. This patent discloses a radio transmitter unit which will close the garage door and arm the system by locking the door. The transmitted signals between the transmitter and the central control unit coded and selected by the consumer through switches. The transmitter unit includes a secure button which is a toggle between arming and disarming. Portal switches from doors and windows may be interconnected directly to the security alarm. A problem with this type of system is that the user may forget the state of the security system, and the system is integrally related to garage door systems. Accidental depression of the buttons may occur disabling or enabling the system without the consumers knowledge. Additionally, the same problem arises with the integral console and alarm as in the previous prior art. 
     SUMMARY OF INVENTION AND ADVANTAGES 
     The invention is a security assembly and a method for indicating when a closable entrance has been opened. The assembly includes entrance monitoring means for producing an intrusion coded signal when the entrance has been opened, and a console means for receiving the intrusion coded signal producing an alarm radio signal indicating the intrusion. The system is characterized by alarm means remote from the console means for receiving the alarm radio signal to produce an audible signal. 
     The invention also includes a console means having an armed mode and disarmed mode for receiving the intrusion signal and indicating when the entrance has been opened when the console means is in the armed mode. A remote control means sets the console means in the armed or disarmed mode. The remote control means includes arm button means to be manually depressed to set the console means in the armed mode by transmitting an arming coded radio signal and disarm button means to be manually depressed to set the console means in the disarmed mode by transmitting a disarming coded radio signal. Also included is a protective cover means for sliding across one of said buttons exposing the other for depression and sliding partially over both of said buttons to prevent accidental depression of said buttons. 
     Advantages of this invention are that the console and the alarm means are not wired together which will prevent deactivation thereof by an intruder, and the installment procedures are easier. Also, by including separate arm and disarm buttons, a user may always be sure which state the security device has left in by double checking by depressing the disarm button. Additionally, the protective cover on the remote control means will insure against accidental activation or deactivation of the alarm system.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     A security assembly for indicating when a closable entrance has been opened is generally shown at 10 in FIG. 1. The assembly 10 includes entrance monitoring means 12 for producing an intrusion coded signal when the entrance has been opened or intruded, console means 14 for receiving the intrusion signal and producing an alarm radio signal indicating intrusion, alarm means 16 remote from the console means 14 for receiving the alarm radio signal to produce an alarm or indication signal, and remote control means 18 for setting the console means 14 in an armed and disarmed mode. The entrance monitoring means 12, the console means 14, the alarm means 16, and the remote control means 18 are all remotely controllable with respect to one another by transmitting and receiving radio signals producing a completely wireless security alarm assembly 10. Therefore, installation of the subject invention may be accomplished by the consumer without disturbing or re-constructing the premises to be secured. 
     In general, the console means 14 is the main controller of the assembly 10 which receives and/or transmits coded radio signals to each of the other means. The alarm means 16 produces an audible piercing sound in response to receiving coded radio signals from the console means 14. The remote control means 18 is a radio signal transmitter for arming and disarming the console means 14 from a remote location. The entrance monitoring means 12 is a normally closed switch between a wall and a door or window which transmits coded radio signals when opened. 
     The console means 14 has an armed mode and disarmed mode for receiving the intrusion coded signals from the entrance monitoring means 12 indicating that an entrance has been opened or intruded when the console means 14 is in the armed mode. The console means 14 may be placed in the armed and disarmed modes either remotely by the remote control means 18 or by the console means 14 itself, as explained subsequently. When the console means 14 is in the armed mode, any received intrusion coded signal from the entrance monitoring means 12 will command the console means 14 to transmit an alarm radio signal to the alarm means 16 to produce an indication signal, or more specifically an audible signal. Upon receipt of an intrusion coded signal in the disarmed mode, the console means 14 will not transmit a alarm radio signal to the alarm means 16. 
     To arm and disarm the console means 14, the remote control means 18 includes arm button means 20 to be manually depressed to set the console means 14 in the armed mode by transmitting an arming coded radio signal. A disarm button means 22 is included to be manually depressed to set the console means 14 in the disarmed mode by transmitting a disarming coded radio signal. If the arm button means 20 or disarm button means 22 is depressed for a predetermined time, such as 2 seconds, the console means 14 will immediately turn on the alarm means 16 for panic operation, as will be described subsequently. For normal operation of the arm 20 or disarm 22 button means, the buttons 20, 22 need be momentarily depressed, i.e. 1/2 second. If the arm button means 20 is depressed more than once in a 5 second period, a long tone is produced by the alarm means 16. 
     The console means 14 includes arming switch means 24 for setting the assembly 10 in the armed mode. Therefore, the assembly 10 may either be set in the armed mode by the arm button means 20 on the remote control means 18 or by the arming switch means 24 on the console means 14. Also included is test switch means 26 for setting the console means 14 in a test mode to test the entrance monitoring means 12 for proper operation, as will be described subsequently. A panic switch means 28 is included for immediately turning on the remote alarm means 16 in cases of emergency. Also included is disarming switch means 30 for setting the assembly 10 in the disarmed mode, and for turning off the audible signal of the alarm means 16, and for exiting the test mode, and for turning off an intrusion indicator, as will be subsequently described. 
     The console means 14 includes an armed indicator means 32 for audibly indicating that the console means 14 has been set in the armed mode by the remote control means 18. There is an armed LED 34 on the console means 14 for visibly indicating that the assembly 10 is in the armed mode. When the assembly 10 is set in the armed mode by the remote control means 18, a short beep will be produced by the alarm means 16 indicating this setting. If a short beep is not produced upon &#34;arming&#34;, this will indicate that the assembly 10 is not armed or properly working. The short beep is produced by a beep generator 33 producing a short alarm radio signal. The console means 14 also includes an intrusion indicating means 36 for indicating that an entrance monitoring means 12 has previously opened in the armed mode, or in other words that the alarm means 16 has sounded. The intrusion indicating means 36 audibly indicates when the entrance monitoring means 12 has been previously opened. This is accomplished by depressing the disarm button means 22 of the remote control means 18 which will sound a beep from the alarm means 16. The beep generator 33 is responsive to the intrusion indicating means 36 to produce the alarm radio signal. Also included is an intrusion visual indicator 38 on the console means 14 which can only be disarmed or turned off by the disarming switch means 30 of the console means 14. Therefore, if an intrusion has occurred between arming and returning to the secured area and the alarm means 16 is not still sounding, a beep will be produced when the console means 14 is disarmed by the remote control means 18. This may indicate that there may be reason to believe an intruder is still on the premises. During normal disarming, no sound or beep is produced. 
     When the console means 14 is in the armed mode, and an intrusion occurs sensed by the entrance monitoring means 12 or through panic operation, the console means 14 sends the alarm radio signal to the alarm means 16 for sounding the alarm. The console means 14 includes timer means 40 for transmitting the alarm radio signal for a predetermined time. Upon intrusion, a continuous sound is produced by the alarm means 16 in absence of the disarming. The alarm means 16 will sound for a predetermined time, such as five minutes, at which time the console means 14 stops sending the alarm radio signal which effectively turns off the alarm means 16. The sounding of the alarm means 16 may also be disabled by the disarm button means 22 of the remote control means 18 or the disarming switch means 30 of the console means 14 prior to the timer means 40 which turns off the alarm means 16 after a 3 or 4 second delay. 
     The operation of the test mode which is set by depressing the test switch means 26 on the console means 14 is as follows. When the test switch means 26 is depressed, a test latch 27 is set indicative of the test mode. When in the test mode, a test indicator means 42 visually indicates that the test switch means 26 has been depressed and the console means 14 is in the test mode. Each entrance monitoring means 12 may be checked individually by opening each door or window which will sound a short beep by the alarm means 16 indicating that the system works properly. The alarm radio signal representing a beep is sounded by a test beep generator 29. When in the test mode, a beep is not sounded when depressing the arming switch means 24 to protect against the situation where a consumer leaves the house forgetting the system is in the test mode. In this situation, no beep is sounded in attempting to arm the system 10 so that the consumer will be alerted that the system 10 has not been armed and may still be in the test mode. Recalling, arming the system by the arm button means 20 will produce a short beep by the alarm means 16 indicating that the console means 14 has been set in the armed mode. The console means 14 is removed from the test mode by depressing the disarming switch means 30. 
     The coded radio signals transmitted by the console means 14, remote control means 18, and the entrance monitoring means 12, and the coded radio signals received by the alarm means 16 and console means 14 may be any number bit coded signals. In the preferred embodiment, a nine bit coded signal is chosen. The consumer may choose the nine bit code simply by cutting jumpers or using dip switches to produce the code in all the entrance monitoring means 12, remote control means 18, console means 14 and alarm means 16. The nine bit coded signals from the remote control means 18 and the entrance monitoring means 12 are compared within the console means 14 for proper detection and activation of the alarm means 16. The actual transmitted code is an 18 pulse code which is detected as pairs so that there is only 9 actual inputs and outputs. The ninth pulse in the assembly 10 is not user-selectable. The nine bit coding is used for security purposes; the nine bit code has a high probability of receiving a correct signal and a low probability of receiving a wrong signal. Additionally, one system 10 will only activate its own components 12, 14, 16, 18 without interfering with systems of other consumers or different locations. Typical range for the radio coded signals is 75-100 ft., which may be altered by the circuitry. 
     The entrance monitoring means 12 may be attached to any door and adjacent molding strip or wall, or to any window and adjacent molding strip or wall, or some other type of movable object and stationary object to be monitored. Any number of entrances may be monitored by using a plurality of entrance monitoring means 12. As illustrated in Fig. 1, the entrance monitoring means 12 uses a magnetic switch 44, 45 and a battery 46 to detect intrusion. The intrusion coded signal, which is coded nine bit radio signal, is sent to the console means 14 each time the switch 44 is pulled away from the stationary magnet 45 by intrusion or the opening thereof. The entrance monitoring means 12 is a normally closed system. This normally closed switch conserves battery life because a half second signal is sent only when a door or window is opened. This signal is only sent upon the opening of the switch 44, such that if the door or window is left open, the signal will not be continuously transmitted therefor conserving battery life. When the console means 14 receives this intrusion coded signal after having been armed, it indicates intrusion by the intrusion LED 38 and instantly signals the alarm means 16 to activate. Multiple monitoring means transmitters 12 may be used. The intrusion coded signal is sent when any of the sensor switches 44 is opened. The actual circuitry of the entrance monitoring means 12 is shown in FIG. 2 and includes the battery 46 and the magnetic switch 44 which shorts the input signal through a first resistor R1 to an entrance encoder chip 48 when the switch 44 is closed. When the switch 44 is opened, a transistor Q1 pulls the input pin 14 of the entrance encoder chip 48 to ground and the entrance encoder chip 48 transmits through a radio transmitter circuit 49 the intrusion coded signal which is received by the console means 14. An R-C time constant comprising first capacitor C1 and resistive divider R2, R3, holds the transistor Q1 in this state until the intrusion coded signal is completely transmitted. The entrance monitoring means 12 includes a series of jumpers J1-J7 connected to the entrance encoder chip 48 which are to be cut by the consumer to determine the coding. Any combination may be cut, but this first coded combination must be mirrored at the console means 14. The coded inputs of the entrance encoder chip 48 are on pins 1-7, 9, 10, where pin 5 is set high and pin 10 is set low. External timing of the chip 48 is determined by resistor R4 connected to pin 11 and connected to resistor R5 to pin 13, and capacitor C2 connected to resistors R4, R5 and pin 12. Pin 16 is held high and pin 8 is held low. The output signal is at pin 15 to the transmitter circuit 49. 
     The alarm means 16 may solely produce an audible signal and/or be connected to transmit an emergency signal over telephone lines to police or the like. The console means 14 may also be adapted to transmit emergency signal over telephone lines to police or the like. There may be multiple alarms 16 which are coded the same. As illustrated in FIG. 5, the alarm means 16 includes alarm receiver means 50 for receiving and detecting the alarm radio signal producing an alarm signal. The alarm receiver means 50 includes a power jack 52 to be connected to the wall voltage or standard household outlet. The power lead 52 can be used for an antenna. If the alarm means 16 is to be powered by battery only, an antenna may be plugged into the power jack 52. An alarm amplifier means 54 amplifies the alarm signal producing an amplified alarm signal. An alarm limiter means 56 receives the amplified alarm signal and limits the magnitude of the amplified alarm signal producing an alarm limited signal. An alarm decoder means 58 receives the alarm limited signal and decodes it to produces a pulse signal. The alarm decoder means 58 includes switches SW1-SW8 to be set to the consumer selector combination, this second combination code must be the same combination as that on the console means 14. The eighth bit of the code is inverted by the console means 14 and the alarm means 16 detects the eighth inverted bit. The inverting of the bit prevents detection and activation of the alarm means 16 by the remote control means 18. A storage means 60, in the form of a capacitor C5, receives a pulse signal and holds its magnitude above a predetermined limit. A trigger means 62 produces a control signal when the storage means 60 is above the predetermined limit. First 64 and second 66 frequency oscillator circuits produce a dual tone frequency signal in response to the control signal. An audible means 68 converts the dual tone frequency signal into an indication signal or audible signal. The alarm means 16 includes power back-up means 70 to power the alarm means 16 in case of power failure to the secured premises in the wall outlet 52. The power back-up means 70 includes batteries 72. The alarm receiver means 50 includes the power jack/antenna 52 received by a first inductors L1 and second L2. A capacitor C6 is connected between inductors L1 and L2. A capacitor C7 is connected to the power jack 52 and the base of a transistor Q3 and to a resistor R12 to ground. The inductors L1, L2 and capacitors C6, C7 act as filters. The inductor L2 is connected to resistor R10 to ground, and to a zener diode D3 and a diode D4. A transistor Q2 has its collector connected to diode D4 and its base connected to zener diode D3. A resistor R11 is connected to the base of transistor Q2 and to the series batteries 72 used as backup. A voltage regulator 75 is connected to the collector of transistor Q2 and to a capacitor C8 to ground. The d.c. power of voltage regulator 75 is applied to balance the circuitry via L1, L2. The radio coded signal on d.c. power leads is applied to the base of transistor Q3 via capacitors C6, C7 with the voltage regulator 71 on across resistor R10, the transistor Q2 is off. With the voltage regulator 75 off, transistor Q2 is on with the batteries 70 supplying power. The emitter of transistor Q3 is connected to capacitor C9 to ground and resistor R13 to ground. A coil L3 is connected between the collector and the emitter via capacitor C10. A resistor R14 is connected to the base to capacitor C10, and resistor R15 is connected to the coil L3 and power.

The base of the transistor Q4 is connected to resistor R17, and to a parallel capacitor C14 and resistor R18 tapping the second coil L3 producing the alarm signal. The alarm amplifier means 54 includes three resistors R19, R20, R21 receiving the alarm signal: first resistor R19 connected to power, second resistor R20 connected to the inverting input, and third resistor R21 connected to noninverting input of an operational amplifier 55. A first capacitor C15 is connected to the non-inverting input and ground, and a second capacitor C16 is connected between the input terminals of op-amp 55. A feedback resistor R22 is connected to the inverting terminal, the output of the op-amp 55 producing the amplified alarm signal. The alarm limiter means 56 receives the amplified alarm signal and includes an op-amp 57 directly receiving the amplified alarm signal at its non-inverting input, and through resistor R23 to the inverting input. A second resistor R24 is connected to the inverting input power and a capacitor C17 is connected to the inverting input and ground. The output of the opamp 57 produces the alarm limited signal which is received by the alarm decoder means 58 at pin 9. The switches SWl-SW8 are connected to pins 1-5, 13-15. Switch 8 is connected through an inverting circuit to pin 13, which comprises: a resistor R25 connected to the switch and to power, and a transistor Q5 with its emitter grounded and its base connected to SW8 and resistor R25 and the collector connected to pin 13. Pin 6 is connected to timing circuit comprising resistor R26 also connected to pin 7 which is connected to capacitor C18 to ground. Pin 10 is connected to parallel resistor R27 and capacitor C19. The output on pin 11 is isolated by diode D5 which produces the pulse signal. The pulse signal is received by the storage means 60 which includes a resistor R28 connected to the capacitor C5 to ground, and a resistor R29 connected to capacitor C5 and ground. The trigger means 62 includes an op-amp 63 which receives the storage means on its inverting terminal. The noninverting terminal is connected to a voltage divider comprising resistor R30 connected to power and resistor R31 connected to ground, and including a feedback resistor R32. The trigger means 62 is configured as a Schmitt trigger. The output of the op-amp 63 is fed through a voltage divider circuit comprising resistor R33 receiving the output of the op-amp 63 and connected to resistor R34 which is connected to power. Resistor R33 produces the control signal which is received by the first 64 and second 66 frequency oscillator circuit. The first frequency oscillator circuit 64 includes an op-amp 65 which receives the control signal at its noninverting input, and includes a feedback resistor R110 connected to the noninverting input. A capacitor C6 is connected to the inverting input and ground, and the feedback resistor R111 is connected to the capacitor C6 and the output op-amp 65. The second frequency oscillator circuit 66 includes two NAND gates 67, 69. The control signal is fed through a resistor R113 to a reverse bias diode D6 to one of the inputs of the NAND gate 67 wherein the other input is held high. A resistor R114 is connected to the diode D6 which is connected to the output of NAND gate 69. A capacitor C7 is connected between resistor R114 and the output of NAND gate 67, which is connected to a reverse diode D7 to resistor R112 to the control signal.

The output of the first NAND gate 71 is connected to resistor R116 which is connected to the base of transistor Q6 having its emitter connected to ground and the output of the second NAND gate 73 is connected through resistor R117 to a second transistor Q7 having its emitter grounded. The collectors of both transistor Q6, Q7 drive two coils L5, L6 which causes oscillation of ceramic disks or transducers X1-X4. The ceramic disks used are made by MuRata model number 7BB-35-3AO, but any transducer may be used. A capacitor C8 taps the center of coils L5 and L6 connecting to ground. 
     As previously stated, the remote control means 18 includes arm 20 and disarm 22 button means. By using the remote control means 18, there are no delays in the system for exiting or entering the secured premises. As indicated in FIG. 3, also included is a remote control encoder means 74 responsive to the arm 20 and disarm 22 button means. The remote control encoder means 74 includes switches S1-S8 for selecting the coding of the transmitted radio signal. As previously stated, this second coding combination is consumer selected and should be the same combination as the console means 14 and the alarm means 16. An R-C time constant circuit comprising resistor R6 and capacitor C3, allows a battery 76 to supply power to the remote control means 18 in order to transmit the full length of arming and disarming coded radio signals. The battery 76 is connected in series with a transmitting indication means which is an LED 78 which is connected to the resistor R6. The capacitor C3 is connected to the battery 76 and resistor R6. A resistor R7 is connected to the RC time constant circuit R6, C3 and to pin 10 of the encoder 74. A reversed biased diode D1 is connected to the RC time constant circuit R6, C3 and to the disarm button means 22, which is connected to the battery 76. A forward biased diode D2 is connected to the arm button means and pin 14, and the reversed biased diode D1, the arm button means 20 connected to the battery 76. When the arm button means 20 is depressed, pin 14 of the remote control encoder 74 means is held low and pin 10 is pulled high. The transmitting LED 78 is illuminated when either of the buttons 20, 22 is depressed and a coded radio signal is transmitted. When the disarm button means 22 is depressed, pin 14 is held low as is pin 10 of the remote control encoder means 74. Therefore, pin 10 is the ninth data bit in the transmitted coded signals which distinguishes the arming coded radio signal and the disarming coded radio signal. A resistor R8 is connected to pin 13 of the encoder 74 and to a resistor R9 to pin 11, and to a capacitor C4 and pin 12. Pin 16 is held high and pin 8 is grounded. Pins 1-7, 9 are connected to the switches S1-S8. Pin 15 of the encoder 74 is the coded radio signal output to the standard transmitter circuit 49. In the transmitter circuit 49, resistor R103 is replaced by a coil L101. 
     The console means 14 includes console receiver means 80 for receiving the coded radio signals from the remote control means 18 and the entrance monitoring means 12 to produce a detected signal. An audio amplifier means 82 amplifies the detected signal producing an amplified signal. A limiter means 84 limits the magnitude of the amplified signal producing a coded signal. The console means 14 includes an entrance monitor decoder means 86 for receiving and decoding the coded signal producing an intrusion signal when the entrance monitoring means 12 has produced an intrusion coded signal indicating that the entrance has been opened. The entrance monitor decoder means 86 includes a series of jumpers JP1-7 to be cut in the same first combination code as each of the entrance monitoring means 12. The armed indicator means 32 includes a controller decoder means 88 for receiving and decoding the arming coded radio signal and the disarming coded radio signal to produce a mode signal representative of the mode the console means 14 is to be set. The controller decoder means 88 includes code switches SS1-8 to be set in the same second combination code as the remote control means 18 and alarm means 16. The console means 14 also includes alarm encoder means 90 for encoding and producing a coded alarm signal in response to the timer means 40 and the beep generator 33 and the test beep generator 29. The coding of the alarm signal is determined by the switch settings SS1-SS8 It should be realized that any switches, jumpers or the like may be used to select the coding. In the alarm encoder means 90, the eighth bit is inverted as in the alarm means 16 and explained prior. An alarm transmitter means 49 receives the coded alarm signal and transmits it to the alarm means 16 for activation thereof. The console means 14 includes armed flip flop means 94 for storing the mode signal and the arming switch means 24 and the disarming switch means 30 for setting the console means 14 in the armed mode and the disarmed mode by producing an armed signal representative of the mode. An alarm flip-flop means 96 receives the intrusion signal and the armed signal to initiate the timer means 40. The console means 14 includes panic means 98 for receiving an expanded coded radio signal from the remote means or the panic switch means 28. The test beep generator 29 is responsive to the panic means 98 and to the panic switch means 28 to produce an alarm radio signal to produce a beep, The console means 14 includes power indication means 100 for visually indicating when power is being supplied to the console means 14 by a continuous indication and by a chopped indication when the battery back-up 102 is being used. 
     The console receiver means 80 includes an antenna 79 receiving coded radio signals from the entrance monitoring means 12 and the remote control means 18 and through a capacitor C22 and to a resistor R35 to ground. The transistor Q8 connected through has its base connected to the capacitor C22 and to the resistor R35. The emitter of the transistor Q8 is connected to a second resistor R36 and ground, a second capacitor C23 and ground, and a third capacitor C24. A third resistor R37 is connected to the first capacitor C22 and to the third capacitor C24. A first coil L7 is connected to the collector of the transistor Q8 and to the third capacitor C24.
