Abstract

An alarm system for generating an alarm from a remote location and which utilizes electrically generated codes to access selected functional portions of the alarm system circuitry and which further utilizes a locking transmitter which must be reset after a single use thereof before the transmitter may be re-used, the transmitter resetting being achieved by means accessible only to authorized personnel.

Claims

1. An alarm system comprising:

at least one portable initiator means which is operable to transmit a first coded signal;

said portable initiator means including manually operable actuator means which is operable to actuate said portable initiator means for transmitting said first coded signal;

at least one receiver/retransmitter means operable to be actuated by receiving such a first coded signal and in response to retransmit a second coded signal having a code different from said first coded signal;

receiver means operable to receive said second coded signal;

indicia means associated with said at least one receiver/retransmitter means and operable to provide a local alarm upon actuation of said at least one receiver/retransmitter means and;

said portable initiator means further including locking switch means which is operable to permit locked actuation of said actuator means to thereby limit said transmitting of said first coded signal, said portable initiator means being inoperable until reset by Authorized security personnel.

2. The alarm system as set forth in claim 1 wherein said locking switch means includes a mechanical lock means which is operative in response to a first given actuation of the respective said actuator means to preclude further actuation thereof.

3. The alarm system as set forth in claim 2 wherein said at least one portable initiator means includes electrically operative means which is operable to release said mechanical lock means to permit further actuation of said actuator means.

4. The alarm system as set forth in claim 3 wherein said at least one portable initiator means includes a plurality of initiators which are operable to transmit a respective plurality of said first coded signals which are mutually distinct one from another.

5. The alarm system as set forth in claim 4 wherein said at least one receiver/retransmitter means includes a plurality of receiver/transmitter units each of which is capable of receiving only the said first coded signal of a respective one of said plurality of initiators, each of said plurality of receiver/retransmitter means being operable upon actuation thereof by the respective one of said plurality of initiators to retransmit said second coded signal.

6. The alarm system as set forth in claim 5 additionally including at least one additional receiver/retransmitter means which is operable in response to receipt of said second coded signal to retransmit a third coded signal.

7. The alarm system as set forth in claim 6 wherein said plurality of receiver/retransmitter units and said additional receiver/retransmitter means all include indicia means for local indication of actuation thereof.
