Abstract

An alarm system is provided including a plurality of remote units each having a fire or burglar alarm for generating an activation signal. A transmitter is situated within the housing for transmitting a signal via free space upon the receipt of the activation signal. Next provided is a central dispatch station including a radio receiver for receiving the signal from the transmitter of at least one of the remote units for dispatching emergency personnel to the at least one of the remote units.

Claims

1. An alarm system comprising, in combination:

a plurality of remote units each including;

a housing having a rectangular configuration with a rear face, a peripheral side wall coupled to a periphery of the rear face and extending forwardly therefrom for defining an interior space and an open front, and a partial front face coupled to a top face of the peripheral side wall and extending downwardly therefrom, the housing further including an L-shaped hammer releasably mounted on a side face of the periphery of the housing via a U-shaped bracket for breaking a plate of glass mounted over the open front of the housing,

an extinguisher assembly including a fire hose situated within the interior space of the housing and connected to a water source for expelling water when removed from the housing, a fire extinguisher situated within the housing for dispensing a fire extinguishing material when removed and a removal indicating switch connected to the fire hose and fire extinguisher for transmitting an activation signal upon the removal of either,

a smoke detector mounted on the top face of periphery of the housing for generating the activation signal only upon the detection of smoke,

a first tape player mounted within the housing and connected to the removal indicating switch of the extinguisher assembly for generating a message indicating the presence of a fire and a location of the housing only upon the receipt of the activation signal,

a second tape player mounted within the housing for generating a message indicating the tripping of a burglar alarm near the housing and the location of the housing only upon the tripping of the burglar alarm,

a radio transmitter situated within the housing and connected to the first tape player, the second tape player, and a microphone mounted on the partial front face of the housing for transmitting at least one of the messages and audible distress signals from the microphone upon the receipt thereof,

a location transmitter situated within the housing and connected to the removal indicating switch of the extinguisher assembly for transmitting a code representative of the location of the housing only upon the receipt of the activation signal,

a loud speaker mounted on the partial front face of the housing and connected to the first tape player and second tape player for emitting at least one of the messages locally upon the receipt thereof, and

a radio receiver situated within the housing and connected to the loud speaker for receiving messages via free space and emitting the same locally;

a public address system with a plurality of loud speakers connected to a radio receiver for receiving the messages and audible distress signals of the remote units and emitting the same from each of the loud speakers of the public address system upon the receipt thereof;

a central dispatch station including a radio receiver for receiving the code from the location transmitter of at least one of the remote units, a zone indicating panel for providing visual indication of the location of the housing and a dialer for dialing emergency personnel and providing the same with the location of at least one of the remote units for dispatching the emergency personnel to said location; and

a protective helmet adapted to be worn by at least one of the emergency personnel, the protective helmet having a transceiver mounted therein with a speaker for receiving the messages and audible distress signals upon the receipt thereof via free space and a microphone for transmitting audible instruction signals to the radio receiver of at least one of the remote units.

2. An alarm system comprising:

a plurality of remote units each including;

a housing,

indicating means situated within the housing for generating an activation signal, and

a transmitter situated within the housing for transmitting a signal via free space upon the receipt of the activation signal; and

a central dispatch station including a radio receiver for receiving the signal from the transmitter of at least one of the remote units for dispatching emergency personnel to the at least one of the remote units;

wherein the indicating means includes a removal indication switch which senses the removal of a fire hose situated in the housing situated in the housing with the fire hose.

3. An alarm system as set forth in claim 2 wherein the indicating means includes a smoke detector.

4. An alarm system as set forth in claim 2 wherein the removal indication switch senses the removal of a fire extinguisher.

5. An alarm system as set forth in claim 2 wherein the indicating means includes a burglar alarm.

6. An alarm system as set forth in claim 2 wherein each remote unit includes a playback mechanism which is adapted to generate a vocal message upon the receipt of the activation signal, wherein the vocal message is adapted to be transmitted by way of the transmitter.

7. An alarm system as set forth in claim 6 wherein indicating means includes both a fire indicating means and a burglar alarm, wherein the vocal message relates to the indicating means from which the activation signal is received.

8. An alarm system as set forth in claim 6 wherein the vocal message includes a location of the remote unit.

9. An alarm system as set forth in claim 6 wherein the vocal message is transmitted via a loudspeaker mounted on the remote unit.

10. An alarm system as set forth in claim 6 wherein the vocal message is transmitted to a public address system for emitting the same over a plurality of loud speakers.

11. An alarm system as set forth in claim 2 wherein each remote housing includes a microphone for receiving audible vocal distress signals and transmitting the same via free space by way of the transmitter.

12. An alarm system as set forth in claim 11 wherein the audible vocal distress signals are received via a receiver of an emergency personal.

13. An alarm system as set forth in claim 12 wherein each remote housing includes a receiver for receiving audible vocal instruction signals from the emergency personnel via a transmitter of the emergency personnel.

14. An alarm system as set forth in claim 12 further comprising a protective helmet adapted to be worn by at least one of the emergency personnel, the protective helmet having a transceiver mounted therein with a speaker for receiving audible vocal distress signals upon the receipt thereof via free space and a microphone for transmitting audible instruction signals to at least one of the remote units.
