Abstract

An alarm system for monitoring alarm conditions and for generating alert signals responsive thereto. The alarm system includes alarm signal processing circuitry for generating signals responsive to alarm conditions, control circuitry coupled to both transmitter and receiver control circuitry which are in turn coupled to a plurality of transceivers located about a selected site. Message control coupled to a recorded audio message unit transmits selected messages, via the transceivers, to portable remote units. Remote personnel respond to signals or messages from the alarm system by means of a portable radio with a built in keyboard In the event that an appropriate response is not received by the control system, dialer control circuitry places a phone call to a predetermined assistance seeking number and a prerecorded message from the message unit states the alarm condition and location.

Claims

1. An alarm system comprising:

means for sensing a selected alarm condition;

control means, coupled to said sensing means, for processing said sensed alarm condition and for generating an alert signal responsive thereto;

means, coupled to said control means, for transmitting said alert signal throughout a selected region;

a portable receiver-transmitter unit for receiving said alert signal and for generating an audio indicia thereof including manually operable means for generating an acknowledge signal responsive to said alert signal;

means, coupled to said control means, for receiving said acknowledge signal;

means, coupled to said control means, for generating and transmitting to said portable unit a verbal directive identifying the sensed alarm and location thereof;

means coupled to said control means, for sensing a second acknowledge signal; and

wherein said unit includes means for generating said second acknowledge signal in response to receiving said verbal directive.

2. An alarm system in accordance with claim 1 wherein said means for transmitting includes a plurality of transmitters and means, coupled to said plurality of transmitters, for selecting one member of said plurality.

3. An alarm system in accordance with claim 2 including a plurality of receivers coupled to said means for selecting one member of said plurality.

4. An alarm system in acordance with claim 2 wherein said control means includes means for generating a plurality of alert signals spaced apart a selected amount in time and spatially distributed in a selected region by said plurality of transmitters.

5. An alarm system in accordance with claim 4 wherein said means for receiving said acknowledge signal includes means for sensing a predetermined elapsed time interval and for activating said means for generating a plurality of alert signals in response to a failure to sense said acknowledge signal within said predetermined time interval.

6. An alarm system in accordance with claim 5 including means for telephonically transmitting a selected message to a predetermined destination in response to a failure to receive said acknowledge signal within a predetermined time interval.

7. An alarm system in accordance with claim 4 including means for generating a system test condition signal, means for transmitting said system test condition signal to said unit and means for detecting a selected acknowledge signal from said unit in response thereto.

8. An alarm system in accordance with claim 7 wherein said means for generating a verbal directive includes means for storing a plurality of verbal directives or messages including means for selecting a predetermined message to be transmitted.

9. An alarm system in accordance with claim 4 including means for sensing a selected emergency signal initiated by said unit and for transmitting via a selected channel an assitance requesting message in response thereto.

10. An alarm system in accordance with claim 9 including:

means for detecting an incoming phone call;

wherein said means for generating a plurality of alert signals includes means for generating a selected alert signal in response to said detected phone call;

means for transmitting said detected phone call to said unit; and

means affixed to said unit, enabling an operator to verbally respond to said detected phone call.

11. An alarm system in accordance with claim 10 including further:

means, affixed to said unit for initiating a phone call; and

wherein said control means includes means for dialing a selected telephone number.

12. A method of sensing an alarm condition comprising:

sensing a selected alarm condition;

generating an alert signal responsive thereto;

transmitting said alert signal throughout a selected region;

receiving said alert signal and generating an audio indicia thereof;

generating an acknowledge signal responsive to said alert signal;

receiving said acknowledge signal;

generating a verbal directive identifying the sensed alarm and location thereof in response to said acknowledge signal; and

sensing a second acknowledge signal in response to said verbal directive.

13. A method in accordance with claim 12 including generating a plurality of alert signals spaced apart a selected amount in time and spatially distributed in a selected region.

14. A method in accordance with claim 13 including sensing a predetermined elapsed time interval and for generating a plurality of alert signals in response to a failure to sense said acknowledge signal within said predetermined time interval.

15. A method in accordance with claim 14 including transmitting a selected message to a predetermined destination in response to a failure to receive said acknowledge signal within said predetemined time interval.

16. A method in accordance with claim 13 including generating a system test condition signal, transmitting said system test condition signal throughout the selected region and detecting a selected acknowlege signal in response thereto.

17. A method in accordance with claim 16 including storing a plurality of verbal directives or messages and including selecting a predetermined message to be transmitted.

18. A method in accordance with claim 13 including sensing a selected emergency signal and transmitting via a selected channel an assistance requesting message in responce thereto.

19. An alarm system usable in a selected region having a plurality of fixed sensor units distributed throughout the region, the system being usable for detecting an alarm signal generated by one or more of the fixed sensor units, for initially signalling an operator located somewhere within the region and carrying a portable unit and for then signalling remote personnel in the event that the operator carrying the portable unit fails to respond, the system comprising:

means, electrically connected to the sensor units, for detecting an alarm signal;

control means, coupled to said detecting means, for processing said detected alarm signal and for generating an alert signal responsive thereto;

means including a plurality of transceivers, coupled to said control means, for transmitting said alert signal throughout the selected region;

a portable receiver-transmitter unit for receiving said alert signal and for generating an audio indicia thereof including manually operable means for generating, essentially immediately, an acknowledge signal responsive to said alert signal;

means, coupled to said control means, for receiving and for detecting the presence or absence of said acknowledge signal within a predetermined period of time;

means, coupled to said control means, for generating and transmitting to said portable unit a verbal message identifying the detected alarm in response to the detected presence of said acknowledge signal; and

means, coupled to said control means, for generating and transmitting to remote personnel a verbal message in response to the detected absence of said acknowledge signal.
