Abstract

An alarm system apparatus includes a plurality of sets of smoke or heat detectors located throughout a building. A plurality of automatic telephone dialers are also located in the building and each dialer has at least one set of smoke or heat detectors operatively connected thereto. A plurality of localized alarms are connected to the automatic dialer for actuation by the detectors and each automatic dialer is connected to a phone line into a microcomputer having stored thereon the position of each smoke and heat detector. The microcomputer, in turn, has a modem coupling it through the phone lines to a remote terminal. The microcomputer includes a connector for coupling a mobile terminal to the computer from the exterior of the building. In addition, the auto dialer is equipped with a relay for switching in an auxiliary battery supply in the event of power loss.

Claims

1. An alarm system comprising in combination:

a plurality of automatic dialers positioned in a building and each being connected to a telephone line;

a plurality of detectors located in a building, each detector being connected to one of said plurality of automatic dialers for actuating said automatic dialer responsive to said detector being actuated and for generating detector information indicative of the location of said detector;

computer means having a central processing unit microprocessor and storage means therein operatively connected to each of said plurality of automatic dialers over telephone lines for receiving the detector information upon actuation of a detector and for storing and transmitting said detector information, said computer means storage means having additional stored information thereon including data indicating the floor plan of a portion of said building and the location of each detector on said building floor plan, said computer means having a coupling to the outside of a building for coupling to a portable terminal for displaying the detector information and the additional information indicating the location of each detector on said building floor plan without having to enter the building; and

a remote terminal for receiving stored computer information over a phone line from said computer storage means and adapted to receive and store detector information, indicating the location of each detector on said building plan whereby a central alarm system can alert a central station and provide stored information on detector location.

2. An alarm system in accordance with claim 1, in which said computer means includes a modem for transmitting data over telephone lines to said remote terminal for receiving computer information.

3. An alarm system in accordance with claim 2, in which said plurality of detectors includes a plurality of combination heat and smoke detectors.

4. An alarm system in accordance with claim 3, including at least one burglar detector connected to one of said plurality of automatic dialers for actuating said automatic dialer responsive to said burglar detector being actuated.

5. An alarm system in accordance with claim 1, in which said computer means storage means includes a hard disk driver for storing and accessing information thereon.

6. An alarm system in accordance with claim 1, in which each story of a building has at least one automatic dialer thereon and a plurality of detectors connected thereto.

7. An alarm system in accordance with claim 6, in which each detector includes an audible alarm operatively coupled thereto for warning occupants upon the actuation of said alarm.

8. An alarm system in accordance with claim 6, in which each of said plurality of detectors includes a strobe operatively coupled thereto for warning occupants therein of the actuation of said detector.

9. An alarm system in accordance with claim 1, in which each of said plurality of automatic dialers includes at least one rechargeable battery coupled thereto.

10. An alarm system in accordance with claim 9, in which each of said rechargeable batteries is coupled through a relay to a power line for actuation of said relay to cut in said rechargeable batteries upon the loss of power in said power line.

11. An alarm system in accordance with claim 10, in which each said automatic dialer includes a power supply connected to a power line.

12. An alarm system in accordance with claim 11, in which each said automatic dialer has a real time clock operatively coupled thereto.
