Abstract

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 Analysis

Total Claims: 13
Claim 1
Independent Claim 239 words
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.
Claim 2
Dependent Claim 239 words
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.
