Multiple alert smoke detector
First Claim
1. A multiple alert smoke detection system comprising:
- (a) a minimum of two multiple alert smoke detectors, each detector comprising sensor means for sensing the presence of smoke, each detector comprising an audible alarm;
(b) each detector comprising means for actuation of said audible alarm for the duration of the sensor means sensing of the smoke;
(c) each detector comprising means for wireless direct communication with other smoke detectors of said system, each detector comprising a transmitter for transmitting user selectable, coded frequency modulated radio signal transmission, each smoke detectors comprising user selectable, coded frequency modulated radio receiver each detector emitting an audible pattern defined by the radio signal received by the detector.

Abstract
The battery powered smoke detector of the present invention is designed to provide an early warning of the presence of an environmental condition of fire or smoke to persons in remote areas of a building with respect to the location of the environmental condition. The smoke detector sensing the environmental condition emits an audible alarm of continuous tone, while emitting a frequency modulated radio signal directly to other like smoke detectors to activate their alarms in a manner indicative of the location of the smoke detector sensing the environmental alarm condition. Rechargeable light modules separate from the smoke detector are included that receive the frequency modulated radio signal from the smoke detector sensing the environmental alarm condition and illuminate paths of egress for the duration of the alarm condition or in case of 120VAC power failure. All components of the system are easy to install due to the modular design and conventional power sources. An intermittent activation of the frequency modulated receiving circuitry in the smoke detector unit conserves battery energy.
