Multi-function combustion detecting device
First Claim
1. An improved warning device, comprising means for detecting the occurrence of predetermined phenomena;
- means for interconnecting said device with at least one other warning device which generates an interconnect signal when the other warning device detects said predetermined phenomena, and indicator means for generating a first sensibly discernible signal in response to said detecting means detecting said phenomena, a second sensibly discernible signal in response to the occurrence of the interconnect signal, a third sensibly discernible signal whenever neither of said first and second signals is being generated and means for monitoring the sensitivity of said detector means to said phenomena, said indicator means generating a fourth sensibly discernable signal in response to said sensitivity decreasing to at least a selected level, said indicator means generating said third sensibly discernable signal whenever none of said first, second and fourth signals is being generated.

Abstract
A battery powered products of combustion detector and warning device, which is interconnectable in a detecting system with other similar devices, is characterized by means for providing separate, distinct and sensibly perceptible signals representative of (a) a standby or quiescent condition of the device, (b) the energy level of the battery decreasing to at least a predetermined level, (c) the sensitivity of the device to the phenomena decreasing to at least a selected level, (d) detection by the device of the occurrence of the phenomena, or (e) detection of the phenomena by another warning device interconnected therewith. In consequence, a user of the warning device is readily and continuously apprised of the operating condition and state of the device.
