combined optical smoke and heat alarms, kill hidden fire hazard
The combined optical smoke and heat alarms is also called compound smoke temperature fire detector, smoke temperature integrated detector and so on.
The combined optical smoke and heat alarms, as the name suggests, is to combine the functions of the smoke detector and the temperature detector on the same detector. The combined optical smoke and heat alarms can be used as an independent smoke detector or temperature detector. At the same time, the two detector methods can be effectively combined together to more effectively detect fire alarm. The working principle is broadly speaking, it is a combination of two principles of photoelectric smoke and temperature detector.
In other words,the combined optical smoke and heat alarms unites the advantages of smoke and heat detection in one detector. An intelligent evaluation logic guarantees excellent response behaviour and the lowest possible false-alarm rate. The integrated sounder for audible alarm transmission has a sound pressure of up to 85 dB(A). Like our SR-820DHS（please click the model number to get more info）, it fully meets your needs.
buy it, buy it! buy it! Good things must be said three times, combined optical smoke and heat alarms, kill hidden fire hazard. Sincerely recommend to you！
