煙霧探頭BHH-500

Smoke Detector BHH-500

Interactive smoke detector head with SelfVerify, environmentally protected

BH-500 is a point smoke detector for detection of combustion gases mainly consisting of visible particles. The detector has a built-in thermistor and is designed for use with Autronica’s interactive fire alarm system, AutroSafe, which can provide temperature information from the detector point. The SelvVerify function ensures the highest grade of reliability because all units comprising this function are automatically tested with a calibrated test once every 24 hours. Additional coating of PCB combined with the adaptivity of BH-500, makes this detector suitable for industrial, maritime, offshore and other "rough area" applications.

Applications:

BH-500 is a point smoke detector for detection ofcombustion gases mainly consisting of visible particles.The detector has a built-in thermistor and is designed foruse with Autronica’s interactive fire detection systems,which can provide temperature information from thedetector point. The SelfVerify function ensures the highestgrade of reliability because all units comprising thisfunction are tested with a calibrated test once every 24hours.The DYFI+ intelligence combined with the SelfVerifyfunctions and the allround smoke sensitivity of BH-500makes this detector the obvious choice for demandingapplications such as industrial, maritime and offshoreinstallations. The additional PCB coating makes thisdetector ideal in corrosive and humid environments.Optionally there is a BH-500/N version for use inhazardous area zone 2. It must be connected to the BSD-310/N loop driver, but does not require an isolator/barrierunit.
