Interactive MultiSensor detector head with SelfVerify, environmentally protected. Ex ic version of BHH-520.

A temperature rise will change the detection platform by increasing the smoke sensitivity to improve the detection of combustion gases from flaming fires producing barely a minimum of visible smoke particles. The MultiSensor principle combined with advanced signal processing in the detector ensures an early response to any type of fire development.

BH-520/N is designed for use with Autronica’s interactive fire detection systems. The SelfVerify function ensures the highest grade of reliability. All units comprising this function are automatically tested with a calibrated test once every 24 hours.

The detector is for use in hazardous area zone 2. It must be connected to a loop driver approved for zone 2. An additional coating of PCB combined with the adaptivity and the round smoke sensitivity of BH-520/N makes this detector suitable for industrial, maritime, and offshore applications where there is a potential flaming or/smoldering fire hazard.
