BHH-520 Optical/Heat Multisensor Detector with SelfVerify

Optical/Heat Multisensor Detector with SelfVerify – Autronica BHH-520

BH-520 is an optical/heat multisensor detector. A rise in temperature will change the detection platform by  increasing the smoke sensitivity in order 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.

The BH-520 is designed for use with Autronica’s interactive fire detection systems. The DYFI+ intelligence combined with the SelfVerify functions and the allround smoke sensitivity of BH-320 makes this detector the obvious choice for demanding applications such as industrial, maritime and offshore installations where there is a potential flaming or/and smouldering fire hazard. The additional PCB coating makes this detector ideal in corrosive and humid environments.

Optionally there is a BH-520/N version for use in hazardous area zone 2. It must be connected to the BS-310/N loop driver. Does not require an isolator or a barrier unit.
