The Autronica 116-BHH-520/N is an EExn multisensor detector for use in Zone 2 only. The BHH-520/N based on an optical point smoke detector combined with a temperature sensor. A rise in the temperature will change the detection platform by increasing the smoke sensitivity in to improve the detection of combustion gases from flaming fires that produce a minimum of visible smoke particles. The multisensor principle, combined with the advanced signal processing in the detector, ensures an realy response to any type of fire development.

The Autronica 116-BHH-520/N is designed to be used with the Autronica Autrosafe and Autroprime interactive fire detection systems. The DYFI+ intelligence combined with the SelfVerify functions and the allround smoke sensitivity of BHH-520/N 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 the Autronica BHH-520/N ideal in corrosive and humid environments.
