The Autronica 116-BHH-520/EX is a multisensor detector, designed for use in hazardous area zones 0, 1 or 2. The BHH-520/EX must be connected to the approved Autronica BZ-500 barrier. 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 principle of the Autronica BHH-520/EX, combined with the advanced signal processing in the detector, ensures an early response to any type of fire development.
The Autronica BHH-520/EX is designed for use with the Autronica AutroSafe and Autroprime interactive fire alarm system.
An additional coating of PCB combined with the adaptivity and the allround smoke sensitivity of BHh-520/EX makes
this detector suitable for industrial, maritime and offshore applications where there is a potential flaming
or/and smouldering fire hazard.
Multisensor detectors ensure fast response to various fire developments
