Autronica BHH-520/EXE Multisensor with SelfVerify

The Autronica BHH-520/EXE is a Multisensor for use in hazardous area zones 0, 1, 2. It must be connected to approved barrier BZ-500. 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 BHH-520/EXE ensures an early response to any type of fire development.


The Autronica BHH-520/EXE is also known as:
