For reliable fire detection in environments with deceptive phenomena.

Scope of delivery
Detector and dust cap


Application

For the detection of flaming fires caused by the combustion of liquid and solid matters, as well as smouldering fires.
For reliable fire detection in environments with deceptive phenomena.

 


Function
Works according to the scattered light principle with one sensor, optical forward scattering.
Opto-electronic sampling chamber holds off disturbing extraneous light but optimally detects smoke
particles.

An additional heat sensor increases the fire detectors immunity to deceptive phenomena.
Selectable detection behaviour by different parameter sets.

Immunity against transient false alarm causes.
