The Cerberus OOH740 is designed for the detection of flaming fires caused by the combustion of liquid and solid matters, as well as smoldering fires. The OOH740 is built for reliable fire detection in environments with deceptive phenomena.
The Cerberus OOH740 works according to the scattered-light principle with two sensors, optical forward and backward scattering. The opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects both dark and light smoke particles.
