Optical smoke detector OH720

liquidcombustionmulti-sensor

For the detection of flaming fires caused by the combustion of liquid and solid matters, as well as smoldering fires. For reliable fire detection in environments with deceptive phenomena. Works according to the scattered-light principle with an optical forward scattering sensor. An additional heat sensor increases the fire detector’s immunity to deceptive phenomena. Selectable detection behavior by different parameter sets. Immunity against transient false alarm causes. The base must be ordered separately.
