Siemens OOH740 Cerberus PRO ASA Dual Optical Heat Multi-Sensor Detector (S54320-F7-A3)
Product Details for Siemens OOH740 Cerberus PRO ASA Dual Optical Heat Multi-Sensor Detector (S54320-F7-A3)
The Siemens OOH740 ASA detector is 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 two sensors, optical forward and backward scattering. Opto-electronic sampling chamber blocks disturbing extraneous light but optimally detects both dark and light smoke particles. Two additional heat sensors increase the fire detector’s immunity to deceptive phenomena.
In the collective mode you have the possibility to choose between three parameter sets: Standard Plus (PS1), Suppression (PS5) and High Sensitive Fast (PS9).
The base must be ordered separately.
