Siemens OOH740, S54320-F7-A3
Multi-sensor smoke detector, ASA, S54320-F7-A3
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.
