Optical smoke detector OOH740

thermalmulti-sensorfor fire safety applications

Product description
Multi-sensor smoke detector OOH740 with ASA Technology for reliable detection of flaming and smoldering fires. Operates on the scattered-light principle with two optical sensors (forward and backward scattering). The opto-electronic sampling chamber suppresses stray light while detecting both dark and light smoke particles. Two additional heat sensors increase immunity to nuisance sources. Collective mode offers three parameter sets: Standard Plus (PS1), Suppression (PS5) and High Sensitive Fast (PS9). The base must be ordered separately.
