Siemens OOH740 multi sensor smoke detector

• Make: Siemens
• Model code: OOH740
• Type: Smoke

Siemens OOH740 is a multi sensor smoke detector used 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. It 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.
