The Siemens Digital Industry Multisensor Smoke Detector OOH740 is designed to warn against flame fires from solid and liquid materials as well as smoldering fires. It provides reliable fire detection in environments with distracting sizes. The device operates on the light scattering principle with two sensors that utilize forward and backward light scattering. The optoelectronic sampling chamber blocks disruptive stray light while effectively detecting both dark and light smoke particles. Two additional heat sensors enhance the detector's resistance to false alarms.

In collection mode, you can choose from three parameter sets: Standard Plus (PS1), Suppression (PS5), and High Sensitivity Fast (PS9). Please note that the base must be ordered separately.

Scope of delivery: Detector and dust protection cap.
