Exi Optical smoke detectors
An optical smoke detector detects the occurrence of an early-stage fire by measuring the density of the smoke. In the event of an alarming smoke density, an increased current flows through the detector and thus reports the fire to the fire alarm panel.
The optical detector is intended for long-term use because of its robustness and the ability to clean the light chamber in the detector.
