Distinctive features
- Fast operation: giving the “Fire” signal within 0,2 - 0,5 seconds from the moment of ignition;
- Interference immunity at the cut of the window with background light without giving the “Fire” signal: for scattered sunlight - to 5000 lux; for fluorescent lamps - to 2500 lux; for incandescent lamps - to 250 lux;
- The ability to detect smoldering fires by applying of forced modulation of the light flux;
- The possibility to conduct periodic remote check of sensors due to the built-in simulator of infrared radiation.
