AR-025 Smoke detector

AR-025 Smoke detector for zone 2The explosion-safe Artidor AR-025 optical smoke detector reacts to visible smoke particles. If too much smoke enters its measuring chamber, an alarm is triggered. In the measuring chamber, an integrated infrared light source generates a light pulse every 8 seconds. Smoke particles from a fire change the light signal received by the light diode. A relay trips and the alarm center reports a fire alarm. The 12 V optical smoke detector is mounted on the ceiling in the center of the room. The minimum distance to the side wall should be 30cm. We recommend a separate smoke detector for each entrance area, staircase, living-room, and bedroom. By changing a jumper, you can configure the optical smoke detector as NO or as NC detector. It is therefore suitable for every wired alarm system. The smoke detector is supplied externally with 12V operating voltage and is EN54 certified.

The AR-025 Smoke detector is mounted on top a coated aluminum housing. The explosion safety is arranged by the application of protection degrees against ignition “Increased safety” and “molding”.

The Artidor AR-025 Smoke detector is certified in accordance with European Directive 2014/34/EU (ATEX 114) and is CE marked.
