The ABUS RM1000 12V 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 centre reports a fire alarm. The 12V 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. * RM1000 * Suitable for connection to alarm and fire detection systems * Detects visible smoke particles * Self-adjusting * Potential-free alarm relay * Tested according to EN54-7 * 46 x 100mm (H x D) * Screw terminal NO or NC, 1A at 30V DC connections * Optical detection * ABS housing material * 0.368 power consumption * 50°C max. operating temperature * 95% max. humidity * Ceiling installation location * 0.13kg net weight * Photodiode sensor type * 10.5-13.8 VDC voltage supply * 35mA power consumption * EN54-7 certified Optical Smoke Detector · Operating instructions (German) https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2025-02-24 https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2025-07-07 https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2025-09-05 https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2025-12-21 https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2026-03-02 https://elecena.pl/product/27903468/abus-rm1000-12v-optical-smoke-detector 2026-04-18
