Smoke Detectors

    Optical smoke detector IQ8Quad

    Optical smoke detector which works using the light scatter principle to guarantee safe and early detection of fire.


    Optical smoke detector which works using the light scatter principle to guarantee safe and early detection of fire. Responds well to slow-burning, smouldering fires. Intelligent fire detector with decentralized intelligence, automatic function self-test, CPU failure mode, alarm and operating data memory, alarm indicator, soft-addressing and operating indication.
