JA-151ST Wireless fire and heat detector with siren

Jablotron JA-151ST Wireless fire and heat detector with siren

The JA-151ST consists of two independent detectors - an optical smoke detector and a heat detector. The optical smoke detector works according to the scattered light principle. It is very sensitive to large dust particles present in dense smoke. It is less sensitive to smaller particles generated by the combustion of liquids such as alcohol. Therefore, the fire detector also includes a built-in heat detector, which reacts more slowly, but is better able to detect a fire, which generates only a small amount of smoke.
