The product is used to detect the risk of fire in the interior of residential and commercial buildings. The detector is not intended for installation in an industrial environment. The detector is powered from the control panel bus.
When the detector is used with batteries (3x 1.5 V AA), with which it can be powered, it will continue to function as a stand-alone detector, if the 12 V power supply is disconnected (EN 14604).
The smoke detector has a built-in siren that signals fire and burglar alarms. This message is accepted by all detectors in the system!
The detector indicates a fire hazard using the built-in LED indicator and acoustic signaling.
The JA-111ST-A product consists of two independent detectors - an optical smoke detector and a heat detector. The optical smoke detector works on the principle of scattered light. It is very sensitive to coarser dust particles that are present in dense smoke. The product 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.
