JA-111ST-A BUS combined smoke and heat detector with fire and intruder siren

Jablotron JA-111ST-A BUS combined smoke and heat detector with fire and intruder siren function

The product is used for the detection of fire hazards 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 used with batteries (3x 1.5 V AA), which can be supplied with power, the detector will continue to function as a stand-alone detector, if the 12 V supply is disconnected (EN 14604).

The smoke detector has a built-in siren that signals fire and burglar alarms. This message is adopted by all detectors in the system!

The detector indicates a fire hazard using the built-in LED indicator and acoustic signalling.

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 present in dense smoke. The product is less sensitive to smaller particles generated by combustion of liquids such as alcohol. Therefore, the fire detector also includes a built-in heat detector, which responds more slowly, but is better able to detect a fire that generates only a small amount of smoke.
