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

Product description

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

The product serves for the detection of fire danger in the interior spaces of residential and commercial buildings. The detector is not intended for installation in an industrial environment. The detector is fed via the bus of the control panel.

When the detector is used with batteries (3x 1.5 V AA), with which it can be powered, it will continue to function as an independent detector, when the 12 V supply is disconnected (EN 14604).

The detector indicates a fire hazard with the built-in LED indicator and acoustic signaling. (fire siren)

The product JA-111ST consists of two independent detectors - an optical smoke detector and a heat detector. The optical smoke detector works according to 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 burning liquids such as alcohol. That is why the fire detector also includes a built-in heat detector, which reacts more slowly but is better able to detect a fire that generates only a small amount of smoke.
