Jablotron JA-111ST-A BUS combined smoke and heat detector with fire and burglar siren function
The product serves to detect fire hazards in the indoor areas of residential and commercial buildings. The detector is not intended for installation in an industrial environment. The detector is powered via 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 when the 12 V power supply is disconnected (EN 14604).
The smoke detector has a built-in siren that signals fire and burglary alarms. This notification is taken over by all detectors in the system!
The detector indicates fire danger 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 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 is slower to respond, but better able to detect a fire , which generates only a small amount of smoke.
