Jablotron JA-82ST Pack, 4 wireless Fire detectors
This device is designed to detect the presence of fire inside residential or commercial buildings. It should not be installed in industrial premises. Alarm information is transferred via the wireless connection to the OASiS control panel.
The JA-82ST detector combines an optical smoke sensor with a heat sensor. Both sensors have their outgoing signals processed digitally, resulting in higher false alarm immunity. The optical sensor works using a light diffusion principle and is very sensitive to the presence of large-sized particles which are characteristic of dense smokes. By contrast, the sensor is less sensitive to small-sized particles which are typical of cleanly burning fires. In particular, the smoke sensor is not capable of detecting the by-products of cleanly-burning fluids such as alcohols, for instance. This deficiency is compensated for by the built-in heat sensor. This sensor provides a slower reaction when compared to the smoke sensor, but is much better at reacting to fires with rapidly rising heat producing only a little smoke. Smoke / heat sensor participation is configurable by jumper-settings.
