Product Overview
The Discovery Ionisation Smoke Detector uses a low activity radioactive foil to irradiate the air in the smoke chamber causing a current flow. If smoke enters the chamber, the current flow is reduced leading to an alarm. Responds well to fast-burning, flaming fires. Designed to operate in a variety of environments. Remote test feature.
