Discovery Addressable Ionisation Smoke Detector

Discovery Ionisation Smoke Detector

The Discovery Addressable 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.
