Ionisation detectors use a low activity radioactive foil to detect fires by irradiating the air in the smoke chamber and causing a current flow. If smoke enters the chamber, the current flow is reduced leading to an alarm. Circuitry in the Integrating Ionisation Smoke Detector projects against transient levels of smoke above the normal threshold for up to 20 seconds.

Key Features:

Responds well to fast burning, flaming fires
Designed to operate in environments where transient levels of smoke may be expected
Wide operating voltage
Flashing LED and magnet operated test switch option
