Product Overview

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

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
