Apollo 55000-220APO Series 65 Integrating Ionisation Smoke Detector

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
