The Series 65 Ionisation Smoke Detector uses 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.
Series 65 incorporates well-proven sensing technologies, including an Integrated Circuit based on that used in XP95 analogue addressable detectors. The Series 65 range has a wide operating voltage of 9–33V and consists of ionisation, integrating ionisation and optical smoke detectors, four grades of heat detector and a range of bases.
Responds well to fast burning, flaming fires
Designed to operate in a variety of environments
Flashing LED and magnet operated test switch option
