Series 65A Conventional Fire Detection

The Series 65A range of conventional detectors incorporates well-proven sensing technologies, together with advanced materials and electronics technology. A wide operating voltage of 9 to 33V DC means that Series 65A detectors can be integrated into security systems when used with a relay base.

Series 65A Ionization Smoke Detector

The Series 65A Ionization 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.
