The Series 65 Optical Smoke Detector uses light sensing technology to detect a fire. The external detector moulding has an indicator LED which is white in quiescent state but produces a red light in 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.
