The Series 65 12V Relay Base is designed for use in both fire and security systems. For fire systems a jumper on the PCB is fitted to a ‘latching’ position. For security systems the jumper is moved to another position so that the base is ‘non-latching’.
The Series 65 range has a wide operating voltage of 9–33V and consists of optical smoke detectors, four grades of heat detector and a range of bases.
