Relay base can be used for fire and security applications
Published: July 2006
A low-profile 12 V relay base for Apollo’s Series 65 conventional smoke and heat detectors can be used in both fire and security systems, depending on whether latching or non-latching mode is selected. There is a single-pole, voltage-free changeover contact for switching ancillary equipment. In the latching mode, the contact remains in the changed state until the detector is manually reset. In non-latching mode, the contact automatically resets both itself and the detector. The relay base is operated by the detector and must be fitted with a Series 65 smoke or heat detector to function. A one-way fit prevents a detector being fitted incorrectly. The Series 65 range of conventional detectors includes ionisation and integrating ionisation smoke detectors, optical smoke detects and heat detectors. Related articles:
