The B324RL has been designed to provide interfacing between a Series 300 detector and 24V fire control panels or power supplies that require an external contact to activate an ancillary piece of equipment. The relay is controlled directly from the detector. Therefore, in an alarm condition both the detector and relay base will latch into alarm, and can only be reset by removing the supply voltage from the detector. A break off tab allows the base to be connected to a range of fire control panels. This tab should be broken when there is little current flow or no current limiting resistor such as when used as a stand-alone system powered by a 24V supply.
