The B312NL has been designed to provide interfacing between a Series 300 detector and 12V security control panels that do not provide a reset facility, as the relay base is self-resetting. Therefore, the relay base will automatically reset the Series 300 detector when a fire alarm condition no longer exists. While the detector is in alarm the LED will be on, although it will flash when an alarm check is performed.
