Standard slim common mounting base is compatible with the complete range of detectors allowing detectors to be easily interchanged. The base incorporates a continuity diode to allow monitoring of detector removal whilst maintaining circuit integrity to comply with BS5839 pt1 1988.A security screw in the detector head locks into the base to prevent unauthorised removal of detectors.

Detector Relay Base Combined within the standard detector base housing, the relay base is available in either normally open or normally closed configuration. The relay contacts change state when the detector plugged into that base detects a fire condition.Contacts Rated at 1A @ 30v AC/DC
