The Intelligent Low Power Relay Base, which is a development of the standard XP95 base and for indoor use only, incorporates a relay to control field equipment. 
 
The Intelligent Low Power Relay Base gives a set of volt-free changeover relay contacts controlled by the remote output of a detector. By using a latching relay coupled to an efficient drive circuit, the unit operates like a conventional relay while having negligible current drain. 
 
The base also retains the facility to drive a remote LED which mimics the detector remote output.
