Good device but poor install design Poor design from the manufacture, requires a plasterboard box cut into the ceiling as the socket with only single insulated wiring is at 90degs to the detector. Why did they not build it like all normal system detectors where the base has screw terminals and the detector just clips onto.

Well designed and easy to replace when necessary. They work well, and the test and alarm buttons are now much improved.
