The simple click and twist design with integrated locking mechanism ensure heads are securely fitted to the base, for reliable connection to the system. Only suitable in some non-UK territories, the Non-Diode means your control panel will not warn you when a detector head is removed.

As a result of C-TEC’s UK-made detector range having a 360° viewing angle thanks to their viewing strips, this means the diode base can be mounted to the ceiling in any orientation. Designed with lots of working space for easy fitting, has terminals accepting 2.5mm fire rated cable, and is IP42 rated. Plus, it features remote LED terminals allowing for the optional installation of a remote indicator.

Compatible with our entire range C-TEC detector, with alternative mounting bases available.
