Suitable for installing as part of your conventional fire alarm system for connecting optical smoke, heat, and multi-sensor detector heads, giving a reliable and secure fitting.

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, and will alert your system when a detector head is removed from the base.

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