C-TEC C4408 ActiV Non-Diode Base – For Addressable Fire Alarm Detectors The C-TEC C4408 ActiV Non-Diode Base is a standard C4 detector base designed for use with C-TEC’s ActiV range of addressable fire detectors. It provides a reliable and easy-to-install platform for detector mounting where diode isolation is not required on the loop. This base is ideal for installations where continuity of detection is not critical in the event of device removal — such as end-of-line locations or specific system designs. Key Features: Part number: C4408 Non-diode version – suitable where loop isolation is not essential Designed for use with C-TEC ActiV addressable detectors Low-profile, C4 base design for neat installation Simple, secure wiring terminals Flame-retardant construction Conforms to BS EN 54 standards Suitable for a wide range of commercial and industrial applications Use the C4408 base where uninterrupted loop continuity is not required, and save on system cost without compromising quality or compliance.
