The C-TEC C4403B ActiV High Temperature Heat Detector is a robust Type B device engineered to activate at a fixed temperature of 75°C.
Designed for demanding environments such as boiler rooms, industrial workshops, and commercial kitchens, it delivers reliable detection without the risk of nuisance alarms from smoke or steam.
Proudly manufactured in the UK by C-TEC, this detector is third-party certified to EN54-5 by Intertek and provides exceptional performance at an accessible price point.
With a wide operating voltage of 6–33V DC, it integrates easily into conventional fire alarm systems.
Fitted with two ultra-bright 8mm x 2mm red LED strips, the C4403B offers 360° alarm visibility, ensuring clear indication of status from all directions.
It’s fully compatible with the full range of ActiV bases including the C4408 (standard), C4408D (diode), and C4408R (relay) – available separately.
Fixed 75°C activation – Type B detector for use in high-temperature environments
Dependable performance – Engineered and manufactured in the UK by C-TEC
EN54-5 certified – Independently tested and approved by Intertek
Versatile voltage range – Operates from 6V to 33V DC
360° LED indication – Dual 8mm x 2mm red LEDs for maximum visibility
Flexible base options – Compatible with C4408, C4408D, and C4408R ActiV bases (sold separately)
