Description

The C-TEC C4408D is a high-quality conventional diode base that serves as the critical interface for the ActiV detector range in UK fire systems. By incorporating a Schottky diode between the positive input and output terminals, it enables “head-out” fault monitoring as required by BS 5839-1, ensuring manual call points remain active even if a detector head is removed. With its spacious design, 7-terminal layout for easy wiring, and integrated tamper-locking mechanism, the C4408D provides a secure and efficient mounting platform for any professional fire installation.

Features

  • BS 5839-1 Compliant: Includes a blocking diode that allows the control panel to monitor for detector removal faults.
  • 360° Viewing Angle: Engineered to ensure the dual LED strips on ActiV detectors are perfectly visible regardless of the base’s orientation on the ceiling.
  • Universal ActiV Compatibility: One base fits all: Optical (C4416), Multi-Sensor (C4414), and all Heat Detector variants (C4403).
  • Integrated Security: Includes a “click and twist” locking mechanism, a head removal tool, and a plastic ID tag for zone/device labeling as standard.
  • Installer-Friendly: Features large, tin-plated steel terminals and a spacious design that accommodates up to 2.5mm2 fire-rated cable easily.
  • Remote Indicator Support: Equipped with dedicated terminals for the optional connection of a BF318 Remote LED indicator.
