SKU: CA416 Category: Brand:


The CA416 is a high-quality smoke detector for use with C-Tec’s XFP & ZFP ‘CAST’ protocol addressable fire panels.

CAST is the world’s most-advanced ‘distributed intelligence’ fire alarm system protocol. Conceived, designed and realised by C-TEC as part of a five-year, multi-million pound project, it involved the creation of a powerful proprietary communication protocol (C-TEC Addressable System Technology, CAST) and multiple control panels & field devices.


  • A high-quality smoke detector for use with C-Tec’s XFP & ZFP CAST protocol addressable fire panels.
  • LPCB certified to EN54-7 & 17 and Kiwa Telefication certified to EN54-13.
  • Smart algorithms help reduce false alarms.
  • Onboard short circuit loop isolator.
  • Includes two 8mm x 2mm ultra-bright red LED indicating strips.
  • Drift compensation functionality.
  • 0.16dB/m sensitivity/obscuration level.
  • 5mA typical alarm current (370uA typical quiescent) @ 22-40V DC
  • Programmable multi-function status LED.
  • Compatible with C-TEC’s CA408 CAST base c/w integrated locking mechanism & ID tag.


  • Approvals/Certifications : LPCB certified to EN54-7 & 17 and Kiwa Telefication certified to EN54-13
  • Compatibility : Compatible with C-TEC’s XFP/ZFP CAST protocol addressable fire panels
  • Type : Optical (utilises an infrared light source and photodiode)
  • Application/Operation : When there is no smoke, light passes in front of the photodiode in a straight line. When smoke enters the chamber across the path of the IR beam, light is scattered, some of which falls on the photodiode triggering the alarm.
  • Sensitivity : 0.16dB/m
  • Supply Wiring : 2-wire, polarity sensitive
  • Supply/Operating Voltage : 22 to 40V DC
  • Quiescent Current : 370µA typical @ 22 to 40V DC
  • Alarm Current : 5mA typical (LEDs illuminated) @ 22 to 40V DC
  • Indicators : 2 LED indicator strips emitting red light when in alarm offering 360º visibility. Optional remote LED.
  • Connections : Via CA408 base: 1 +Ve IN (analogue swich); 2 +Ve OUT (analogue switch); 3 Remote LED +Ve; 4 0V; 5 0V; 6 Screen; 7 Screen.
  • Dimensions :
    • Detector Only : 102.2mm diameter x 37mm deep
    • Detector In Base : 102.2mm diameter x 57.5mm deep
  • Construction & Finish : White polycarbonate casing rated to UL94 V-2 with nylon parts
  • IP Rating : IP42
  • Weight :
