More Information

'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. Now available to purchase, its key features include:

• 255 devices per loop.
• Autonomous decision-making for faster response times.
• Multiple type codes.
• 40V loop drive voltage.
• Two ‘soft’ addressing options – automatic via the panel or manual via a powerful handheld programmer.
• Powerful multi-level addressing facilitates easy device addition and swapped device identification.
• Multiple functionality at a single address (integrated devices) - due 2019.
• Volumes, tones & detector modes can be changed at compatible panels.
• High-speed data transmission and robust data transfer.
• Intrinsically EN54-13 compliant.
• Provides geographical location of short and open circuit faults (a short circuit isolator is included as standard in every CAST field device).
• Replace device function.
• Programmable multi-function status LED.
• Future seamless integration with other CAST life safety systems reducing energy, servicing, installation and repair costs.
• Designed and manufactured in the UK.

Technical Specifications

Approvals/certificationsCertified to EN54-7 & 17 by the LPCB.
CompatibilityCompatible with C-TEC's XFP/ZFP CAST Protocol Addressable Fire Panels.
TypeOptical (utilises an infrared light source and photodiode).
Application/operationWhen 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.
Application temperaturen/a
Static response temperaturen/a
Supply wiring2-wire, polarity sensitive.
Supply/operating voltage27 to 40V DC.
Quiescent current370µA @ 35V DC.
Alarm current5mA (LEDs illuminated).
Indicators2 LED indicator strips emitting red light when in alarm offering 360º visibility. Optional remote LED.
ConnectionsVia CA408 base: 1 +Ve IN (analogue swich); 2 +Ve OUT (analogue switch); 3 Remote LED +Ve; 4 0V; 5 0V; 6 Screen; 7 Screen.
