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. 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.
• Flashing and non-flashing polling LED option.
• Future seamless integration with other CAST life safety systems reducing energy, servicing, installation and repair costs.
• Designed and manufactured in the UK.
