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) - coming soon.
• 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.
• Future seamless integration with other CAST life safety systems reducing energy, servicing, installation and repair costs.
• Designed and manufactured in the UK.

VAD coverage (with multiplication factors applied)

VAD coverage depends on factors such as ambient light and viewing angle (direct or indirect). The table below summarises how the coverage of the CA455A/W increases or decreases based on these factors. To use the table, calculate the lux level of the area requiring coverage, determine whether the viewing angle will be direct or indirect then read off the coverage in the relevant column.
