The CAST-PRO CO Fire, Smoke and Heat Multisensor with Tone Sounder and C-3-9.4 White VAD (CP411TV) from C-TEC is a highly advanced detection and alarm device designed for use with modern addressable fire systems. It combines multiple life safety functions into a single unit, including carbon monoxide detection, smoke sensing, heat measurement, an integrated audible alarm and a certified visual alarm device. By integrating these features in one compact housing, the unit provides comprehensive protection while reducing installation complexity and overall system costs.
At the heart of the device is its multisensor capability, which allows it to monitor for carbon monoxide, heat and smoke signatures simultaneously. This enables it to respond quickly and effectively to a wide range of fire conditions. It is supported by C-TEC’s advanced MASC™ chamber design and AFFIRM™ algorithms, which ensure high resistance to false alarms and maintain stable performance over time through built-in drift compensation. The multisensor offers twelve detection modes, with Mode 10 as standard, allowing installers to configure the device for smoke, heat, CO or various combinations depending on the environment and risk profile.
The integrated tone sounder provides a 92 dB(A) alarm signal, ensuring clear and effective warning in an emergency. Complementing this is the C-3-9.4 White Visual Alarm Device, which delivers efficient light output with a synchronised flash rate of 0.5 Hz. Together, the audible and visual components provide an effective means of alerting building occupants, including those with hearing impairments, in compliance with the requirements of EN54. Dual ultra-bright red LEDs provide 360-degree visibility of alarm status, further enhancing its signalling performance.
As part of the CAST protocol range, the device is fully compatible with C-TEC’s ZFP and XFP control panels. It features an integrated short-circuit isolator to maintain loop integrity, ensuring that faults are localised without affecting the wider system. The product is certified to multiple EN54 standards, including parts 3, 5, 7, 13, 17, 23, 29 and 31, confirming its suitability for use in professional fire detection and alarm installations.
With an operating voltage of 28–40 V DC and a typical alarm current of 13.2 mA when both the sounder and VAD are active, the device offers excellent efficiency. Measuring 105 mm in diameter and weighing just 133 g without the base, it is compact and unobtrusive while delivering powerful performance. Its operating temperature range of –10 °C to +50 °C and humidity tolerance of up to 95 per cent non-condensing make it suitable for a wide variety of installation environments.
The CP411TV represents a reliable, technically advanced solution for specifiers and installers seeking to provide robust, multi-hazard detection and alarm signalling. By uniting sensing, sound and visual indication in one unit, it delivers the highest standards of protection, efficiency and compliance for today’s fire safety requirements.
