The CAST Hi-Output Wall VAD 103 dB(A) Sounder (Shallow Base) is a premium addressable combined sounder and Visual Alarm Device (VAD) designed for use with C-TEC CAST addressable fire alarm systems. Engineered to provide powerful audible and visual fire alarm notifications, this advanced device delivers an impressive 103 dB(A) sound output at 1 metre and a certified high-performance visual alarm, ensuring rapid occupant alerting during fire emergencies. It is ideal for commercial, industrial, educational, healthcare, hospitality, and public buildings where dependable life safety systems are essential.

Built on C-TEC’s CAST (C-TEC Addressable System Technology) distributed intelligence protocol, the device offers fast communication, intelligent monitoring, and reliable alarm activation. Each sounder/VAD incorporates onboard processing and an integrated short-circuit isolator, improving system resilience and helping maintain operation even if a loop fault occurs.

The integrated Visual Alarm Device (VAD) is certified to EN54-23 and provides a W-2.75-9 rated light distribution, while also being certified as a W-4-4 VAD. The high-intensity white LED beacon ensures effective visual notification for occupants, including those with hearing impairments or in noisy environments where audible alarms alone may not be sufficient.

Delivering an impressive 103 dB(A) sound output, the sounder provides clear and effective audible warning across a wide range of building types. The device offers 31 selectable alarm tones and 4 selectable volume levels, allowing installers to customise alarm characteristics to suit different applications and local fire safety requirements. Group addressing functionality enables multiple devices to operate simultaneously, simplifying programming and improving evacuation management.

Designed specifically for indoor wall-mounted installations, the shallow base provides a compact, professional appearance while reducing installation depth. Its low-profile design makes it ideal for offices, schools, hospitals, hotels, shopping centres, apartment buildings, and other modern facilities where aesthetics and performance are equally important.

The device incorporates an onboard short-circuit loop isolator, helping protect the integrity of the addressable loop by automatically isolating faults. This reduces the impact of wiring faults and ensures that unaffected devices continue operating, increasing overall system reliability and reducing maintenance downtime.

Operating on 27–40 V DC, the CAST Hi-Output Wall VAD features exceptionally low power consumption, with a typical quiescent current of 460 µA and a typical alarm current of approximately 13.5 mA when the VAD is active and the sounder is operating at maximum volume. This energy-efficient design allows more devices to be installed on each addressable loop without compromising system performance.

Certified by independent approval bodies, the unit is LPCB certified to EN54-3, EN54-17, and EN54-23, Kiwa Telefication and DBI certified to EN54-13, and also certified by SBSC to the relevant EN54 standards. These approvals demonstrate compliance with internationally recognised fire detection and alarm system requirements, providing confidence in long-term reliability and performance.

Constructed from durable, flame-retardant materials, the device features an IP21C ingress protection rating, making it suitable for indoor environments where protection against accidental water ingress and dust is required. Its robust construction ensures dependable long-term operation while maintaining an attractive, professional appearance.

The CAST Hi-Output Wall VAD 103 dB(A) Sounder (Shallow Base) is ideally suited for installation in:

Whether installed as part of a new addressable fire alarm system or used to upgrade an existing CAST installation, the CAST Hi-Output Wall VAD 103 dB(A) Sounder (Shallow Base) delivers exceptional audible and visual alarm performance, intelligent addressable functionality, and industry-leading reliability. Its powerful sound output, certified VAD coverage, integrated short-circuit isolation, flexible programming options, and compliance with multiple EN54 standards make it an excellent choice for professional life safety applications.
