The Ajax FireProtect Jeweller EN54 Wireless Addressable Sounder/VAD combines audible and visual fire alarm notification within a single wireless device, offering an efficient and space-saving solution for professional fire alarm installations requiring both sound and visual indication.

Designed for use with compatible Ajax EN54 wireless fire alarm systems, this combined sounder and VAD is ideal for commercial buildings, refurbishment projects and larger installations where minimising cabling and simplifying installation are key considerations. By integrating both notification functions into one unit, the device helps reduce hardware requirements, streamline system design and improve installation efficiency.

The sounder delivers up to 100dB of audible alarm output at 1 metre, with adjustable volume levels and 32 selectable tones to accommodate different site requirements. Integrated visual alarm indication is provided by a high-visibility LED frame, supporting applications where both audible and visual warning signals are needed for effective occupant notification.

The visual alarm operates with a flash pattern of 90ms ON and 1,910ms OFF, running on a 2,000ms cycle at 0.5Hz. Defined coverage areas assist with compliant installation planning, offering an 8m coverage diameter when ceiling mounted at 3m, or wall coverage of 2.4m x 8.2m x 8.2m when installed at a height of 2.4m.

Powered by Ajax Jeweller wireless communication technology, the device supports communication ranges of up to 1,700 metres in open space with compatible control equipment, helping maintain stable connectivity across larger systems. Alarm activation occurs within 3 seconds, while QR code pairing, SmartBracket mounting, app-based setup and tool-free battery replacement all help simplify commissioning and maintenance.

With pre-installed batteries providing up to 5 years of operation, the Ajax FireProtect Jeweller EN54 Sounder/VAD is designed for reliable long-term performance in professional wireless fire alarm applications.
