Ajax EN54 FireProtect Sounder/VAD Jeweller 118601.279.RD1 (Red)

Introduction — what the Ajax EN54 FireProtect Sounder/VAD offers

TheAjax EN54 FireProtect (Sounder/VAD) Jeweller — 118601.279.RD1 (Red)is a professional, EN54‑certified wireless fire alarm notification device that combines an audible sounder and a visual alarm device (VAD) in a single compact enclosure. Designed for integration with Ajax Fire Hub and Fire ReX control equipment over the Jeweller two‑way wireless protocol, this unit delivers synchronised audio and visual signalling, long battery life, and the compliance expected for commercial installations.

Key highlights include EN54‑3, EN54‑23 and EN54‑25 certification, selectable acoustic output up to 100 dB at 1 m, a VAD LED frame flashing to EN54‑23 timing, and a typical battery life of up to five years on four CR123A cells.

Detailed specifications and the benefits they bring

• EN54‑3 / EN54‑23 / EN54‑25 compliant:Meets core European standards for sounders, visual alarm devices and system compatibility, making it suitable for regulated commercial and public installations when used as part of an EN54 line.
• RED (2014/53/EU):Conforms with radio equipment directives ensuring regulatory compliance across supported regions.

• Sound output:Adjustable up to 100 dB at 1 m and 32 selectable tones — allows installers to match local audible requirements and reduce nuisance alarm issues.
• VAD:LED frame flashes at EN54‑23 timing (90 ms ON / 1,910 ms OFF — 0.5 Hz), providing clear visual annunciation for noisy environments or where audible signals may not be sufficient.
• Synchronisation:Audio and VAD signals can be synchronised across multiple devices controlled by the same control equipment for consistent notification across a building.

• Jeweller protocol:Bidirectional communication for reliable device status monitoring and fast detection of signal faults.
• Range:Up to ~1,700 m open‑field (region dependent), enabling flexible placement in large sites or campus environments when line of sight permits.
• Security:AES encryption and adaptive RF output improve resilience to interference and eavesdropping; polling interval is configurable (12–300 s) to balance responsiveness and battery life.

• Battery power:Runs on 4 CR123A lithium cells (pre‑installed), with tool‑free replacement. Typical battery life is up to 5 years under default polling settings, minimising maintenance visits.
• Ingress and build quality:IP54 rated for dust and splashing water protection, made from UL94 V‑0 material for improved fire safety of the enclosure itself.
• Mounting and tamper protection:Suitable for wall or ceiling mounting; compatible with Ajax SmartBracket and offers anti‑tamper detection and optional locking for secure installations.
• Form factor:Compact dimensions (145 145 51 mm) and weight of approximately 561 g.

Use cases and scenarios where the device excels

The Ajax EN54 FireProtect Sounder/VAD is intended for indoor professional and commercial environments that require certified alarm notification without the complexity and cost of running signal cabling between devices. Typical scenarios include:

• Heritage or retrofit buildings:When preserving architecture prevents chasing walls or ceilings for cabling, a wireless EN54‑certified device provides compliant notification with minimal disruption.
• Complex or multi‑storey buildings:Rapid deployment across floors or separate wings is simplified by long wireless range and synchronised signalling.
• Temporary or modular buildings:Construction site offices, temporary healthcare units or event spaces benefit from fast installation and later reuse without rewiring.
• Noisy industrial spaces:The combination of up to 100 dB output and a bright VAD makes the device suitable where audible alarms alone may not be heard reliably.
• Multi‑occupancy premises:Schools, retail centres, offices and shared facilities where consistent, synchronised notification is required across multiple devices.

Comparisons with similar products in the market

When evaluating notification devices there are several key distinctions to consider: certification status, wired vs wireless architecture, synchronisation capability, battery life, and installer convenience. The Ajax EN54 FireProtect stands out in a number of these areas:

• EN54 certification:Some wireless notification devices are designed for consumer or private use and lack EN54 certification. For regulated public and commercial installations, EN54 compliance is a decisive advantage for the Ajax EN54 FireProtect.
• Integrated sounder + VAD:Many systems use separate sounders and strobes; the combined enclosure reduces installation time, simplifies aesthetics and ensures the two modalities are matched and synchronised out of the box.
• Wireless range and resilience:The Jeweller protocol offers a long open‑field range and two‑way status monitoring. Compared with short‑range proprietary radios, this can reduce the number of repeaters or additional infrastructure required.
• Battery life and maintenance:Up to five years on commonly available CR123A cells with tool‑free replacement lowers total cost of ownership versus devices with shorter life or sealed batteries that require more frequent service calls.
• Professional features:Configurable polling intervals, 32 tones, adjustable sound output and tamper locking make this device installer‑friendly and adaptable to site requirements, while some consumer alternatives limit configuration or lack tamper detection.

That said, hardwired EN54 sounder/VAD units still have advantages in some contexts: they do not rely on batteries, they avoid potential RF interference issues, and they integrate directly with traditional wired fire alarm panels. The choice depends on site constraints, lifecycle cost considerations, and local regulations. In many retrofit, temporary or low‑disruption installations, the wireless Ajax solution provides a compelling balance of compliance and convenience.

Conclusion — why choose the Ajax EN54 FireProtect Sounder/VAD

The Ajax EN54 FireProtect (Sounder/VAD) Jeweller 118601.279.RD1 brings together professional EN54 certification, flexible wireless deployment and practical installer features in one compact unit. It is particularly well suited to retrofit projects, temporary structures and sites where running cabling is impractical or cost‑prohibitive. With selectable tones up to 100 dB, a compliant VAD pattern, synchronisation across devices, and long battery life, it balances performance with lower installation and maintenance overheads.

For projects that require EN54 compliance combined with the convenience of wireless installation, the Ajax EN54 FireProtect Sounder/VAD is a strong option. Always consult a competent installer or authorised Ajax partner to verify spacing, coverage and system design to meet local regulations before deployment.
