Ajax EN54 FireProtect Sounder Jeweller, 100 dB, Wireless, 118602.278.WH1

Introduction to the Ajax EN54 FireProtect Sounder Jeweller — 118602.278.WH1

Ajax EN54 FireProtect Sounder Jeweller (118602.278.WH1)is an EN54‑certified wireless addressable fire alarm sounder designed for professional and multi‑residential installations that require certified audible notification devices. Combining a high‑output 100 dB alarm, 32 selectable tones, and AjaxN54 control system compatibility, this unit targets installers and specifiers who need the flexibility of wireless deployment without compromising on certification and synchronisation capability.

Key features at a glance

• EN54 certification:Designed to work with Ajax EN54 control equipment (EN54‑3 / EN54‑25 referenced), providing compliance for regulated installations.
• Loud, configurable alarm:Up to 100 dB at 1 m with 32 selectable tones and synchronised activation across devices for consistent site signalling.
• Reliable wireless communications:Uses Ajax Jeweller two‑way proprietary protocol with manufacturer‑stated open‑space range up to ~1,700 m (site dependent).
• Battery powered with long life:Ships with 4× CR123A preinstalled, tool‑free replacement and multi‑year battery life under normal polling.
• Quick installation and tamper protection:SmartBracket mounting supports wall or ceiling installation and provides tamper detection.

Detailed specifications and benefits

• EN54 certified (referenced EN54‑3 and EN54‑25). This is critical where local regulations require EN54 compliance for fire alarm systems in commercial and multi‑residential buildings.
• Designed to be part of an EN54 system when paired with compatible Ajax EN54 control panels and system components. Installation and commissioning should be performed by qualified installers to meet EN54 system requirements.

• Sound output: Up to 100 dB at 1 m. This level is sufficient for most indoor public and commercial spaces when placed according to EN54 spacing and installation guidance.
• Tones: 32 selectable sound patterns allow tailoring alerts for different zones or applications. Synchronisation across multiple units ensures coherent evacuation signalling and reduces confusion in complex sites.

• Protocol: Jeweller proprietary two‑way wireless communications provide fast, reliable signaling and device supervision.
• Range: Manufacturer states up to ~1,700 m in open space. Real‑world range will depend on building materials, site layout, and sources of radio interference; installers should verify link quality during commissioning.
• Two‑way link benefits: Enables status reporting, supervision, and reduced false alarm risk thanks to confirmed message delivery and device health reporting.

• Power: 4 × CR123A batteries preinstalled; tool‑free battery replacement simplifies maintenance and reduces downtime.
• Battery life: Typical multi‑year life (manufacturer suggests up to ~5 years in normal polling modes). Actual life will depend on polling interval, alarm activations, and environmental conditions.
• Tamper protection: SmartBracket mounting provides straightforward mounting and tamper detection to support system integrity.

• Dimensions: Approx. 145 × 145 × 51 mm; weight approx. 527 g (variant dependent).
• Environmental limits: Operating temperature roughly −10 °C to +50 °C and humidity up to ~80% (check datasheet for precise limits).
• Ingress protection: Reseller lists IP54 for some sounder variants; confirm the exact variant and IP rating if the installation requires higher dust/water protection or is in semi‑exposed areas.

Benefits for installers, system designers and end users

• Compliance without extensive wiring:EN54 certification plus wireless connectivity reduces the need for invasive cabling while maintaining certified performance when correctly integrated.
• Faster installation and lower labour costs:Wireless devices and SmartBracket mounting cut time on site and can reduce disruption in occupied buildings.
• Flexible layouts and retrofits:Ideal for buildings where wiring is difficult or costly — historical buildings, multi‑storey residential blocks, shopping centres, and temporary installations.
• Reduced maintenance friction:Tool‑free battery replacement and long battery life help minimise service visits.

Use cases and scenarios where the product excels

• Ideal for office floors, common corridors and amenity areas where synchronised, certified audible alarms are required but running new fire‑rated wiring would be disruptive or costly.

• Suitable for apartment blocks and halls of residence that require EN54‑grade alarms for communal areas and corridors, providing straightforward retrofitting with minimal tenant disruption.

• Wireless, battery‑powered sounders enable compliance upgrades in protected or listed buildings where channelling cable is not permitted or must be minimised.

• Events, construction site offices, and modular buildings benefit from certified alarms that can be redeployed without rewiring.

How it compares to similar products on the market

• Wireless EN54 sounders vs. wired EN54 sounders:Wired sounders remain the benchmark for maximum reliability and continuous power but require cabling that is costly and time‑consuming to install. Wireless EN54 sounders like the Ajax unit provide certified performance with much lower installation impact but rely on battery power and radio links, so they require careful site assessment and regular maintenance planning.
• Two‑way proprietary protocols vs. standard wireless:The Jeweller two‑way protocol offers supervision and confirmed delivery which can be more robust than unidirectional radio systems or consumer wireless standards. When comparing systems, evaluate link supervision, latency, and network capacity for large sites.
• Battery life and maintenance:Compared to some wireless sounders that use replaceable AA packs or integrated cells, the Ajax use of CR123A batteries provides a compact power solution with long life and simple replacement, though exact replacement intervals depend on site settings.
• Tone selection and synchronisation:The 32 selectable tones and synchronised activation give Ajax a functional parity with leading wired sounders and rival wireless products aimed at professional markets.

Customer testimonials and reviews

At the time of writing there are no verified public customer reviews included with this product brief. For real‑world feedback, installers and specifiers should consult reseller listings, installation case studies, or contact certified Ajax EN54 system partners. When selecting a device, ask for references from similar projects (size and building type) and, where possible, obtain a site demonstration of wireless link performance and synchronised alarm behaviour.

Practical installation and commissioning tips

• Perform a full site radio survey during design and commissioning to confirm Jeweller link quality in all required locations; building materials and metal partitions can reduce wireless range substantially.
• Install tamper detection and ensure SmartBracket mounting is used as specified to maintain system supervision.
• Document battery replacement schedules into maintenance contracts; although battery life is multi‑year under normal use, higher polling rates or frequent alarm activations will reduce life.
• Always integrate the sounder with compatible Ajax EN54 control equipment and follow EN54 system design guidance to ensure the overall system meets regulatory requirements.
