Detailed specifications and benefits
- EN54 family compliance:Certified to EN54‑23 for visual alarm devices and compatible with EN54‑25 requirements for system integration, making it appropriate for use in EN54 fire alarm systems and regulatory environments where compliance is mandatory.
- Visual cadence:90 ms ON / 1910 ms OFF (0.5 Hz) — the EN54‑specified temporal pattern ensures consistency across systems and clear recognition during evacuations.
- Coverage:Designed to provide a ceiling coverage of approximately 8 m diameter at a 3.0 m installation height — suitable for corridors, lobbies, classrooms and many general areas when positioned according to EN54 guidance.
- Response time:Activates within approximately 3 seconds of alarm command, delivering prompt visual notification to occupants.
- Jeweller two‑way encrypted radio:Secure communication with Ajax control and indicating equipment (CIE). Two‑way signaling reduces the risk of lost events and enables device supervision.
- Radio range:Up to 1,700 m in open space (region dependent); real‑world range will vary with building layout, materials and local RF environment.
- Frequency / power:Operates on regional bands (866–922 MHz) with ERP up to 20 mW (region dependent).
- Battery type:4 × CR123A lithium batteries are preinstalled for rapid commissioning.
- Battery life:Up to approximately 5 years under typical usage scenarios; tool‑free replacement simplifies ongoing maintenance.
- Low maintenance:Long battery life plus wireless supervision reduces routine service visits compared with frequently serviced devices.
- Ingress protection:IP54 rating — protected against dust ingress to a level suitable for many indoor and sheltered outdoor locations.
- Operating conditions:−10 °C to +50 °C and up to 80% non‑condensing humidity.
- Dimensions & weight:145 × 145 × 51 mm, approx. 509 g — compact profile supports discreet installations.
- Mounting:SmartBracket allows secure ceiling or wall mounting; tamper detection and optional tamper locking improve system integrity.
Benefits for installers, integrators and building owners
- Compliance made easier:EN54 certification simplifies approval and audit processes for fire alarm systems where EN54 is required.
- Flexible installation:Wireless communications and long battery life enable deployment where running wiring is impractical or costly.
- Reduced downtime and maintenance:Extended battery life and tool‑free replacement reduce the burden on maintenance teams.
- Inclusive alerting:High‑visibility LED flash helps ensure occupants with hearing loss or those in noisy environments receive effective alarm notification.
- Secure monitoring integration:Compatibility with common monitoring formats makes it straightforward to connect devices to central monitoring stations and CIEs.
Use cases and scenarios where the device excels
In factories, workshops, loading bays or entertainment venues where audible alarms may be masked by machinery or crowd noise, the Ajax EN54 FireProtect (VAD) Jeweller provides a fast, visible alert that meets EN54 signalling standards.
Public buildings, educational facilities, hospitals and care settings benefit from compliant visual alarms as part of an inclusive fire strategy. The device’s EN54‑compliant temporal pattern ensures recognised and consistent signalling.
When running new cabling is disruptive or prohibited, wireless VADs reduce installation impact while maintaining compliance and professional monitoring integration.
With a long radio range in open space and long battery life, the VAD is well suited to outbuildings, temporary sites or remote zones where mains power or wiring infrastructure is limited.
How it compares with other options on the market
When choosing a VAD, buyers typically weigh certification, reliability, communications, installation complexity and lifecycle cost. The Ajax EN54 FireProtect (VAD) Jeweller stands out in several ways:
- EN54 certification vs. non‑certified wireless VADs:Some wireless visual alarms are designed for security or basic notification but lack EN54 certification. For sites that require EN54‑compliant equipment, the Ajax unit removes uncertainty and simplifies regulatory compliance.
- Wireless EN54 devices vs. wired EN54 VADs:Wired VADs can offer permanent power and possibly simpler local supervision, but they require cabling and potentially higher installation costs. Ajax’s wireless option reduces installation disruption and can be more cost‑effective for retrofits or dispersed sites while still meeting EN54 signalling requirements.
- Range and supervision:Many wireless VADs trade range or supervision for low cost. The Jeweller two‑way encrypted radio provides a robust balance of long range (region dependent) and reliable supervision that commercial installers expect.
- Battery life and maintenance:With typical battery life up to ~5 years and tool‑free replacement, lifecycle costs can be lower than some wireless alternatives that need more frequent servicing.
- Ingress protection and deployment flexibility:IP54 makes the Ajax VAD flexible for indoor and sheltered outdoor use, which is an advantage over lower‑IP devices that are restricted to strictly indoor environments.
Customer feedback and installer impressions
While individual reviews vary by installation and site conditions, installers and system integrators commonly highlight the following themes in feedback about the Ajax EN54 FireProtect (VAD) Jeweller:
- Ease of installation:Technicians appreciate the SmartBracket mounting and tool‑free battery access, which speed up commissioning and routine maintenance.
- Reliable communications:The Jeweller protocol’s supervision and two‑way signalling reduce uncertainty about device status and connectivity.
- Compliance confidence:EN54 certification is repeatedly cited as a decisive factor when customers must meet regulatory standards.
- Low operating cost:Long battery life and minimal maintenance lower total cost of ownership in many deployments.
Note: prospective buyers should consult independent site‑specific reviews and speak with local installers for performance feedback in environments similar to their own.
Conclusion: why choose the Ajax EN54 FireProtect (VAD) Jeweller
The Ajax EN54 FireProtect (VAD) Jeweller is a compelling choice for projects that demand EN54‑compliant visual alarm signalling combined with the flexibility of wireless deployment. It offers a recognised EN54‑23 temporal pattern, robust two‑way encrypted communications, long battery life with easy replacement, and an IP54 rating for a range of indoor and sheltered outdoor uses. For installers, the device reduces installation time and ongoing maintenance effort; for building owners and managers, it provides compliant, reliable notification for occupants — particularly in noisy environments or where inclusive visual signalling is required.
Before purchasing or installing, verify compatibility with your control and indicating equipment (CIE), confirm monitoring formats with your monitoring station, and follow EN54 installation guidance as well as local regulations.
