Ajax EN54 Internal Battery (72H) – Rechargeable Backup Battery
The Ajax EN54 Internal Battery (72H) is a rechargeable Li-ion backup battery specifically engineered for the EN54 Fire Hub Jeweller and EN54 Fire ReX Jeweller. Certified to EN 54-4 standards, it ensures your Ajax fire alarm system continues to operate for up to 72 hours during a mains power outage – maintaining full fire protection when it matters most.
Reliable Backup Power
Built with Li-ion 18650 cell technology, this 7.4 V / 10 Ah battery delivers stable, reliable power output throughout its discharge cycle. EN 54-4 certification confirms it meets the stringent requirements for backup power supplies in commercial fire detection and alarm systems, ensuring regulatory compliance for installations across the UK and Europe.
Hot-Swappable Design
The battery can be replaced while the EN54 Fire Hub or Fire ReX is running – no need to power down the fire system during maintenance. This ensures zero interruption to fire protection, which is critical for occupied commercial premises. Installation is plug-and-play: simply insert the battery into the designated compartment and it's ready to operate with no configuration required.
Intelligent Monitoring
Battery charge level is continuously monitored and displayed in the Ajax apps and on the CIE interface (in 1% increments). Low-charge notifications are sent well in advance via push notifications, giving maintenance teams plenty of time to schedule replacement.
Colour-Matched
Available in White or Black to match the colour of your EN54 Fire Hub Jeweller or EN54 Fire ReX Jeweller.
