Powerful extensions to the EN54 series: New standards in fire detection technology
Future-proof technology for maximum safety
Ajax's EN54 line was developed specifically for commercial and municipal applications - a completely wireless fire warning and alarm system that is now complemented by innovative system enhancements. The GRAEF Group is pleased to offer its customers even more flexibility, range and security with these new products.
EN54 Fire ReX Jeweller - signal amplifier with enormous range
With the new EN54 Fire ReX Jeweller, Ajax presents a state-of-the-art wireless signal repeater that dramatically increases the range of fire alarm systems. Thanks to the Jeweller radio protocol and Ethernet connection, it can cover up to 35 km² - with up to five repeaters per system. Ideal for large properties such as shopping centers, office complexes or industrial plants.
💡 S pecial features:
- Support for fire, burglary and automation devices
- EN 54-4, EN 54-18, EN 54-25 and EN 50131 (Grade 2) certified
- 240 V~ power supply with backup battery for 24-72 hours
EN54 Internal Battery - Long-lasting power supply
Two versions of the EN54 Internal Battery are available for a reliable power supply:
24h version (7.4 V / 5 Ah)
72h version (7.4 V / 10 Ah)
These powerful Li-Ion batteries ensure continuous operation in the EN54 Fire Hub Jeweller and EN54 Fire ReX Jeweller - even in the event of a power failure.
EN54 I/O Module (2X2) Jeweller - Intelligent control of third-party devices
The new EN54 I/O Module (2X2) Jeweller significantly extends the system functionality. Two inputs and two outputs enable the integration of third-party hardware such as door controls, ventilation systems or evacuation systems.
🛠 Technical highlights:
- Wireless communication via the Jeweller protocol
- Up to 4 years battery life
- Compact, well thought-out design for easy installation
One system - infinite possibilities
With the new components, the Ajax EN54 system is more than just a fire alarm system. It becomes a central component of modern security infrastructure. GRAEF Group, as a certified Ajax partner, offers the planning, delivery and professional installation of these systems from a single source - for the highest security requirements.
What is the battery life of the internal EN54 Internal Batteries?
There are two versions: a 24-hour version with 5 Ah and a 72-hour version with 10 Ah, both of which ensure operation of the Fire Hub or ReX even in the event of a power failure.
What is the EN54 I/O Module (2×2) Jeweller used for?
The module offers two inputs and two outputs for remote integration of external systems such as door control or ventilation.
What functions are integrated in the EN54 Fire Hub Jeweller?
The Fire Hub has touchscreen control, supports up to 200 devices in 40 zones, offers wireless communication (Jeweller) and backup batteries in the event of a power failure for up to 72 hours.
Why is EN54 certification important for fire engineering systems?
EN54 certification ensures that all components comply with established European standards for fire detection technology - which is mandatory for use in public and commercial buildings.
