EN54 Line: Ajax Systems revolutionizes fire safety with a completely wireless EN 54 product line

With its new EN54 Line product range, Ajax Systems presents one of the most significant innovations in professional fire protection in recent years. For the first time, a completely wireless, EN 54-certified commercial fire alarm system is coming onto the market—a technological leap that greatly simplifies installation while meeting the highest standards.

For the GRAEF Group, as a certified specialist installer, this solution opens up new opportunities to implement demanding fire protection projects more quickly, flexibly, and efficiently.

EN54 Fire Hub Jeweller – the heart of the new wireless fire alarm system

At the heart of the system is the EN54 Fire Hub Jeweller —a modern fire alarm control panel with a touchscreen, intuitive user interface, and complete wireless architecture.

The most important features:

• Completely wireless fire alarm technology in accordance with EN 54
• Certified according to EN 54 and EN 50131 (Grade 2)
• Management of up to 200 addressable devices
• Structuring into 40 zones
• Integrated communicators for reliable alarm transmission
• Support for fire protection, burglary protection, and video surveillance

This is the first time that the system combines several safety-related disciplines in a completely wireless platform.

EN 54-certified detectors and signaling devices – design meets precision

The new product line includes a complete range of EN 54-certified components:

• automatic fire detectors
• acoustic signal generators
• optical signal transmitters
• manual push-button alarms
• wireless signal booster
• Input/output modules

Each device follows the typical Ajax design approach: sleek, modern, unobtrusive—yet technically extremely powerful and optimized for fast detection, strong alarms, and minimal maintenance.

Intelligent radio architecture – powerful, scalable, interference-free

The EN54 Line is based on proven Jeweller radio technology, which has been reinforced with additional security mechanisms. This enables the system to achieve:

• High range even in complex buildings

• Short response time in case of alarm

• robust anti-sabotage protection

• Stable operation even in densely built-up areas

Signal amplifiers and expansion modules enable flexible system architectures – ideal for multi-story properties, industrial facilities, or buildings in need of renovation without existing infrastructure.

Installation in hours instead of days

A key advantage of the new line is the drastically reduced installation time.
According to Ajax partners, projects are made possible thanks to:

• complete radio architecture,

• intuitive touch operation,

• lack of programming phases,

• automatic device detection

• as well as professional control via native apps

Realized in hours instead of days.

For the GRAEF Group, this means faster project implementation, less disruption to the building structure, and high cost-effectiveness for both new installations and modernizations.
