EN 54 fire alarm system with AJAX
An EN 54 fire alarm system with AJAX technology provides wireless fire detection and alarm signalling for commercial premises. The detectors and sounders work together with a control panel, so alerts are displayed clearly.
RRB Security takes care of the advice, design, installation and maintenance. We tailor the solution to your premises, how they are used and the applicable requirements. If required, we provide signal transmission to an alarm receiving centre (ARC).

From advice to maintenance
Everything for your AJAX EN54 fire alarm system
One dedicated specialist, an open quote and a solution that fits your location, organisation and security needs.
Advice and design
We assess your premises, determine which detectors are needed and where, and draw up a layout of fire zones. You receive a well-founded proposal.
Installation
Thanks to the wireless connections, considerably less cabling is needed and installation is much faster than with a wired system. This keeps disruption to a minimum, including in occupied premises and listed buildings.
Remote maintenance
We monitor the technical status of the system and support its management remotely. We plan maintenance and any other work around the situation and use of your premises.
Signal transmission
If required, we set up the link to an ARC to receive fire and fault alerts. The connections and follow-up are set up in line with the agreements made.

Advice
What should you look for in a fire alarm system?
The right fire alarm system starts with an assessment of your premises and the applicable requirements. We include the topics below in our advice.
When should you choose EN 54?
EN 54 is the European series of standards for components of fire detection and fire alarm systems. According to AJAX, the control panel and the components of the EN54 line meet these standards. For commercial buildings, that is an important difference from consumer detectors, which are not tested against that standard.
Mandatory fire alarm system and NEN 2535
If a fire alarm system is mandatory for your building, for example under the environmental permit (omgevingsvergunning) or the Dutch Building Works (Living Environment) Decree (Besluit bouwwerken leefomgeving), the Netherlands requires compliance with NEN 2535, the Dutch standard for fire alarm systems, and often certification. This is assessed per building. Together with you, we look at whether the AJAX EN54 fire alarm system suits your situation, or which route is needed.
Wireless or wired
Wireless connections reduce cabling work and allow faster installation. We assess which version suits your premises and take any future extensions into account.
Range and range extenders
We assess the wireless range within your premises. Where the size or construction calls for it, we include range extenders in the design.
Batteries and maintenance
The system monitors the battery status and operation of the detectors. We plan checks and replacements based on the alerts, the usage and the maintenance needs.
Signal transmission to the ARC
A link to an ARC means fire and fault alerts are received and followed up. We advise on the connections and record the required follow-up in agreements.
Fire zones and evacuation
Dividing the building into fire zones helps to identify where an alert comes from. We match the audible and visual alarm signalling to the premises and the evacuation arrangements.
Integration with intruder alarms and CCTV
The AJAX platform lets you manage fire detection, intruder alarms and camera footage together. We advise on the combination that suits your situation. Read more on AJAX alarm system and Camera security.
Frequently asked questions
Frequently asked questions about the AJAX EN54 fire alarm system
Can't find your question? Our specialists are happy to help with advice that fits your situation.
What is the difference between the AJAX EN54 line and the AJAX FireProtect 2?
The FireProtect 2 is designed for smoke and heat detection within an AJAX alarm system for homes. The EN54 line is a fire alarm system for commercial premises, with its own control panel and components that, according to AJAX, meet the EN 54 standards. We advise on the solution that suits your situation.
Is the AJAX EN54 fire alarm system wireless?
The detectors and sounders communicate wirelessly and run on batteries. The control panel and any range extenders need mains power and have a backup battery.
How many detectors can I connect?
One EN54 Fire Hub supports up to 200 devices, spread over 40 fire zones.
How long do the batteries last?
Battery life varies by component and usage. The system alerts you when a replacement is needed. The product specifications give an indication of battery life.
Can the system transmit alerts to an ARC?
Yes, the system can be linked to an alarm receiving centre. We tailor the connections and the follow-up of alerts to your situation.
Can I extend the system with intruder alarms and CCTV?
The AJAX platform offers ways to combine these functions. We assess which extension fits your premises and your existing security.
