You need a fire alarm system if the building regulations require one for your building, and in that case the components must be certified to EN 54. Ajax has its own EN54 range for this: a wireless, addressable fire alarm system with the Fire Hub as the control panel. Because no cables need to be run, it is particularly suitable for existing buildings. In this article you can read what EN 54 means, what the system consists of and how to approach a project.
Ajax EN54 in four points
Wireless
Detectors and sirens communicate wirelessly with the control panel, with no cabling through the building.
Addressable
Every detector has its own address, so when an alarm is raised you can see exactly where it is.
Fire Hub
The control panel with a 10.1 inch touchscreen manages up to 200 devices in up to 40 fire zones.
Backup power
With an internal battery the control panel and repeaters keep working for 24 or 72 hours during a power cut.
Smoke detectors or a fire alarm system?
These are two different things. In an ordinary home smoke detectors are mandatory, and standalone detectors such as the Ajax FireProtect 2 are sufficient. A fire alarm system is a complete system with a control panel, and it is only mandatory if the building regulations require it for a building.
| Smoke detectors | Fire alarm system | |
|---|---|---|
| Where | Homes | Buildings where the building regulations require a fire alarm system |
| Regulations | Smoke detector requirement, installation in accordance with NEN 2555 | Besluit bouwwerken leefomgeving (Dutch Building Activities Decree), design in accordance with NEN 2535 |
| Components | Standalone smoke detectors, interlinked if required | Control panel, detectors, manual call points and sounders with EN 54 certification |
| At Ajax | FireProtect 2 | The EN54 range with the Fire Hub |
Good to know whether your building needs a fire alarm system and how extensive it must be is stated in the environmental permit, or follows from the use and size of the building. If you are unsure, check with your municipality, a fire safety consultant or an installer of fire alarm systems before you choose components. You can read more about smoke detectors in the home in our article on smoke detectors and NEN 2555.

What do the numbers mean? EN 54 is a series of European standards, with a separate part for each type of component. Part 2 covers the control panel, part 7 smoke detectors, parts 3 and 23 sound and light, and part 25 wireless connections. The prices are live from our webshop.
Why wireless is attractive
No chasing or breaking out
In an existing building you do not have to run cables through ceilings and walls. That saves time, disruption and repair work.
Knowing exactly where
Because every device is addressable, the control panel shows which detector it is and in which zone when an alarm is raised.
Supervised connection
The connection between devices and control panel is monitored continuously, as EN 54-25 requires for wireless components.
How to approach an EN54 project
1. Determine the requirements
Determine which system your building needs, together with your municipality or a fire safety consultant.
2. Create a design
Record where the detectors, manual call points and sounders will go, in accordance with NEN 2535.
3. Order the components
Build the components from the design in our EN54 configurator and order them from us.
4. Install and hand over
This is done by an installer who fits fire alarm systems. After installation each zone is tested and a certificate is mandatory, followed by an inspection by an independent body.

More about Ajax
You can read everything about the system on one page at Ajax alarm system. These articles go into more depth on one component. You can find all articles under Ajax Systems.
Building your EN54 system
Secures is an official Ajax PRO partner and supplies the complete Ajax EN54 range. We do not carry out the design, installation or handover for EN54; for that you engage an installer of fire alarm systems. Once you have the list of components, build it in the configurator, or request a quotation for the products.
