Wireless EN 54 Fire Alarms, Installed by GA Technical
Traditional fire alarm installations mean days of cabling, lifted floorboards, chased walls and disruption to your business. Not anymore. GA Technical now designs and installs the Ajax EN54 Line, a fully wireless, EN 54 certified fire detection and alarm system built for offices, shops, restaurants, warehouses, schools, churches and historic buildings.
Why wireless fire alarms make sense
Because every device talks to the control panel by radio, there are no cables to run between detectors, sounders and call points. That means a faster, cleaner installation, far less disruption while we work, and no damage to decor. It is especially valuable in listed and heritage properties, where running new cable can be difficult or simply not allowed.
Setup is done through Ajax's apps rather than complicated programming, and we can check on, test and maintain the system remotely, so service visits are quicker and problems are spotted early.
What's in the system
Fire Hub control panel: a touchscreen panel with clear zone and event information, LED indicators, and every communicator built in.
Smoke and heat detectors: addressable point detectors, with versions that include a built-in sounder.
Sounders and visual alarm devices: loud 100 dB sounders with 32 selectable tones, and flashing red beacons that mount on walls or ceilings.
Manual call points: press-to-alarm points that alert the whole building and can trigger evacuation actions.
I/O module: links the alarm to door locks, gates, lifts, ventilation, emergency lighting and other third-party equipment.
Range extenders: up to five per system to give solid coverage across large or complex buildings, even through steel and concrete.

Smarter detection, fewer false alarms
False alarms cost businesses time and money. The smoke detectors use a dual-spectrum optical sensor and an analysis algorithm that tells real smoke apart from steam or vapour, while the heat detectors use two thermistors to pick up both rapid temperature rises and fixed thresholds. The result is fast detection of genuine fires with far fewer nuisance call-outs.
Fire, security and CCTV in one system
The Ajax control panel is not just a fire panel. It is also certified to EN 50131 Grade 2, so the same system can run your intruder alarm, CCTV cameras and automation. When an alarm goes off, cameras can capture a photo or video to verify what is happening, helping you and your monitoring centre respond quickly and confidently. One system, one app, one point of contact.
Certified protection, installed in hours, managed from your phone.
