Ajax Fire Detection
Fire safety for every site, residential or commercial
Fire can spread quickly, and early detection is vital for a safe evacuation and reduced damage. Ajax wireless fire detection systems address the limits of traditional wired setups by removing the need for cabling.
This approach allows faster installation, fewer disruptions to your property, and flexible placement of detectors. The devices identify heat, smoke, or a rapid rise in temperature, giving clear alerts when a fire begins to form.
Our team specialises in both product ranges and can help you choose a system that suits your building and its safety needs.

MotionCam Fire Verification
MotionCam Fire Verification is designed to show what triggered a fire alert without delaying your response. When heat or smoke is detected, the device can send a short, encrypted photo sequence to the control unit. This helps you confirm the cause of the alarm and understand the situation before entering the building.
MotionCam Fire Verification supports safer decision-making by giving you visual confirmation at the point of detection.
Control Through the Ajax App
The Ajax app gives you direct control of your fire detection system from your phone or tablet. You can check device status, review alerts, and adjust settings without needing to access the control unit on site.
Key features include:
- Live status for each detector

- Battery and signal checks
- Simple device testing
- Event history for review

The app lets you manage your system in a clear and structured way, giving you the information you need to act quickly when an alarm occurs.
