How Ajax alarm protection works
Ajax alarm protection works in layers. Detection starts outside and continues inside. Detectors also watch for fire and water leaks. Photo verification shows what set a device off. Instant alerts on your phone tell you what happened and where. This page explains how Ajax alarms work in a home or business. For the full device range, see our About Ajax Alarms page.

Why choose AJAX Alarms?
Comprehensive wireless security in Wrexham & Chester
We survey the property first. Then we design the system in three layers. Detection starts at the boundary and continues inside. Wireless Ajax detectors cover intrusion, smoke and heat, and water leaks. Each device reports back to the hub. Our engineers are Ajax authorised installers, so the system is set up, tested and handed over properly. That work is described on alarm installation in Wrexham and alarm installation in Chester. For CCTV, alarms and door access together, see security installers in Wrexham.


Benefits of choosing AJAX alarm systems

Layer 1
Outside Perimeter
The first layer of protection begins at the outer edges of your property. The AJAX system uses motion detectors and perimeter sensors to create a secure boundary around your premises. These devices are placed to detect unauthorised entry attempts. They alert you immediately. They also deter intruders before they reach your building. The external sensors include video imagery. That gives visual verification of any movement detected.
- Motion Detectors: Detects movement along fences and open areas.
- Perimeter Sensors with Video Imagery: Monitors gates, driveways, and entry points with visual confirmation.
Layer 2
Internal Doors, Windows, and Rooms
The second layer focuses on securing entry points and internal spaces. AJAX sensors are installed on doors, windows, and within rooms to detect any breaches. Even if an intruder bypasses the first layer, this one detects them. The alarm triggers as soon as they try to enter the building.
- Door and Window Sensors: Alerts you to unauthorised openings.
- Room Sensors: Monitors movement within the property’s interior.


Layer 3
Internal Valuable Items & Fire Detection
The third layer provides focused protection for your most valuable items. Specialist sensors and detectors are placed on specific objects such as jewellery boxes, gun cabinets, and safes. Additionally, the AJAX system integrates fire detection capabilities, offering a comprehensive safety solution.
- Item-Specific Sensors: Protects valuable possessions and secure containers.
- Fire Detectors: Monitor for smoke and heat, and raise the alarm early.
- Leak Detectors: Fitted under sinks, boilers and washing machines to catch water escapes before they cause damage.
Smartphone App
Control your alarm system at the click of a button
Ajax alarm protection is managed from the Ajax smartphone app. The app lets you monitor your property in real time. You receive instant notifications of security breaches or alarms. You can also manage the system remotely. At home, at work or on the go, you keep full control over your property’s security at your fingertips.


Visualising Ajax protection
Seeing each layer of protection
To show how the AJAX alarm system safeguards your property, we use computer-generated images. Each image illustrates one layer of protection. The images show how the system fits your property. They also show the coverage from the outside perimeter to the internal valuables. If you would rather browse the hubs, detectors and keypads, see About Ajax Alarms.
