What's in the System?

Every component is wireless, battery-powered, and purpose-built for temporary environments. The units form a self-linking mesh — install them, and they find each other.

Installation Process

We Install It for You — How It Works

Step: We Plan Your Coverage

We Plan Your Coverage

Our engineer assesses your site layout and identifies the key detection and alerting areas. We produce a coverage plan before a single unit goes up.

Step: We Install & Link the Units

We Install & Link the Units

Battery-powered devices are installed and automatically form a wireless mesh network — no cabling, no building works, no disruption to your programme.

Step: The System Reacts Instantly

The System Reacts Instantly

When a detector or call point activates, all units across the site flash, sound, and announce the alert simultaneously. No zones missed.

Step: Always Connected

Always Connected

The mesh network constantly self-monitors. If a unit loses connection, the system flags it immediately — keeping you covered even as the site evolves.

Frequently Asked Questions

How quickly can the system be deployed?

Our wireless, battery-powered units can be installed and operational in minutes. No cabling, no mains power, and no building works are required. Most sites are covered within a single day.

What sites is this system suitable for?

The system is designed for temporary protection on construction sites, demolition sites, road works, and vacant properties — anywhere that needs immediate, reliable fire detection without a permanent infrastructure.

What happens when one unit triggers?

All units across the site simultaneously flash, sound, and broadcast a spoken announcement. There are no zones to miss and no delays — the entire mesh activates within seconds.

What does IP66 rated mean?

IP66 means the units are fully protected against dust ingress and powerful water jets — making them suitable for outdoor use and the harsh, variable conditions found on construction and demolition sites.

How long do the batteries last?

The Emergency Fire & First Aid Sounder Beacon units have a two-year battery life, covering the typical duration of most construction projects without the need for mains power or battery replacement.

Can the system be reconfigured as the site develops?

Yes. Because units communicate via a self-forming wireless mesh, you can add, remove, or reposition units as your site changes — floors are added, areas are enclosed, or welfare arrangements move.
