Fire Safety on Building Sites

Construction sites, especially those in a temporary phase, present specific fire hazards due to frequent layout changes, relocatable equipment, and divided workforces. A sound alerting system is necessary for ensuring all personnel are aware without delay. The Howler line-up, including the GOLink system, HO units, and site alert models, provides a tailored safety setup to match various site demands.

A Look at HO Alarms

HO alarms are independent, battery-operated units used where hard-wired installations are not viable. Ideal for portable cabins or outbuildings, they function autonomously.

• Loud alarm: Around 102 dB at a metre’s distance.


• Optional strobe: Some models include integrated lights for visibility.


• Weatherproof: Many are suited for external mounting or partially exposed areas.

These alarms offer additional coverage where the main alert network may not reach.

The Site-Wide Alert Range

Suitable for compact projects, the Site Alert system can work as standalone or in groups of up to 20 units using a simple two-core cable. When set off, all devices in the network respond simultaneously.

• Approx. 100 dB sound level at 1 metre


• Built-in flashing beacon for loud or noisy settings


• Recommended where cabling is straightforward

Going Wireless: Site Alert RF

Where cable routes aren't possible, Site Alert RF links up to 30 units over wireless. It has an open-area range of around 1 km and supports multiple frequencies for interference avoidance.

Combining wireless and cabled systems is frequently the best strategy for sites with varying structures.

Integrating the GOLink System

The GOLink system acts howler site alarms as a coordinating hub for large, multi-zone installations, using wireless signals to connect multiple devices.

GOLink Interface Connections

Through the website Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points can interact across a site-wide network.

First Aid Callouts

Certain models (e.g. H05 GOLink) include a first aid button alongside the fire alert. The first aid function quietly sends a location-specific assistance request, allowing medical needs to be flagged without general evacuation.

How to Deploy Effectively

• Zone assessment: Identify where alarms need to be noticeable, dividing the site into manageable sectors.


• Choose connection types wisely: Use hard-wired alarms where feasible, supplementing with RF in distant or temporary areas.


• Set a maintenance routine: Schedule regular testing and monitor battery levels.


• Training & signage: Ensure directions are posted and team members know how to respond to alerts.

Common Questions

How many devices can be wired together?

Up to 20 Site Alert units can be connected using 2-core cable.

How far does the wireless version reach?

Approx. 1 km in open-air conditions, though physical obstructions can reduce range.

HO panel required?

No, HO models are self-sufficient and do not require central control.

Can GOLink interface with other site systems?

Yes, external systems can be connected via the GOLink Interface Unit.

Why use an alarmed switch cover?

It reduces false alarms by sounding a warning if tampered with before activation.

Can both cabled and RF alarms work together?

Yes, the GOLink system allows wired and wireless units to operate on the same network.

Will first aid alerts trigger full alarms?

No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
