Fire Safety on Building Sites

Building environments, especially those in a temporary phase, present distinct fire hazards due to shifting layouts, relocatable equipment, and divided workforces. A reliable alerting system is crucial for ensuring all personnel are aware without delay. The Howler range, including the GOLink system, HO units, and site alert models, provides a tailored safety solution 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 moveable cabins or outbuildings, they function autonomously.

• High sound output: Around 102 dB at a metre’s distance.


• Visual signal option: Some models include integrated lights for visibility.


• Weatherproof: Many are suited for outdoor use or partially exposed areas.

These alarms provide additional coverage where the core alert network may not reach.

The Site-Wide Alert Range

Suitable for compact projects, the Site Alert system operates individually or in linked setups of up to 20 units using a simple two-core cable. When set off, all devices in check here 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

Site Alert RF (Radio-Frequency)

Where cabling is limited, Site Alert RF links up to 30 units over wireless. It has an open-area range of around 1 km and supports multiple channels for interference avoidance.

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

Integrating the GOLink System

The GOLink system acts as a communication core for large, multi-zone installations, using wireless signals to connect multiple devices.

Connecting to Site Systems

Through the Interface Unit, it’s possible to link turnstiles, autodiallers, CCTV, and other site safety components. howler golink systems Up to 127 points can connect 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 signal quietly notifies more info the control team, allowing medical needs to be flagged without general evacuation.

How to Deploy Effectively

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


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


• Set a maintenance routine: Schedule weekly testing and check battery levels.


• Training & signage: Ensure instructions 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.

Is third-party integration supported?

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

Purpose of switch protection?

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

Hybrid setup compatibility?

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

Does first aid signal cause evacuation?

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