Fire Safety on Building Sites

Building environments, especially those in a temporary phase, present distinct fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A sound alerting system is necessary for notifying workers without delay. The Howler range, 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 traditional systems are impractical. Ideal for portable cabins or outbuildings, they function autonomously.

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


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


• IP-rated: Many are suited for outdoor use or partially exposed areas.

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

The Site-Wide Alert Range

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

• Approx. 100 dB sound level at 1 metre


• Built-in flashing beacon for loud or noisy settings


• Ideal where cabling is straightforward

Site Alert RF (Radio-Frequency)

Where click here cable routes aren't possible, Site Alert RF links up to 30 units over wireless. It has an line-of-sight range more info of around 1 km and supports multiple channels for interference avoidance.

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

Integrating the GOLink System

The GOLink system serves as a coordinating hub for large, multi-zone installations, using wireless signals to link alarms.

Connecting to Site Systems

Through the 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 website 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 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.

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.

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.

Wrap-up

Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—deliver protection that adapt to varying conditions. For details, planning tools or live demos, refer to the Howler section on FireSense.
