Managing Fire Hazards on Site

Building environments, especially those in a temporary phase, introduce specific fire hazards due to frequent layout changes, mobile equipment, and scattered workforces. A sound alerting system is necessary for notifying workers without delay. The Howler line-up, including the GOLink system, HO units, and site alert models, provides a scalable safety solution to match various site demands.

A Look at HO Alarms

HO alarms are independent, battery-operated devices 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.


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


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

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

The Howler Site Alert Range

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

• Approx. 100 dB sound level at 1 metre


• Built-in visual LED for loud or noisy settings


• Ideal 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 website an line-of-sight range of around 1 km and supports multiple frequencies for interference avoidance.

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

Integrating the GOLink System

The GOLink system serves 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. Up to 127 points can interact across a site-wide network.

First Aid Callouts

Certain models (e.g. H05 GOLink) include a first check here aid button alongside the fire alert. The first aid function quietly notifies the control team, allowing medical needs to be flagged without general evacuation.

Deployment Guidelines

• 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 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.

What’s the wireless range of Site Alert RF?

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

Do HO alarms need a base station?

No, HO models are standalone 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.

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.
