Fire Safety on Building Sites

Construction sites, especially those in a transitional phase, present specific fire hazards due to shifting layouts, mobile equipment, and scattered workforces. A reliable alerting system is necessary 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 setup to match various site demands.

A Look at HO Alarms

HO alarms are self-powered, battery-operated devices used where traditional systems are not viable. Ideal for moveable 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.


• IP-rated: 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 mid-sized projects, the Site Alert system operates individually or in groups 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


• 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 more info 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 serves as a coordinating hub 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 read more components. Up to 127 points can interact across a site-wide network.

Dual-Function Features

Certain models (e.g. H05 GOLink) include website a first 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 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 temporary areas.


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


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

Common Questions

Wired capacity?

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.

Do HO alarms need a base station?

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.

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—offer solutions that adjust to varying conditions. For details, planning tools or live demos, refer to the Howler section on FireSense.
