Fire Safety on Building Sites

Construction sites, especially those in a temporary phase, present distinct fire hazards due to frequent layout changes, mobile equipment, and scattered workforces. A sound 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 scalable safety solution to match various site demands.

What Exactly Are HO Alarms?

HO alarms are self-powered, battery-operated devices 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.


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


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

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

The Howler Site Alert Range

Suitable for mid-sized 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 the network respond simultaneously.

• Approx. 100 dB sound level at 1 metre


• Built-in visual LED for loud or noisy settings


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

Blending wireless and cabled systems is commonly the best choice for read more 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.

GOLink Interface Connections

Through the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety components. 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 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 temporary areas.


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

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.

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.

Wrap-up

Whether your project involves check here one zone or several, Howler alarms—HO, GOLink, and Site Alert—deliver protection that adjust to varying conditions. For product information, planning tools or live demos, visit the Howler section on FireSense.
