Fire Safety on Building Sites

Construction sites, especially those in a temporary phase, present specific fire hazards due to frequent layout changes, relocatable equipment, and scattered workforces. A sound alerting system is crucial for notifying workers without delay. The Howler line-up, including the radio-based 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 independent, battery-operated units used where hard-wired installations are impractical. Ideal for portable cabins or outbuildings, they require no wiring.

• 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 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 triggered, all devices in the network respond simultaneously.

• Approx. 100 dB sound level at 1 metre


• Built-in visual LED for loud or noisy settings


• Recommended where cabling is straightforward

Going Wireless: Site Alert RF

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 sites with varying structures.

Integrating the GOLink System

The GOLink system serves as a communication core for large, multi-zone installations, using get more info wireless signals to link alarms.

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 interact across a site-wide network.

First Aid Callouts

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

How to Deploy Effectively

• 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 pop-up 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

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 standalone and do not require central control.

Is third-party integration supported?

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.
