Managing Fire Hazards on Site

Construction sites, especially those in a temporary phase, present distinct fire hazards due to frequent layout changes, relocatable equipment, and divided workforces. A sound alerting system is necessary for ensuring all personnel are aware 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 self-powered, battery-operated devices used where traditional systems are impractical. 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.


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

These alarms provide supplementary 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 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 website around 1 km and supports multiple channels for interference avoidance.

Combining 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 wireless signals to link alarms.

Connecting to Site Systems

Through the Interface Unit, it’s possible to link turnstiles, autodiallers, CCTV, and other site safety components. click here Up to 127 points can interact across a site-wide network.

First Aid Callouts

Certain models (e.g. H05 GOLink) include a read more 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 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 directions are posted and team members know how to respond to alerts.

FAQs

Wired capacity?

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.

Is third-party integration supported?

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.

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.

Final Notes

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