Fire Safety on Building Sites

Building environments, especially those in a transitional phase, present distinct fire hazards due to shifting layouts, mobile equipment, and scattered workforces. A sound alerting system is necessary for notifying workers without delay. The Howler range, including the radio-based GOLink system, HO units, and site alert models, provides a tailored 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 require no wiring.

• High sound output: Around 102 dB at a metre’s distance.


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


• IP-rated: Many are suited for outdoor use or partially exposed areas.

These alarms offer 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 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


• 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 an open-area range of around 1 km and supports multiple channels for interference avoidance.

Combining wireless and cabled systems is frequently the howler golink systems best choice for sites with varying structures.

Integrating the GOLink System

The GOLink system acts 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 components. Up to 127 points can connect across a site-wide network.

Dual-Function Features

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.

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 pop-up 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.

FAQs

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.

HO panel required?

No, HO models are self-sufficient 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.

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.

Final Notes

Whether your project involves 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 website on FireSense.
