Managing Fire Hazards on Site

Building environments, especially those in a transitional phase, present distinct fire hazards due to frequent layout changes, mobile equipment, and scattered workforces. A sound alerting system is necessary for ensuring all personnel are aware without delay. The Howler range, including the radio-based 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 independent, battery-operated units used where hard-wired installations are not viable. Ideal for moveable cabins or outbuildings, they require no wiring.

• High sound output: 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 main alert network may not reach.

The Site-Wide Alert Range

Suitable for compact projects, the Site Alert system can work as standalone or in groups 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 open-area range of around 1 km and supports multiple frequencies 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 acts as a coordinating hub 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 more info fire alert. The first aid signal quietly notifies the control team, 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 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.

Can both cabled and RF alarms work together?

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.
