Managing Fire Hazards on Site

Building environments, especially those in a transitional phase, present specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A reliable alerting system is necessary for ensuring all personnel are aware without delay. The Howler range, including the 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 units used where hard-wired installations are impractical. Ideal for moveable cabins or outbuildings, they function autonomously.

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


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


• Weatherproof: Many are suited for external mounting or partially exposed areas.

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

The Site-Wide Alert Range

Suitable for mid-sized 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 flashing beacon for loud or noisy settings


• Ideal where cabling is straightforward

Going Wireless: Site Alert RF

Where cable routes check here aren't possible, Site Alert RF links up to 30 units over wireless. It has an line-of-sight range of around 1 km and supports multiple frequencies for interference avoidance.

Combining wireless and cabled systems is frequently 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 connect multiple devices.

Connecting to Site Systems

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. H05 GOLink) include a first aid button alongside the fire alert. The first aid signal 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 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 check battery levels.


• Training & signage: Ensure directions are posted and team members know how to respond to alerts.

FAQs

How many devices can be wired together?

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.

HO panel required?

No, HO models are self-sufficient 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.

Will first aid alerts trigger full alarms?

No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
