Fire Safety on Building Sites

Building environments, especially those in a transitional phase, introduce specific fire hazards due to frequent layout changes, mobile equipment, and divided workforces. A reliable 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 tailored safety setup to match various site demands.

What Exactly Are HO Alarms?

HO alarms are independent, battery-operated units used where traditional systems are impractical. Ideal for portable 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 offer additional coverage where the core alert network may not reach.

The Howler Site 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 series respond simultaneously.

• Approx. 100 dB sound level at 1 metre


• Built-in flashing beacon for loud or noisy settings


• Recommended 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 frequencies for interference avoidance.

Blending wireless and cabled systems is commonly the best strategy 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. 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 fire alert. The first aid signal quietly notifies the more info control team, 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 pop-up areas.


• Set a maintenance routine: Schedule regular testing and check battery levels.


• Training & signage: Ensure instructions 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.

How far does the wireless version reach?

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.

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.

Does first aid signal cause evacuation?

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