Fire Safety on Building Sites

Construction sites, especially those in a transitional phase, present distinct fire hazards due to shifting layouts, relocatable equipment, and divided workforces. A reliable alerting system is crucial for ensuring all personnel are aware without delay. The Howler line-up, including the GOLink system, HO units, and site alert models, provides a scalable safety solution to match various site demands.

A Look at HO Alarms

HO alarms are independent, battery-operated devices used where traditional systems are not viable. Ideal for moveable cabins or outbuildings, they require no wiring.

• Loud alarm: Around 102 dB at a metre’s distance.


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


• IP-rated: Many are suited for external mounting or partially exposed areas.

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

The Site-Wide Alert Range

Suitable for compact 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


• Recommended where cabling is straightforward

Going Wireless: Site Alert RF

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 channels for interference avoidance.

Combining wireless and cabled systems is commonly the best strategy for sites with varying structures.

Integrating the GOLink System

The GOLink system serves as a coordinating hub for large, multi-zone installations, using wireless signals to link alarms.

GOLink Interface Connections

Dual-Function Features

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 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 regular testing and monitor 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.

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.

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—deliver protection that adapt to varying conditions. For product information, planning tools or live demos, refer to the Howler section on FireSense.
