Fire Safety on Building Sites

Building environments, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A reliable alerting system is crucial 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 scalable safety solution to match various site demands.

A Look at HO Alarms

HO alarms are self-powered, battery-operated units used where traditional systems are impractical. Ideal for moveable 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 Howler Site Alert Range

Suitable for mid-sized projects, the Site Alert system can work as standalone or in groups 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


• Recommended 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 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 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 notifies the control team, allowing medical needs to be flagged without general evacuation.

How to Deploy Effectively

• 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?

here

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.

Will first aid alerts trigger full alarms?

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

Wrap-up

Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—offer solutions that adapt to varying conditions. For product information, planning tools or live demos, refer to the Howler section on FireSense.
