Managing Fire Hazards on Site
Construction sites, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, mobile equipment, and scattered workforces. A reliable alerting system is necessary for notifying workers without delay. The Howler range, including the GOLink system, HO units, and site alert models, provides a scalable safety setup 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 function autonomously.
- 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 provide additional 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 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 flashing beacon for loud or noisy settings
- Ideal 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.

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
Through the Interface Unit, it’s possible to link 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 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 monitor battery levels.
- Training & signage: Ensure directions are posted and team members know how to respond to alerts.
Common Questions
- 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.
- Do HO alarms need a base station?
- No, HO models are standalone and do not require central control.
- Can GOLink interface with other site systems?
- 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.
