Fire Safety on Building Sites
Construction sites, especially those in a transitional phase, present distinct fire hazards due to shifting layouts, mobile 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 independent, battery-operated devices used where hard-wired installations are not viable. Ideal for portable cabins or outbuildings, they function autonomously.
- Loud alarm: Around 102 dB at a metre’s distance.
- Visual signal option: Some models include integrated lights for visibility.
- Weatherproof: Many are suited for outdoor use or partially exposed areas.
These alarms provide supplementary coverage where the main alert network may not reach.
The Site-Wide Alert Range
Suitable for mid-sized projects, the Site Alert system operates individually or in groups of up to 20 units using a simple two-core cable. When set off, all devices in the series respond simultaneously.
- Approx. 100 dB sound level at 1 metre
- Built-in visual LED for loud or noisy settings
- Ideal 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 line-of-sight range of around 1 km and supports multiple channels for interference avoidance.

Integrating the GOLink System
The GOLink system acts 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 tie into 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 signal 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 weekly testing and check battery levels.
- Training & signage: Ensure instructions 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.
- 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.
- 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.
Final Notes
