Fire Safety on Building Sites
Construction sites, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A sound 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 tailored safety solution to match various site demands.
A Look at HO Alarms
HO alarms are self-powered, battery-operated devices used where traditional systems are impractical. 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.
- Weatherproof: Many are suited for external mounting or partially exposed areas.
These alarms provide additional coverage where the main 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

Site Alert RF (Radio-Frequency)
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 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 connect multiple devices.
Connecting to Site Systems
Through the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety components. check here 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 function quietly sends a location-specific assistance request, 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.
FAQs
- Wired capacity?
- 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.
- 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.
- 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 adjust to varying conditions. For details, planning tools or live demos, refer to the Howler section on FireSense.
