Fire Safety on Building Sites
Building environments, especially those in a transitional phase, present specific fire hazards due to frequent layout changes, mobile equipment, and scattered 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 setup to match various site demands.
What Exactly Are HO Alarms?
HO alarms are self-powered, battery-operated units used where traditional systems are impractical. Ideal for moveable 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 external mounting or partially exposed areas.
These alarms provide additional coverage where the core alert network may not reach.
The Site-Wide Alert Range
Suitable for compact projects, the Site Alert system can work as standalone or in linked setups 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 get more info 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.
Blending wireless and cabled systems is frequently the best choice 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
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 check here 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 weekly 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 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.
- Can both cabled and RF alarms work together?
- 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.
