Fire Safety on Building Sites
Construction sites, especially those in a temporary phase, introduce distinct fire hazards due to shifting layouts, relocatable equipment, and divided workforces. A sound alerting system is crucial for ensuring all personnel are aware without delay. The Howler range, including the 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 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.
- Optional strobe: Some models include integrated lights for visibility.
- Weatherproof: Many are suited for outdoor use or partially exposed areas.
These alarms offer 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 groups of up to 20 units using a simple two-core cable. When triggered, 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
Site Alert RF (Radio-Frequency)
Where cabling is limited, 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 frequently the best strategy for sites with varying get more info structures.
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.
First Aid Callouts
Certain models (e.g. H05 GOLink) include a first aid button alongside the fire alert. The first aid here 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 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.
- 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.
- Will first aid alerts trigger full alarms?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
