Fire Safety on Building Sites
Construction sites, especially those in a transitional phase, introduce distinct fire hazards due to frequent layout changes, relocatable equipment, and scattered workforces. A reliable alerting system is crucial for notifying workers without delay. The Howler range, including the GOLink system, HO units, and site alert models, provides a tailored safety solution to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated units used where hard-wired installations are impractical. Ideal for moveable cabins or outbuildings, they require no wiring.
- Loud alarm: Around 102 dB at a metre’s distance.
- Optional strobe: Some models include integrated lights for visibility.
- IP-rated: Many are suited for external mounting or partially exposed areas.
These alarms offer supplementary coverage where the main alert network may not reach.
The Howler Site 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 set off, all devices in the network respond simultaneously.
- Approx. 100 dB sound level at 1 metre
- Built-in flashing beacon for loud or noisy settings
- Recommended 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 open-area range of around 1 km and supports multiple frequencies for interference avoidance.
Combining wireless and cabled systems is frequently the best choice for sites with varying structures.
Integrating the GOLink System
The GOLink system acts as a communication core for large, multi-zone installations, using wireless signals to link alarms.
GOLink Interface Connections
Through the Interface Unit, it’s possible website 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 function quietly sends a location-specific assistance request, allowing medical needs to be flagged without general evacuation.
Deployment Guidelines
- 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 check 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.
- 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.
- Purpose of switch protection?
- 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.
