Fire Safety on Building Sites
Building environments, especially those in a temporary phase, introduce specific fire hazards due to frequent layout changes, relocatable equipment, and divided workforces. A reliable alerting system is crucial for notifying workers without delay. The Howler line-up, including the radio-based 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 independent, battery-operated devices used where hard-wired installations are impractical. Ideal for portable cabins or outbuildings, they require no wiring.
- High sound output: Around 102 dB at a metre’s distance.
- Visual signal option: Some models include integrated lights for visibility.
- IP-rated: Many are suited for outdoor use or partially exposed areas.
These alarms provide supplementary coverage where the core alert network may not reach.
The Site-Wide Alert Range
Suitable for compact 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
- Recommended where cabling is straightforward
Going Wireless: Site Alert RF
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 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, check here 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 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 temporary areas.
- Set a maintenance routine: Schedule regular testing and monitor 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.
- 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 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.
- 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.
