Managing Fire Hazards on Site
Construction sites, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A reliable alerting system is crucial for notifying workers without delay. The Howler range, including the radio-based GOLink system, HO units, and site alert models, provides a scalable safety setup to match various site demands.
A Look at HO Alarms
HO alarms are independent, battery-operated devices used where traditional systems are not viable. 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.
- Weatherproof: Many are suited for external mounting or partially exposed areas.
These alarms offer supplementary coverage where the core alert network may not reach.
The Site-Wide Alert Range
Suitable for mid-sized 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
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.
Combining wireless and cabled systems is commonly the best strategy for sites with varying structures.
Integrating the GOLink System
The GOLink system acts 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 click here 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 signal quietly notifies the control team, allowing medical needs to be flagged without general evacuation.
Deployment Guidelines
- Zone assessment: Identify where alarms need to be noticeable, 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 weekly testing and check 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.
