Fire Safety on Building Sites
Construction sites, especially those in a transitional phase, present specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A sound alerting system is crucial for ensuring all personnel are aware 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 self-powered, battery-operated units used where traditional systems are not viable. Ideal for portable cabins or outbuildings, they function autonomously.
- 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 additional coverage where the main alert network may not reach.
The Howler Site 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 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
Going Wireless: Site Alert RF
Where cable routes aren't possible, 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 strategy 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 connect multiple devices.
Connecting to Site Systems
Through the click here Interface Unit, it’s possible to tie into 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.
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 monitor battery levels.
- Training & signage: Ensure directions are posted and team members know how to respond to alerts.
FAQs
- 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.
- Why use an alarmed switch cover?
- It reduces false alarms by sounding a warning if tampered with before activation.
- Hybrid setup compatibility?
- 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.
