Managing Fire Hazards on Site
Construction sites, especially those in a temporary phase, introduce distinct fire hazards due to shifting layouts, mobile equipment, and divided workforces. A reliable alerting system is necessary for ensuring all personnel are aware without delay. The Howler line-up, including the 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 offer supplementary coverage where the core 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 triggered, all devices in the network 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 line-of-sight range of around 1 km and supports multiple frequencies for interference avoidance.
Blending wireless and cabled systems is commonly the best strategy for sites with varying get more info structures.
Integrating the GOLink System
The GOLink system serves as a communication core for large, multi-zone installations, using wireless signals to connect multiple devices.
Connecting to Site Systems
Through the Interface Unit, it’s possible to link turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points can connect across a site-wide network.
Dual-Function Features
Certain models (e.g. H05 GOLink) include a first aid button alongside here 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 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.
Common Questions
- 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.
- Do HO alarms need a base station?
- 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.
- Hybrid setup compatibility?
- 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.
