Managing Fire Hazards on Site
Construction sites, especially those in a temporary phase, present distinct fire hazards due to frequent layout changes, mobile 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 self-powered, 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.
- Optional strobe: Some models include integrated lights for visibility.
- IP-rated: Many are suited for external mounting or partially exposed areas.
These alarms provide supplementary coverage where the core alert network may not reach.
The Howler Site Alert Range
Suitable for mid-sized projects, the Site Alert system operates individually 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 visual LED for loud or noisy settings
- Ideal 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 line-of-sight range of around 1 km and supports multiple channels for interference avoidance.
Combining wireless and cabled systems is frequently the best strategy for sites with varying 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.
GOLink Interface Connections
Through the Interface Unit, it’s possible to tie into read more 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 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
- How many devices can be wired together?
- 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 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.
- Purpose of switch protection?
- 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.
