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 line-up, including the radio-based GOLink system, HO units, and site alert models, provides a scalable safety solution to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated units used where hard-wired installations are impractical. Ideal for portable cabins or outbuildings, they require no wiring.
- Loud alarm: 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 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
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 read more and cabled systems is commonly 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 check here the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and howler site alert systems other site safety components. Up to 127 points can connect 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 pop-up 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
- 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.
- 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.
