Fire Safety on Building Sites
Construction sites, especially those in a temporary phase, present specific fire hazards due to frequent layout changes, 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 devices used where traditional systems are impractical. Ideal for moveable 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 outdoor use or partially exposed areas.
These alarms provide 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 groups of up to 20 units using a simple two-core cable. When triggered, all devices in the series 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 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 get more info multiple frequencies 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 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 turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points can connect across a site-wide network.
First Aid Callouts
Certain models (e.g. H05 click here GOLink) include a first aid button alongside the fire alert. The first aid signal quietly notifies the control team, check here allowing medical needs to be flagged without general evacuation.
How to Deploy Effectively
- 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 pop-up areas.
- Set a maintenance routine: Schedule regular testing and check 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.
- Purpose of switch protection?
- 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.
Final Notes
Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—deliver protection that adapt to varying conditions. For product information, planning tools or live demos, refer to the Howler section on FireSense.
