Managing Fire Hazards on Site
Construction sites, especially those in a temporary phase, introduce specific fire hazards due to frequent layout changes, mobile equipment, and scattered workforces. A sound alerting system is crucial for ensuring all personnel are aware without delay. The Howler range, including the radio-based GOLink system, HO units, and site alert models, provides a tailored safety setup to match various site demands.
A Look at HO Alarms
HO alarms are independent, battery-operated units used where traditional systems are not viable. 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.
- IP-rated: Many are suited for outdoor use or partially exposed areas.
These alarms offer additional coverage where the main alert network may not reach.
The Site-Wide 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 flashing beacon 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 open-area range of around 1 km and supports multiple channels for interference avoidance.
Combining wireless and cabled systems is frequently the best choice for sites with varying structures.
Integrating the GOLink System
The GOLink system serves as a click here communication core for large, multi-zone installations, using wireless signals to connect multiple devices.
Connecting to Site Systems
Through the Interface Unit, click here 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 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 pop-up areas.
- Set a maintenance routine: Schedule regular testing and check battery levels.
- Training & signage: Ensure instructions 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.
- 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.
Wrap-up
Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—offer solutions that adjust to varying click here conditions. For details, planning tools or live demos, refer to the Howler section on FireSense.
