Managing Fire Hazards on Site
Building environments, especially those in a temporary phase, present specific fire hazards due to shifting layouts, mobile equipment, and divided workforces. A sound 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 setup 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 require no wiring.
- High sound output: 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 additional coverage where the main alert network may not reach.
The Howler Site Alert Range
Suitable for mid-sized 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 flashing beacon for loud or noisy settings
- Recommended where cabling is straightforward
Site Alert RF (Radio-Frequency)
Where cabling is limited, website 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 commonly the best choice 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 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 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 regular 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.
- 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 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.
- 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.
- Will first aid alerts trigger full alarms?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
