Managing Fire Hazards on Site
Building environments, especially those in a transitional phase, present specific fire hazards due to frequent layout changes, relocatable equipment, and divided workforces. A sound alerting system is necessary 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 setup to match various site demands.
A Look at HO Alarms
HO alarms are independent, battery-operated devices used where hard-wired installations are not viable. Ideal for portable cabins or outbuildings, they function autonomously.
- Loud alarm: Around 102 dB at a metre’s distance.
- Optional strobe: Some models include integrated lights for visibility.
- Weatherproof: Many are suited for outdoor use or partially exposed areas.
These alarms offer supplementary coverage where the main alert network may not reach.
The Site-Wide Alert Range
Suitable for compact 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
- Recommended where cabling is straightforward
Going Wireless: Site Alert RF
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 frequencies 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 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 interact across a site-wide network.
First Aid Callouts
Certain models (e.g. H05 GOLink) include a first aid button alongside the fire alert. get more info The first aid function quietly sends a location-specific assistance request, 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 regular 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.
- What’s the wireless range of Site Alert RF?
- 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.
- Is third-party integration supported?
- 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.
