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 GOLink system, HO units, and site alert models, provides a scalable safety setup to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated units used where hard-wired installations are not viable. Ideal for portable cabins or outbuildings, they function autonomously.
- High sound output: Around 102 dB at a metre’s distance.
- Optional strobe: Some models include integrated lights for visibility.
- Weatherproof: Many are suited for external mounting or partially exposed areas.
These alarms provide supplementary coverage where the core 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 groups 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 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 website system acts as a coordinating hub for large, multi-zone installations, using wireless signals to connect multiple devices.
Connecting to Site Systems
Through the Interface Unit, it’s possible to link turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points get more info 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 signal quietly sends a location-specific assistance request, 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.
- 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.
- Will first aid alerts trigger full alarms?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
