Managing Fire Hazards on Site
Building environments, especially those in a transitional phase, introduce distinct fire hazards due to shifting layouts, mobile equipment, and scattered workforces. A reliable alerting system is crucial for notifying workers without delay. The Howler range, including the radio-based GOLink system, HO units, and site alert models, provides a scalable safety solution to match various site demands.
What Exactly Are HO Alarms?
HO alarms are self-powered, 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.
- 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 Howler Site Alert Range
Suitable for mid-sized projects, the Site Alert system operates individually 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 frequently the best choice for sites with varying structures.
Integrating the GOLink System
The GOLink 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 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 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 temporary areas.
- Set a maintenance routine: Schedule regular testing and monitor 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.
- 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 standalone 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.
- Will first aid alerts trigger full alarms?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
