Managing Fire Hazards on Site
Building environments, especially those in a temporary phase, introduce distinct fire hazards due to shifting layouts, mobile equipment, and divided workforces. A reliable alerting system is necessary for notifying workers without delay. The Howler range, including the radio-based 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 devices used where hard-wired installations are impractical. Ideal for moveable cabins or outbuildings, they require no wiring.
- Loud alarm: 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 offer additional coverage where the main alert network may not reach.
The Howler Site 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 series respond simultaneously.
- Approx. 100 dB sound level at 1 metre
- Built-in visual LED for loud or noisy settings
- Recommended where cabling is straightforward
Site Alert RF (Radio-Frequency)
Where cable routes aren't possible, 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.
Blending wireless and cabled systems is frequently the best choice for sites with varying structures.
Integrating the GOLink System
The GOLink system serves as a coordinating hub for large, multi-zone installations, using wireless signals to link alarms.
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. The first aid signal quietly notifies the control team, howler golink systems 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.
Common Questions
- 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.
- Do HO alarms need a base station?
- 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.
- 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.
