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 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 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.


• IP-rated: 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

Site Alert RF (Radio-Frequency)

Where cabling is limited, Site Alert RF links up to 30 units over wireless. It more info has an line-of-sight range of around 1 km and supports multiple frequencies for interference avoidance.

Blending 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 link read more alarms.

GOLink Interface Connections

Through the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points can interact 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 temporary areas.


• Set a maintenance routine: Schedule weekly 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.

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.

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.
