Managing Fire Hazards on Site

Building environments, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A sound alerting system is necessary for ensuring all personnel are aware without delay. The Howler range, including the 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 impractical. Ideal for portable cabins or outbuildings, they require no wiring.

• High sound output: Around 102 dB at a metre’s distance.


• Optional strobe: Some models include integrated lights for visibility.


• IP-rated: 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 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


• Ideal where cabling is straightforward

Site Alert RF (Radio-Frequency)

Where cable routes aren't possible, Site Alert RF links up to click here 30 units over wireless. It has an line-of-sight range of around 1 km and supports multiple frequencies 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 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 interact across a site-wide network.

Dual-Function Features

Certain website 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 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 pop-up 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.

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 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.

Wrap-up

Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—offer solutions that adapt to varying conditions. For details, planning tools or live demos, refer to the Howler section on FireSense.
