The Importance of Howler Systems in Fire Safety

Construction and temporary sites present unique fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm setup is vital for promptly alerting everyone in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a scalable, adaptable solution suitable for diverse environments.

Overview of HO Alarms?

HO alarms are self-contained, standalone units intended for mobile spaces such as portable offices or unconnected site areas. No hard-wired connection is required, making installation simple.

• High output: Typically 102 dB at 1 metre.


• Visual indicators: Available units feature a strobe light alongside the audible siren.


• Durable casing: Many are IP-rated for outdoor or semi-exposed installation.

HO alarms augment main systems, covering areas not reached by the central site alert infrastructure.

The Site-Wide Site Alert Systems

The Howler Site Alert system is suited to smaller and medium-sized sites. Each unit can work independently or be wired together with a maximum of 20 others. When activated, all connected units will sound and flash, ensuring comprehensive coverage.

• Audible warning: Approx. 100 dB at 1 m


• Visual cue: Built-in red LED beacon


• Best used where cable runs are feasible

Site Alert RF

Where wiring is unworkable, the Site Alert RF allows up to 30 devices to connect wirelessly to a master unit. With up check here to 1 km open-air range and multiple frequency channels, this setup is ideal for larger or temporary layouts.

Hybrid arrangements using both wired and wireless units are common and deliver better coverage.

Using the GOLink System Effectively

GOLink acts as a radio-linked backbone, supporting site-wide communication and coordination.

GOLink Interface Unit

This module connects Howler alarms to third-party infrastructure (e.g. CCTV, access control), allowing signals to cascade when an event occurs. Up to 127 stations can communicate over the GOLink network.

First Aid Alert Feature

Some models, such as the H05 GOLink, include separate fire and first aid switches. The latter sends a discreet assistance signal to a control point without triggering full evacuation unless specified.

Best Practices for Deployment

• Zone planning: Divide the site into clear zones (e.g. cabins, workshops) and locate alarms for optimal reach.


• Wired & wireless balance: Use wired alarms where infrastructure allows; RF units in more mobile areas.


• Regular testing: Weekly or monthly inspections to confirm functionality and battery levels.


• Staff training: Ensure all personnel understand alarm tones, first aid indicators, and emergency response steps.

FAQs

Max alarm connections?

Up to 20 wired Site Alert units using 2-core cable.

Wireless range of Site Alert RF?

Approx. 1 km in open air (may reduce with obstacles).

Is a panel required?

No. HO alarms operate independently without central panels.

Integration options?

Yes, via the Interface Unit. External systems such as CCTV and turnstiles can be integrated.

What is an alarmed switch cover?

It reduces false alarms by requiring cover removal before pressing. An alert sounds if tampered with.

Can wired and RF units be used together?

Yes. Mixed networks are common and synchronised through the GOLink system.

First aid switch impact?

No. The signal is isolated unless configured otherwise.

Summary & Next Steps

Effective fire safety requires adaptable, clearly communicated alarm strategies. The Howler range, including HO alarms, Site Alerts and GOLink systems, provides robust protection for sites of all types.
