The Importance of Howler Systems in Fire Safety

Construction and short-term sites present unique fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is vital for quickly notifying everyone in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a flexible, adaptable solution suitable for varied environments.

Overview of HO Alarms?

HO alarms are battery-operated, standalone units designed for temporary spaces such as site cabins or unconnected site areas. No hard-wired connection is required, making installation simple.

• Loud warning: Typically 102 dB at 1 metre.


• Strobe integration: Available units feature a strobe light alongside the audible siren.


• Durable casing: Many are IP-rated for external or semi-exposed conditions.

HO alarms augment main systems, securing areas not reached by the primary site alert infrastructure.

The Howler Site Alert Systems

The Howler Site Alert system suits smaller and medium-sized sites. Each unit can work alone or be wired together with a maximum of 20 others. When activated, all connected units will sound and flash, ensuring broad 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 impractical, the Site Alert RF allows up to 30 devices to connect wirelessly to a master unit. With up to 1 km open-air range and multiple frequency channels, this setup is ideal for sprawling or temporary layouts.

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

GOLink Integration

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

System Integration

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.

Dual Use Functionality

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

Effective Site Planning Tips

• 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

How many alarms can I link together?

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).

Do HO alarms need a control panel?

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.

Purpose of switch covers?

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

Hybrid system support?

here

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 relies on adaptable, clearly communicated alarm strategies. The Howler suite, including click here HO alarms, Site Alerts and GOLink systems, provides robust protection for sites of all types.
