Understanding Howler Systems in Fire Safety

Construction and temporary sites present distinct fire risks due to variable layouts, mobile equipment, and dispersed work zones. A dependable alarm network is vital for quickly notifying all personnel in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a scalable, adaptable solution suitable for diverse environments.

What are HO Alarms?

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

• Loud warning: Generally 102 dB at 1 metre.


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


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

HO alarms extend main systems, securing areas not reached by the central site alert infrastructure.

The Site-Wide Site Alert Systems

The Howler Site Alert system is suited to compact and medium-sized sites. Each unit can work independently or be wired together with up to 20 others. When triggered, 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

Wireless Variant

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 installations using check here both wired and wireless units are common and deliver better coverage.

Using the GOLink System Effectively

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

System Integration

This module connects Howler alarms to external systems (e.g. CCTV, access control), allowing get more info 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 H05 GOLink, incorporate 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: Map 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 temporary 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.

How far does it reach?

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

Is a panel required?

No. HO alarms operate independently without central panels.

Can GOLink connect to other systems?

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.

Final Thoughts

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