Understanding Howler Systems in Fire Safety

Construction and short-term sites present distinct fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is essential for promptly alerting all personnel in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a flexible, adaptable approach suitable for varied environments.

Overview of HO Alarms?

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

• High output: Typically 102 dB at 1 metre.


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


• Weather resistance: Many are IP-rated for external or semi-exposed conditions.

HO alarms extend main systems, securing areas not reached by the primary 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 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 installations using both wired and wireless units are common and deliver better coverage.

Using the GOLink System Effectively

GOLink acts as a wireless hub, supporting site-wide communication and coordination.

GOLink Interface Unit

This module connects howler ho alarms 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 howler site alarms 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 position units for optimal reach.


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


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


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