Ensuring Construction Site Safety with Howler GOLink, HO and Alert Systems


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 essential for quickly notifying everyone in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a flexible, customisable solution suitable for varied environments.





Overview of HO Alarms?



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



  • Loud warning: Generally 102 dB at 1 metre.

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

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



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





The Howler 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 triggered, 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 straightforward



Wireless Variant



Where wiring is unworkable, 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 website coverage.





Using the GOLink System Effectively



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



System Integration



This module connects Howler alarms to external systems (e.g. CCTV, here 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 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 temporary areas.

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

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