The Importance of Howler Systems in Fire Safety
Construction and short-term sites present distinct fire risks due to ever-changing layouts, mobile equipment, plus dispersed work zones. A reliable alarm setup 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 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.
- Weather resistance: Many are IP-rated for outdoor or semi-exposed installation.
HO alarms extend main systems, covering areas not reached by the central site alert infrastructure.
The Site-Wide Site Alert Systems
The Howler Site Alert system suits compact and medium-sized sites. Each unit can work alone or be wired together with up to 20 others. When activated, every linked alarm 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 straightforward
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 more info 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 complete 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.
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 check here 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: Make sure 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.
- 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.
- Hybrid system support?
- Yes. Mixed networks are common and synchronised through the GOLink system.
