Understanding Howler Systems in Fire Safety
Construction and short-term sites face distinct fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm setup is vital for promptly alerting all personnel in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a flexible, customisable approach suitable for diverse environments.
Overview of HO Alarms?
HO alarms are self-contained, standalone units intended for temporary spaces such as site cabins or unconnected 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 outdoor or semi-exposed conditions.
HO alarms extend main systems, securing areas not reached by the central site alert infrastructure.
The Howler Site Alert Systems
The Howler Site Alert system suits smaller and medium-sized sites. Each unit can work independently or be wired together with up to 20 others. When activated, every linked alarm 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

Site Alert RF
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 installations using both wired and wireless units are common and deliver better coverage.
GOLink Integration
GOLink acts as a wireless hub, supporting site-wide communication and coordination.
GOLink Interface Unit
This module connects Howler alarms to external systems (e.g. CCTV, access control), allowing click here 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 mobile 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.
FAQs
- Max alarm connections?
- 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.
- 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.
- Does first aid alert trigger full system?
- No. The signal is isolated unless configured otherwise.
