The Importance of Howler Systems in Fire Safety
Construction and temporary sites present distinct fire risks due to ever-changing 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 scalable, customisable solution suitable for diverse environments.
Overview of HO Alarms?
HO alarms are battery-operated, standalone units designed for mobile spaces such as site cabins or remote site areas. No hard-wired connection is required, making installation straightforward.
- High output: 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 augment main systems, covering 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 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 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 offer better coverage.
GOLink Integration
GOLink acts as a radio-linked backbone, supporting complete communication and coordination.

System Integration
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 howler ho alarms communicate over the GOLink network.
First Aid Alert Feature
Some models, such as the H05 GOLink, include separate fire and first aid switches. The latter sends a non-intrusive 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: Ensure 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.
- 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.
- 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.
- First aid switch impact?
- No. The signal is isolated unless configured otherwise.
