Understanding Howler Systems in Fire Safety
Construction and temporary sites face distinct fire risks due to ever-changing layouts, mobile equipment, plus dispersed work zones. A reliable alarm network is vital for promptly alerting everyone in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a flexible, customisable solution 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: Available 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, covering areas not reached by the primary site alert infrastructure.
The Site-Wide Site Alert Systems
The Howler Site Alert system is suited to smaller and medium-sized sites. Each unit can work alone 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 feasible
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 read more frequency channels, this setup is ideal for sprawling or temporary layouts.
Hybrid arrangements 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.
System Integration
This module connects Howler alarms to external systems (e.g. CCTV, access control), allowing signals to cascade when an read more event occurs. Up to 127 stations can communicate over the GOLink network.
Dual Use Functionality

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: Ensure all personnel understand alarm tones, first aid indicators, and emergency response steps.
Frequently Asked Questions
- 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).
- 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.
- Can wired and RF units be used together?
- Yes. Mixed networks are common and synchronised through the GOLink system.
- First aid switch impact?
- No. The signal is isolated unless configured otherwise.
