The Importance of Howler Systems in Fire Safety
Construction and temporary sites present unique fire risks due to variable layouts, mobile equipment, and 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 varied environments.
Overview of HO Alarms?
HO alarms are self-contained, standalone units designed for temporary spaces such as site cabins or remote site areas. No hard-wired connection is required, making installation simple.
- High output: Typically 102 dB at 1 metre.
- Visual indicators: Optional units feature a strobe light alongside the audible siren.
- Weather resistance: Many are IP-rated for external or semi-exposed installation.
HO alarms augment main systems, covering areas not reached by the primary site alert infrastructure.
The Howler Site Alert Systems
The Howler Site Alert system is suited to compact and medium-sized sites. Each unit can work alone or be wired together with a maximum of 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
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 here and multiple frequency channels, this setup is ideal for larger or temporary layouts.
Hybrid arrangements using both wired and wireless units are common and offer better coverage.
GOLink Integration
GOLink acts as a wireless hub, 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 communicate over the GOLink network.
First Aid Alert Feature
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 position units 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
- 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.
- Can GOLink connect to other systems?
- Yes, via the Interface Unit. External systems such as CCTV and turnstiles can be integrated.
- Purpose of switch covers?
- 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.
