Understanding Howler Systems in Fire Safety
Construction and temporary sites face unique fire risks due to variable layouts, mobile equipment, and dispersed work zones. A reliable alarm network is vital for quickly notifying everyone in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a flexible, adaptable approach suitable for diverse environments.
What are HO Alarms?
HO alarms are self-contained, standalone units designed for mobile spaces such as site cabins or unconnected site areas. No hard-wired connection is required, making installation simple.
- High output: Generally 102 dB at 1 metre.
- Visual indicators: 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 Howler Site Alert Systems
The Howler Site Alert system is suited to smaller and medium-sized sites. Each unit can work independently or be wired together with a maximum of 20 others. When triggered, 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
here
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 larger or temporary layouts.
Hybrid installations using both wired and wireless units are common and deliver better click here coverage.
GOLink Integration
GOLink acts as a radio-linked backbone, supporting site-wide communication and coordination.
System Integration
This module connects here Howler alarms to external systems (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, include separate fire and first aid switches. The latter sends a discreet assistance signal to a control point 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.
- First aid switch impact?
- No. The signal is isolated unless configured otherwise.
