The Importance of Howler Systems in Fire Safety
Construction and temporary sites present unique fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A reliable alarm network is essential for promptly alerting everyone in case of danger. The Howler range – including GOLink, HO alarms, and site alert units – offers a scalable, adaptable solution suitable for diverse environments.
What are HO Alarms?
HO alarms are battery-operated, standalone units designed for mobile spaces such as portable offices or unconnected site areas. No hard-wired connection is required, making installation straightforward.
- Loud warning: Generally 102 dB at 1 metre.
- Strobe integration: Available units feature a strobe light alongside the audible siren.
- Durable casing: 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 Site-Wide 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 up to 20 others. When triggered, all connected units 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
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 arrangements using both wired and wireless units are common and offer better coverage.
GOLink Integration
GOLink acts as a wireless hub, supporting complete communication get more info 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: Divide 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 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
- 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.
