The Importance of Howler Systems in Fire Safety
Construction and temporary sites present distinct fire risks due to variable layouts, mobile equipment, and dispersed work zones. A reliable alarm setup is essential for quickly notifying everyone in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a flexible, adaptable solution suitable for varied environments.
Overview of HO Alarms?
HO alarms are battery-operated, standalone units designed for temporary 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: Optional units feature a strobe light alongside the audible siren.
- Durable casing: Many are IP-rated for external or semi-exposed conditions.
HO alarms augment main systems, securing areas not reached by the primary site alert infrastructure.
The Site-Wide Site Alert Systems
The Howler Site Alert system suits 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 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 and multiple 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.
GOLink Integration
GOLink acts as a radio-linked backbone, supporting site-wide 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, 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: 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: Make sure 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).
- 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.
- Purpose of switch covers?
- 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.
