The Importance of Howler Systems in Fire Safety
Construction and short-term sites present distinct fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is vital for promptly alerting everyone in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a flexible, customisable solution suitable for diverse environments.
What are HO Alarms?
HO alarms are self-contained, standalone units intended for mobile spaces such as site cabins or remote site areas. No hard-wired connection is required, making installation simple.
- High output: 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 extend main systems, covering areas not reached by the central site alert infrastructure.
The Site-Wide Site Alert Systems
The Howler Site Alert system suits smaller 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 feasible
Wireless Variant
Where wiring is impractical, the Site Alert RF allows up to 30 devices to connect wirelessly to check here 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 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.
GOLink Interface Unit
This module connects Howler alarms to external systems (e.g. CCTV, access control), allowing signals to read more cascade when an event occurs. Up to 127 stations can communicate over the GOLink network.
Dual Use Functionality
Some models, such as the H05 GOLink, incorporate separate fire and first aid switches. The latter read more 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: Make sure 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.
- 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.
- 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.
- Can wired and RF units be used together?
- 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.
Summary & Next Steps
Effective fire safety relies on adaptable, clearly communicated alarm strategies. The Howler suite, including HO alarms, Site Alerts and GOLink systems, provides robust protection for sites of all types.
