Understanding Howler Systems in Fire Safety
Construction and temporary sites present unique fire risks due to ever-changing layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is vital for quickly notifying everyone in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a scalable, customisable solution suitable for diverse environments.
Overview of HO Alarms?
HO alarms are battery-operated, standalone units intended for temporary spaces such as portable offices or unconnected site areas. No hard-wired connection is required, making installation simple.
- Loud warning: Typically 102 dB at 1 metre.
- Strobe integration: 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 primary 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 triggered, 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
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 larger or temporary layouts.
Hybrid installations using both wired and wireless units are common and offer 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 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 non-intrusive assistance signal to a control point read more 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 inspections 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.
- 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.
- 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.
