The Importance of Howler Systems in Fire Safety
Construction and short-term sites present unique fire risks due to ever-changing layouts, mobile equipment, plus dispersed work zones. A dependable alarm network is vital for promptly alerting all personnel in case of danger. The Howler range – including the GOLink system, HO alarms, and site alert units – offers a scalable, adaptable approach suitable for varied environments.
What are HO Alarms?
HO alarms are self-contained, standalone units designed for mobile 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.
- Visual indicators: 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, 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 alone 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 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 get more info setup is ideal for larger or temporary layouts.
Hybrid installations using both wired and wireless units are common and deliver better coverage.
GOLink Integration
GOLink acts as a wireless hub, supporting complete communication and coordination.
System Integration
This module connects Howler alarms to third-party read more infrastructure (e.g. CCTV, access control), allowing signals to 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, include separate fire and first aid switches. The latter sends a non-intrusive 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 locate alarms 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.
FAQs
- 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).
- Is a panel required?
- No. HO alarms operate independently without central panels.
- Integration options?
- 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.
- Hybrid system support?
- 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.
