Understanding Howler Systems in Fire Safety
Construction and temporary sites face unique fire risks due to variable layouts, mobile equipment, plus dispersed work zones. A dependable alarm setup is vital for quickly notifying 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 battery-operated, standalone units intended 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.
- Strobe integration: Available units feature a strobe light alongside the audible siren.
- Weather resistance: 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 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 straightforward
Wireless Variant
Where wiring is unworkable, the Site Alert RF allows up to 30 devices to connect wirelessly to a master unit. With up to website 1 km open-air range and multiple frequency channels, this setup is ideal for sprawling get more info 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.
System Integration
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.
Dual Use Functionality
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 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 checks to confirm functionality and battery levels.
- Staff training: Make sure all personnel understand alarm tones, first aid indicators, and emergency response steps.
FAQs
- Max alarm connections?
- 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.
- 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.
- Hybrid system support?
- Yes. Mixed networks are common and synchronised through the GOLink system.
- Does first aid alert trigger full system?
