Managing Fire Hazards on Site
Building environments, especially those in a transitional phase, present specific fire hazards due to shifting layouts, relocatable equipment, and scattered workforces. A sound alerting system is necessary for ensuring all personnel are aware without delay. The Howler range, including the GOLink system, HO units, and site alert models, provides a scalable safety setup to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated units used where traditional systems are not viable. Ideal for moveable cabins or outbuildings, they require no wiring.
- Loud alarm: Around 102 dB at a metre’s distance.
- Visual signal option: Some models include integrated lights for visibility.
- IP-rated: Many are suited for outdoor use or partially exposed areas.
These alarms offer additional coverage where the core alert network may not reach.
The Site-Wide Alert Range
Suitable for compact projects, the Site Alert system can work as standalone or in linked setups of up to 20 units using a simple two-core cable. When triggered, all devices in the series respond simultaneously.
- Approx. 100 dB sound level at 1 metre
- Built-in flashing beacon for loud or noisy settings
- Recommended where cabling is straightforward
Going Wireless: Site Alert RF
Where cabling is limited, Site Alert RF links up to 30 units over wireless. It get more info has an line-of-sight range of around 1 km and supports multiple channels for interference avoidance.
Combining wireless and cabled systems is frequently the best strategy for sites with varying structures.
Integrating the GOLink System
The GOLink system serves as a communication core for large, multi-zone installations, using wireless signals to connect multiple devices.
GOLink Interface Connections
Through the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety components. Up to 127 points can interact across a site-wide network.
Dual-Function Features
Certain models (e.g. H05 GOLink) include a first aid button alongside the fire alert. The first aid function quietly sends a location-specific assistance request, allowing medical needs to be flagged without general evacuation.
How to Deploy Effectively
- Zone assessment: Identify where alarms need to be noticeable, dividing the site into manageable sectors.
- Choose connection types wisely: Use hard-wired alarms where feasible, supplementing with RF in distant or pop-up areas.
- Set a maintenance routine: Schedule regular testing and check battery levels.
- Training & signage: Ensure directions are posted and team members know how to respond to alerts.
Common Questions
- Wired capacity?
- Up to 20 Site Alert units can be connected using 2-core cable.
- What’s the wireless range of Site Alert RF?
- Approx. 1 km in open-air conditions, though physical obstructions can reduce range.
- HO panel required?
- No, HO models are standalone and do not require central control.
- Can GOLink interface with other site systems?
- Yes, external systems can be connected via the GOLink Interface Unit.
- Why use an alarmed switch cover?
- It reduces false alarms by sounding a warning if tampered with before activation.
- Hybrid setup compatibility?
- Yes, the GOLink system allows wired and wireless units to operate on the same network.
- Does first aid signal cause evacuation?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
Final Notes
Whether your project involves one zone or several, Howler alarms—HO, GOLink, and Site Alert—deliver protection that adapt to varying conditions. For details, planning here tools or live demos, refer to the Howler section on FireSense.
