Managing Fire Hazards on Site
Building environments, especially those in a transitional phase, introduce distinct fire hazards due to shifting layouts, mobile equipment, and scattered workforces. A reliable alerting system is crucial for notifying workers without delay. The Howler range, including the radio-based GOLink system, HO units, and site alert models, provides a scalable safety solution to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated devices used where traditional systems are not viable. Ideal for portable cabins or outbuildings, they require no wiring.
- Loud alarm: Around 102 dB at a metre’s distance.
- Optional strobe: Some models include integrated lights for visibility.
- IP-rated: Many are suited for external mounting or partially exposed areas.
These alarms offer supplementary coverage where the core alert network may not reach.
The Site-Wide Alert Range
Suitable for compact projects, the Site Alert system operates individually or in groups 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 visual LED 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 has an open-area range of around 1 km and supports multiple frequencies for interference avoidance.
Combining wireless and cabled systems get more info is commonly the best choice 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.
Connecting to Site Systems
Through the Interface Unit, it’s possible to link turnstiles, autodiallers, read more CCTV, and other site safety components. Up to 127 points can interact across website 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 notifies the control team, 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 weekly testing and monitor battery levels.
- Training & signage: Ensure instructions 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.
- How far does the wireless version reach?
- 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.
- Is third-party integration supported?
- Yes, external systems can be connected via the GOLink Interface Unit.
- Purpose of switch protection?
- It reduces false alarms by sounding a warning if tampered with before activation.
- Can both cabled and RF alarms work together?
- 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 tools or live demos, refer to the Howler section on FireSense.
