Managing Fire Hazards on Site
Building environments, especially those in a transitional phase, introduce specific fire hazards due to frequent layout changes, relocatable equipment, and divided workforces. A reliable alerting system is necessary for notifying workers without delay. The Howler line-up, including the GOLink system, HO units, and site alert models, provides a tailored safety solution to match various site demands.
What Exactly Are HO Alarms?
HO alarms are independent, battery-operated devices used where hard-wired installations are not viable. Ideal for moveable cabins or outbuildings, they function autonomously.
- 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 external mounting or partially exposed areas.
These alarms offer supplementary coverage where the main alert network may not reach.
The Site-Wide Alert Range
Suitable for mid-sized projects, the Site Alert system operates individually or in linked setups of up to 20 units using a simple two-core cable. When set off, all devices in the network respond simultaneously.
- Approx. 100 dB sound level at 1 metre
- Built-in visual LED for loud or noisy settings
- Ideal where cabling is straightforward
Site Alert RF (Radio-Frequency)
Where cabling is limited, Site Alert RF links up to 30 units over wireless. It has an line-of-sight range of around 1 km and supports multiple channels for interference avoidance.
Blending wireless and cabled read more systems is commonly 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 link alarms.
Connecting to Site Systems
Through the Interface Unit, it’s possible to tie into turnstiles, autodiallers, CCTV, and other site safety website components. Up to 127 points can connect across a site-wide network.
First Aid Callouts
Certain models (e.g. H05 GOLink) include a first aid button alongside the fire alert. The first aid signal 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 temporary areas.
- Set a maintenance routine: Schedule regular testing and check battery levels.
- Training & signage: Ensure instructions are posted and team members know how to respond to alerts.
FAQs
- 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.
- Do HO alarms need a base station?
- 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.
- Purpose of switch protection?
- 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
