Fire Safety on Building Sites
Building environments, especially those in a transitional phase, introduce specific fire hazards due to shifting layouts, mobile equipment, and scattered 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 setup to match various site demands.
What Exactly Are HO Alarms?
HO alarms are self-powered, battery-operated units used where traditional systems are impractical. Ideal for portable 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 provide supplementary coverage where the main alert network may not reach.
The Howler Site Alert Range
Suitable for mid-sized projects, the Site Alert system can work as standalone or in groups 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 open-area range of around 1 km and supports multiple frequencies for interference avoidance.
Combining wireless and cabled systems is frequently the best choice for sites with varying structures.
Integrating the GOLink System
The GOLink system acts as a communication core for large, multi-zone installations, click here using wireless signals to link alarms.
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 here first aid button alongside the fire alert. The first aid signal quietly sends howler golink systems a location-specific assistance request, allowing medical needs to be flagged without general evacuation.
Deployment Guidelines
- Zone assessment: Identify where alarms need to be heard or seen, 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 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.
- Do HO alarms need a base station?
- 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.
- Why use an alarmed switch cover?
- 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.
- Will first aid alerts trigger full alarms?
- No. It sends a targeted alert to designated receivers without activating evacuation systems—unless configured otherwise.
