Description

The VESDA Harsh Environment Sampling Hole Clip is designed to enhance the installation and maintenance of Aspirating Smoke Detection (ASD) systems by addressing challenges related to sampling point identification and hole size accuracy. This pre-engineered clip streamlines the commissioning process, ensuring reliable and precise sampling hole diameters that are quick to install and easy to locate.

Each clip is colour-coded to indicate a specific hole diameter, providing an immediate visual reference crucial for large-scale applications such as warehouses. The installation process is simplified, requiring only a single 10mm drill bit for all sampling holes, into which the clip securely clicks into place. This standardisation improves installation quality, particularly when carried out by sub-contractors or less familiar installers.

A key feature of the harsh environment variants is the flexi-lip design, which adapts under compressed air to dislodge ice, fibres, or dust buildup, preventing contamination of the sampling hole. Furthermore, a chamfered hole entry design actively reduces dust loading effects, enhancing system uptime and potentially extending service and testing intervals by mitigating friction-induced particle accumulation.

Unlike many alternatives, the pipe clip is supplied as a single, ready-to-fit component, requiring no additional assembly, parts, or tools. Its robust design contributes to greater reliability in maintaining the correct sampling hole size and accelerating the overall installation procedure.

Eurofyre, an authorised distributor for Honeywell, supplies these clips, which are suitable for a maximum pipe network pressure of 7 bar and an application temperature range of -30°C to +45°C.
