When installing an Aspirating Smoke Detection (ASD) system, it is often almost impossible to identify the exact location of sampling point and more importantly, identify if the sampling hole is the correct size, creating unnecessary delays. The VESDA Sampling Hole Clip delivers reliable and accurate sampling hole sizes that are fast to install and easy to locate and identify. Each clip is colour-coded to indicate a specific hole diameter providing an instant visual guide and removing the need for closer inspection. This is particularly beneficial during commissioning and maintenance processes in applications like warehouses or large open spaces.
