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. The greatly simplified installation process helps deliver greater reliability in the correct setting of sampling hole size and a faster installation process. A 10mm (27/64") diameter drill bit is all that is required by an installer to create each sampling hole (rather than many different drill sizes) to which the Sampling Hole Clip attaches to. This can help deliver quality installation in projects where installation is sub contracted or the installer is not familiar with the impact of sampling hole size. Use of a chamfered hole entry in the sampling hole clip design can help to reduce dust loading effects. Without using this type of technology, a build-up of dust around a standard drilled sampling hole is likely to occur, due to the friction created by the airflow through the sampling hole. By reducing dust loading effects and leveraging the additional protection provided by the pipe clips, sites can help increase system uptime and potentially extend service and testing intervals.
