How shall pre action systems protecting freezers be trip tested?

Explanation:
Pre-action systems keep their piping dry until a release is triggered, so the trip test must be done in a way that avoids introducing moisture into the piping. If moisture gets into the dry pipes, it can lead to false releases, corrosion, or freezing damage in the freezer area, and it compromises the test results. The test should be conducted with proper procedures to prevent any moisture ingress, and afterwards any water introduced should be removed and the system restored to its dry condition.
