Testing of Sprinkler and Deluge Systems

Wet and dry pipe sprinklers are not functionally tests for coverage since design codes have eliminated problems with distribution patterns, provided the installation has been adequately inspected. The normal testing verifies adequate pressure is available, piping is not plugged and activation of alarms occurs. 

A full functional wet test of the deluge system is normally accomplished. This test ensures coverage and density patterns are being achieved. A calculated collection pan can be provided during the testing to confirm the density rate per minute. The mechanism to activate the deluge should be tested under conditions that will simulate as real as can be reasonably obtained. Where equipment to be protected is not normally in place, i.e., ships, trucks or rail cars, the test should not be conducted until they are in their normal position during operations.
