The testing of the alarm system doesn’t necessarily entail the flowing of water and turning of valves; Although it should.

The test is best performed in tandem with the sprinkler company, and some AHJs and jurisdictions require just that. But when the sprinkler contractor isn’t available, the tech can still test the function of the alarm system.

One method I use often is to open the waterflow or tamper switch (where our wires are connected) and manually trip the switch by pushing the lever with your finger. Or, if you aren’t sure about touching their stuff, the other method is to create a short circuit condition across the End Of Line Resistor that should be present at the sprinkler switch device. Both methods will accurately test the fire alarm system’s connection to, and monitoring of, the sprinkler devices all the way to the very end of our scope of responsibility. It doesn’t ensure or test the functionality of the sprinkler system components, but that’s their job and they do it on a regular basis as well. Just make a note on your inspection form the method of testing.
