In a sprinkler system, the clapper valve is found in the:

The clapper valve is part of the alarm check valve. This device combines a check valve with an alarm mechanism, and inside it a clapper sits on a seat. When water begins to flow through a sprinkler head, the pressure moves the clapper, opening the valve to allow flow into the system and simultaneously triggering the alarm switch. The clapper also helps prevent backflow when there’s no flow. The other components—alarm test valve, retard chamber, and alarm shutoff valve—do not contain a clapper and serve different purposes (testing, dampening, or isolating the alarm), so they aren’t the correct location for the clapper valve.
