Which device is used to test alarms without discharging the system during testing?

• A. A device used to simulate a waterflow condition during testing so alarms are tested without discharging the system.
• B. A valve that drains the entire system.
• C. A sensor that measures ambient temperature.
• D. A device that increases water pressure during testing.

Answer: (A)

Testing alarms without discharging the system relies on a device that can mimic water movement in the piping. This flow-simulating device lets the waterflow switches and alarm circuits react as if water were actually moving, but without opening a drain or releasing system water. By creating a controlled, temporary flow, you can verify that the audible/visual alarms and central signaling activate properly while keeping the system pressurized and intact. This is exactly what a flow simulant or alarm test device does: it triggers the alarm during testing without discharging the system. The other options would either drain the system, test a different parameter, or fail to trigger the alarm, so they’re not suitable for this purpose.
