The relay output can connect the device up to 250VAC/10A, and the solenoid valve output is a
12V/100ms pulse output. When the alarm is triggered, the relay output will open the fan and
solenoid valve output will send a pulse to close the valve; when the alarm is dismissed, the relay
output will close the fan, and the valve status will not change. You can open the solenoid valve
manually or via send downlink commands.
