Regarding Buzzer
Pressing the buzzer stop switch stops the buzzer.
When the system detects another water leakage or a break, the buzzer sounds again. Turning No.1 operational
setting switch ON prevents the buzzer from sounding at any time.
It is possible to set the buzzer from the host system by the Modbus communication.
