positive PN pressure 

drop value

Voltage of open-circuit is 

about 1.5V 

Interrupted circuit

The resistance of two 

tested points is <(50±5)

Ω, and the buzzer is 

ringing

Cautions: the buzzer is ringing or not if the resistance is between 

50-100Ω, and the buzzer will not ring if it is >100Ω.

Overload Protection: AC250V
