4.7 Alarm Terminal Block
The alarm terminal block is located on the cover plate of the device for alarm output.
When the device works normally, the alarm relay normally-open contact is on, and normally-
close contact is off; When an alarm occurs, normally-open contact is off and normally-close
contact is on. The normally-open and normally-close contact of delay is output through the 3-
pin 5.08-spacing plug-in terminal blocks.

Electrical parameters of relay:
Maximum voltage: 250VAC/220VDC
Maximum current: 2A
Maximum power: 60W
Maximum insulation withstand voltage: 2KV
Note:

Pin 1 and Pin 2 is a normally-open contact, Pin 2 and Pin 3 is a normally-close contact. When
the device works normally, it is close between Pin 1 and Pin 2, it is open between Pin 2 and
Pin 3; when an alarm occurs, it is open between Pin 1 and Pin 2, it is close between Pin 2 and
Pin 3.
