Wiring of alarm input
The alarm input is an open/closed relay. To connect the alarm input to the
device, use the following diagram.
Note:
If the alarm input is not an open/close relay, connect an external relay
between the alarm input and the device.
Wiring of alarm output
Note:
Connect to a security system zone.
To connect to an alarm output (AC or DC load), use the following diagram.

AC Load Connection Diagram
For DC load, the jumpers can be used within the limit of 12 V/1A safely.
To connect an AC load, the jumpers should be left open (you must remove the
jumper on the motherboard in the NVR). Use an external relay for safety (as
shown in the figure above).
There are four jumpers (JP1, JP2, JP3, and JP4) on the motherboard, each
corresponding with one alarm output. By default, jumpers are connected. To
connect an AC load, the jumpers should be removed.
Example:
If you connect an AC load to the alarm output 3 of the NVR, then you must
remove the JP3 jumper.
