For DC load, the jumpers can be used within the limit of 12V/1A safely.
To connect an AC load, 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 4 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, jumpers should be removed.
Example:
If you connect an AC load to the alarm output 3 of the NVR, then you must remove the JP 3.
