Rs-485 And Controller Connection - HIKVISION DS-8104AHQLI-K4 Quick Start Manual

For DC load, the jumpers can be used within the limit of 12V/1A safely.

motherboard in the DVR). 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 DVR, then you must remove the JP3.
