Quick Operation Guide of DS-9600/8600/7700/7600NI-ST and DS-7700/7600NI-SP Series NVR
For DC load, JP4 can be used within the limit of 12V/1A safely. If the interface is connected to an AC load, JP4
should be left open. Use an external relay for safety (as shown in the figure above).
There are 4 jumpers (JP4, JP5, JP6, and JP7) on the motherboard, each corresponding with one alarm output. By
default, jumpers are connected. To connect an AC load, jumpers should be removed.
An external relay is needed to prevent electric shock when connecting to an AC load.
