Peripheral Connections

This section is applicable for the DS-8600NI-E8, DS-7700NI-E4 and DS-7700NI-E4/P series only.

Wiring of Alarm Input

The alarm input is an open/closed relay. To connect the alarm input to the device, use the following diagram.
If the alarm input is not an open/close relay, please connect an external relay between the alarm input and the
device.

Wiring of Alarm Output

To connect to an alarm output (AC or DC load), use the following diagram:
DC Load Connection Diagram AC Load Connection Diagram
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.

Using of Alarm Connectors

To connect alarm devices to the NVR:
1. Disconnect pluggable block from the ALARM IN /ALARM OUT terminal block.
