2.3 Connections
Alarm Input Wiring
2.3.1
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.
Alarm Output Wiring
2.3.2
To connect to an alarm output (AC or DC load), use the following 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 (JP6, JP9, JP10, and JP11) 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 jumper.
