To connect to an alarm output (AC/DC load), use the following diagram:
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 (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.
Note:
An external relay is needed to prevent electric shock when connecting to an AC load.
Using of Alarm Connectors
To connect alarm devices to the NVR:
1.
Disconnect
pluggable block
from the ALARM IN /ALARM OUT terminal block.
2.
Unfasten stop screws from the
pluggable block
, insert signal cables into slots and fasten stop screws. Ensure
signal cables are in tight.
3.
