The alarm input/output interface of the DVR is shown below:
The alarm input is an open/close relay. If the input is not an
open/closed relay, follow the connection diagram below:
To connect to an 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 (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.
Note: An external relay is needed to prevent electric shock
when connecting to an AC load.
