To connect to an alarm output (AC or 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, the jumpers are connected. To connect an AC load, the jumpers should be removed.
NOTE: An external relay is needed to prevent electric shock when connecting to an AC load.
Using the Alarm Connectors:
To connect the alarm devices to the NVR/DVR:
1. Disconnect the pluggable block from the ALARM IN /ALARM OUT terminal block.
2. Unfasten the stop screws from the pluggable block, insert the signal cables into the slots and fasten the stop
screws. Ensure that the signal cables are in tightly.
3. Connect the pluggable block back to the terminal block.
