Peripheral Connections
Note:
Alarm input/output connections are valid for the 7300 and 8100 models only.
Connecting to Alarm Input / Output Device
The alarm input is an open/closed 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.
