ALARM INPUT INSTALLATION
The DX8100 has either 8 or 16 dry contact alarm inputs, depending on your system’s configuration. Each input is programmed to function as
either a normally open or normally closed circuit.
To wire an alarm input:
1. Insert the green terminal blocks into the alarm sockets on the back panel of the recorder.
2. Connect one wire from the source device to one of the sensor input terminals 1 through 16.
3. Connect a second wire from the source device to a GND terminal.
4. Refer to the DX8100 Operation/Programming manual for information on how to program the alarm inputs.
