CONNECTING ALARMS
The DX4500/DX4600 provides a numbered terminal block for connecting alarm devices. Alarms are programmed for normally open or normally
closed inputs. Eight-channel DVRs support up to 8 alarm devices; 16-channel DVRs support up to 16 alarm devices. For information about
configuring the alarm inputs, refer to the DX4500/DX4600 Operation/Configuration manual.

3. Push in one of the alarm ground terminal block retainers.
