• G (Ground)
Connect alarm in or out's ground cable to the G
connector.
All connectors marked "G" are common connectors.
• NC/NO (Relay Alarm Outputs)
This NVR is capable of activating/deactivating buzzers,
lights, and other external devices. Connect the device to
the C (Common) and NC (Normally Closed) or C and NO
(Normally Open) connectors. NC/NO is a relay output
which sinks 2A@125VAC and 1A@30VDC. For more
information on alarm out setup, refer to the Alarm-Out
on page 62.
• ARI (Alarm Reset In)
An external signal to the Alarm Reset In can be used to
reset both the Alarm Out signal and the NVR’s internal
buzzer. Mechanical or electrical switches can be wired to
the ARI (Alarm Reset In) and GND (Ground) connectors.
The threshold voltage is below 0.3V and should be
stable at least 0.5 seconds to be detected. Connect the
wires to the ARI and GND connectors.
