Alarm In 1 through 16
This DVR is capable of responding to event signals
from external alarm in devices. Connect mechanical
or electrical switches to AI 1 through 16 and the GND
(ground) connector. In order to be recognized by the
DVR, the signal from an alarm in device must be less
than 0.3V (Normally Open) and maintained for at least
0.5 seconds. The alarm in voltage range is 0V to 5V. For
more information on alarm in setup, refer to the
Alarm-
In in the operation manual
.
●
GND (Ground)
Connect alarm in or out's ground cable to the GND
connector.
All connectors marked "GND" are common connectors.
●
NC/NO (Relay Alarm Outputs)
This DVR is capable of activating/deactivating buzzers,
lights, and other external devices. Connect the device
to the 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 in the operation manual
.
●
ARI (Alarm Reset In)
An external signal to the Alarm Reset In can be used to
reset both the Alarm Out signal and the DVR’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.
