CTRL +12V Control power output. Always close the device power to cancel the
alarm.
+12V External power output. Need the peripheral equipment to provide
+12 V power (below 500 mA).
G Ground cable.
Connecting the alarm input
Each (alarm) input line can be switched by a contact from an external device between a
numbered input and ground (G). Wire the inputs as either Normally Open (NO) or Normally
Closed (NC) and configure them as NO or NC in the system menu (Settings > Alarm). The
default is NO.
See the following guidelines:
– Parallel connect the COM end and GND end of the alarm detector (provide external
power to the alarm detector)
– Parallel connect the DVR ground and the alarm detector ground
– Connect the NC port of the alarm sensor to the DVR alarm input (ALARM)
– Use the same ground as the DVR if external power is used for the alarm device
– When connecting two DVRs (or one DVR and one other device), use a relay to separate
them
