Alarm Output - Q-See QC SERIES User Manual

The accompanying diagram (Picture A-2), along with your alarm's manual should be
consulted to ensure proper connection.
• Normal open or Normal close type
• Parallel connect COM end and GND end of the alarm detector (Provide external power to
the alarm detector).
• Parallel connect the Ground of the combo NVR and the ground of the alarm detector.
• Connect the NC port of the alarm sensor to the combo NVR alarm input(ALARM)
• Use the same ground with that of combo NVR if you use external power to the alarm device.

ALARM OUTPUT

The alarm output port should not be directly connected to a higher power load (greater than
1A) to avoid high current which may damage the relay. Use the co-contactor to establish the
connection between the alarm output port and the load.
• 2 way relay alarm output (NO contact). Provides external power to external alarm device.
• To avoid overloading, please read the following relay parameters sheet carefully.
• RS485 A/B cable is for the A/B cable of the PTZ camera.
