Alarm Input and Output Connection
Please refer to the following sheet for alarm input and output connection.
There are two alarm input types for you to select: normal open (NO) and normal close (NC).
1. Alarm input
a. Please make sure alarm input mode is grounding alarm input.
b. Grounding signal is needed for alarm input.
c. Alarm input needs the low level voltage signal.
d. Alarm input mode can be either NC (normal Open) or NO (Normal Close)
e. When you are connecting two NVRs or you are connecting one NVR and one other device,
please use a relay to separate them,
2. Alarm output
The alarm output port should not be connected to high power load directly (It shall be less than
1A) to avoid high current which may result in relay damage. Please use the co contactor to
realize the connection between the alarm output port and the load.
3. Please make sure the front-end device has soundly earthed.
Improper grounding may result in chip damage.
