Before Connecting Alarm Inputs and Outputs

•
Ensure that the alarm input mode is set to ground.
•
Ensure that the signal is grounded.
•
Know that the alarm inputs require low-level voltage signals.
•
Ensure that the alarm input mode is set to either NC (normally closed) or NO (normally
open).
•
Use a relay if you are connecting two NVRs, or a NVR plus another device, to separate
them.
•
Do NOT directly connect the alarm output port to a high-power load. The load should be
less than 1 A to avoid damage.
•
Use the contactor to make the connection between the alarm output port and the load.
