A.1 CONNECTING ALARMS
Setting up alarm notifications is covered in Section 4.2 in this manual. This section covers how
to connect alarms to your NVR.
IfyourNVRfeaturesconnectionsforexternalalarms–bothinputandoutput,thenitcannotify
local users or send notification to a monitoring service when an event is detected. At the same
time, the system can accept signals from motion detectors, smoke detectors or other alarms
and begin recording based on that input and your settings.
You will need to have the manual for your alarm(s) handy to ensure the proper settings within
the NVR.
ALARM INPUT
When attaching alarms, the following criteria
must be met:
1. The alarm input must be grounded.
2. A grounding signal is required for the
alarm input
3. When connecting the NVR to another
device - including another NVR - through
the alarm input, a relay should be used to
separate them.
