Configuration: Alarm Input; Configuration: Alarm Output - Swann NVR16-7200 User Manual

English
The Alarm Input menu will allow you to customize and configure
how you'd like the NVR to interpret input from and respond to the
sensor input panel on the rear of the NVR.
Alarm Input No.: The connection that corresponds to the input
you've connected the sensor to. Note that the Alarm Input
Number and the Channel Number don't have to be the same. The
<- characters indicate that these are alarm inputs.
Alarm Name: The name you want to associate with the alarm. We
suggest something descriptive and useful, such as "Lounge Room
PIR Sensor" or "Front Door Sensor". The NVR will use this name in
email alerts and in the event log to let you know where alarms are
being generated.
Type: Whether the sensor is a NO (normally open) or NC (normally
closed). You'll need to check your sensor's documentation to learn
the correct value to use. It refers to the way the sensor tells the
NVR when it has detected something. If this is set to the wrong
value, you'll get constant "false" alarms, which will stop only when
the sensor detects something.
Here you can control the operation of the NVR's Alarm Out
port. Note that the alarm output(s) on the NVR is Normally
Open (NO). If you've got an external device, it must be
configured to use a NO triggering method; otherwise they'll
be in a permanently alarmed state.
Alarm Output No.: The connection that corresponds to the
output you've connected an external device to.

this will constantly trigger alarm events.
