After adding the device to the software, the first thing to do is to configure the operating mode of the door sensor.

The purpose is to activate an audible alarm and generate an event in case of abnormal door opening, therefore, the "Door Contact" should be left as "Normally open".
It is advisable to apply times of a few seconds for opening the door.

Create a link to the device and select the "Abnormally open door" option and select door 1.
The "Buzzer on controller" option must be enabled to sound the alarm on the device
.
If there is a possibility to install an anti tamper controller through the RS485 port it would be possible to activate a second alarm output to sound a siren or connect to an alarm center.
