Explanation differential loops:
Differential loops means that you can connect NC or NO contacts here.
NC = normally closed = opener = the switching contact opens in the case of an alarm
NO = normally open = closer = the switching contact closes in the case of an alarm
Example of the connection of an NC contact sensor and an NO contact sensor:
Ensure that the connection resistance of 2.2 kOhm is connected not to the alarm control centre
but as close as possible to the sensor end.

are attached. You can connect several sensors with NC contacts to
each alarm loop.
