CU2200 - activate by powering

Dear Velleman-friends, I have since several years an alarm type CU2200. Recently I notice that I can’t activate the alarm anymore just by input the electric power. The only way to activate the alarm is by sending an SMS.
Is there any possibility to activate also the alarm by setting the power on (and deactivate by switching the power off)? How do I have to programm the unit therefore?
The software-version is SD41 v.7.2 (n).

Thanks a lot for your feedback.
