Well I hope yours does work, felix. One of my neighbours has an indoor alarm system also installed by a reputable company. Damn thing goes off all the time. Day, night, you name it. Nobody pays any attention to it so it's pretty pointless turning the stupid thing on.
SOG, I had a similar situation.... lived in a VERY low crime area, neighbors house was used as a holiday house, they were there every second weekend or so. Their alarm would go off all the time, the first half dozen times I checked on his house to make sure all was ok.
After being woken up heaps of times by false alarms I politely asked my neighbour if he could do something to reduce the alarms. He refuses. Apparently it was not his problem.

I ask him for his phone number so I can call him when it goes off and he can reset it by phone. He refuses.

In the end, each time it false alarmed, persons unnamed would turn his power off at the meter (yes, batteries do keep the alarm going, but not forever).
As for the freezer full of rotten food that awaited his eventual return.....
Apparently that is not my problem
