will the alarm go off if i just open and go out the window? or are those just the doors that trigger them?
It really depends on what kind of alarm you have setup and how it's configured...any decent security system will also have sensors on the windows.
Usually, you have everybody leave the house, then set the alarm, then close & lock the door behind you. The alarm system has a "2 minute window" during which the open door won't sound, etc.
Seriously? Like seriously? And it depends on where the sensors are. Usually, most homes will have sensors where people can get in. Also preventing people from getting out...
set it with a time limit, and get out before then
