For an insurance-approved alarm system they are here a conditio sine qua
non. They are integrated in a "system clear" line which wouldn't allow you
to arm the panel as long as the line isn't closed. On the other hand this
line type doesn't cause an alarm if opened. So no problem at all with false
alarms. Some examples without knowing what's available at where you live:

GE / Aritech:

Esser / Novar / Honeywell:

Obviously your windows are required to be integrated as well (eg. some push
open mechanism).

Kind regards
