Alarm mode can be turned on or off
The alarm is triggered by shock vibration or possible sabotage (eg: an attempt to turn off the alarm or an attempt to change the position of the handle when the window is open for vertical ventilation).
When the alarm is activated, the handle also locks, which is a great protection to prevent small children from opening it themselves.
There are other useful features.
The audible alarm goes off by itself after a few minutes.
