The Safety Monitor setting setting allows you to receive push notifications every time your contact sensor is opened and closed, even when your system is disarmed. You can keep track when your windows or doors are opened, without triggering the alarm.
By default, Safety Monitor is turned on. To turn it off, 
1. Launch the iSmartAlarm app
1. Tap on the three green lines above the Arm mode
2. Tap Notifications
