What if I have a door or window open when I’m setting the alarm?

SimpliSafe will warn you that a door or window is open with a message on the Keypad that says “1 Entry Sensor open” or “Entry Sensors open”, and also with a voice prompt from the burglar alarm's Base Station. Close open doors / windows. If you do not, those doors / windows will not be protected in the event of an emergency. Once you close them, they will then be protected.
