Why Does ADT Doorbell Chime?

When you want to hear a specific sound when someone presses your doorbell, opens a door, walks in front of your motion detector, from when there is motion in front of one of your cameras, or when your alarm is going off, you can use the ADT Pulse Chime. This can be used for situations in which you want to be notified of these events. Please notify you whenever a door or window is opened by another person.
