How to Reset an ADT Home Alarm

ADT home alarm systems are equipped with sensors that electronically alert the alarm keypad when security zones are breached. Some types of ADT alarm system sensors must be manually reset when they detect a security event, such as a broken window. You do not need to contact ADT to reset these sensors. As long as the event that triggered the sensor to sound your alarm has been resolved, you can follow these steps to reset your ADT home alarm.
