Reinstalling a Door Sensor for an Alarm System

A door sensor for an alarm system ensures that the homeowners know if the door has been opened. This not only protects the house from intruders, it can also inform parents if a child or vulnerable person has opened the door and can prevent the individual from accessing the street unattended. Reinstalling a door sensor after it has been removed involves the same procedure as the original installation. This can be achieved in a few simple steps and doesn't require the assistance of a professional.

Instructions

1. • 1

     Affix the magnet part of the door sensor on the door frame. Position the magnet at a height of around 5 foot 2 inches to avoid it being knocked by children.

   • 2

     Attach the emitter part of the sensor to the door. Ensure that the two halves are exactly parallel to each other.

   • 3

     Keep the distance between two parts of the sensor less than about 1/2-inch apart. The exact distance required will depend on the model of the alarm.
