Installation Steps:

1. Mount the sensor on the door frame and the magnet on the door. If the sensor is used on double doors mount the sensor on the least frequently used door and the magnet on the most frequently used door.

2. If possible, locate sensors within 100 ft. (30 m) of the panel. While a transmitter may have a range of 350 ft. (106 m) or more out in the open, the environment can have a significant effect on the range.

3. Line up the arrow on the magnet to the alignment mark on the sensor and mount no more than 1/4" apart from each other.
