To install model 2507AH, do the following:
1. Mount switch in desired location.
2. Attach an ohmmeter to the black and white wires. The
meter should read infinity with the magnet away from the
switch.
3. Bring the magnet toward the switch until the meter reads
zero ohms. Mark this position.
4. Bring the magnet closer to the switch until the meter reads
infinity. Mark this position.
5. Position the magnet between the two marks.
6. Align the magnet and switch so the labels read in the same
direction. With the magnet positioned in this manner, the
switch will be harder to defeat with an external magnet.
