Can the wired portion of a 679 DPS be used along with the magnet portion of a 7764?

It is not recommended as the magnet and switch are sold together since they are tested together. 
The different shape and positioning of the 7764 magnet may not allow the 679 DPS to work properly 
with respect to the gap and distance at which the switch will change state and report the door open or closed.
