Basic wiring of a stand-alone door lock
NOTE:
·
Connect 1N4004 as close as possible to the lock parallel with
the lock power terminals to absorb the back EMF and prevent
keypad damage. The 1N4004 is not required for AC power.
·
To avoid electrostatic discharge from interfering with the
keypad, always ground the terminal.
·
Always connect DOOR SENS to ground.
