ELECTRIC LOCK
• Connect the 1N4004 as close as possible to the lock in parallel with the lock power terminals of the lock to absorb
the back EMF to prevent it from damaging the keypad. The 1N4004 is not required if the electric lock is AC operated.
• To avoid Electro-Static-Discharge from interfering with the operation of the keypad, always ground the (-) terminal
of the keypad to earth.
• Always connect DOOR SENSOR terminal to (-) ground if not used.
