APPLICATION EXAMPLES

1) BASIC WIRINGS OF A STAND ALONE DOOR LOCK

HAA2866

NOTE:

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.
