Connect the 1N4004 as close as possible accross the lock power output terminals 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.
Always connect TAMPER terminal to (-) ground if not used.

Description
Auxiliary keypad is for expanding the system to multi-station operation. 4 auxiliary keypad-readers AR-2802, AR-2806
and AR-2807 are compatible with the server keypad in the system. Simply connect the auxiliary keypad-readers in
parallel to the Data I/O bus and maximum 3 are allowed. They provide the same function like the server keypad in
reading cards and user codes. This approach gives high sabotage prevention and user convenience.
