For many S4A devices, the factory default master code is 123456. It is highly recommended to change this code immediately after installation for security purposes.
Generally, you can reset the keypad by removing the rear cover and holding the reset button for about 3 seconds until it beeps. Refer to your specific model's manual for precise steps.
Most S4A standalone controllers and keypads require a 12V DC power supply. Verify the voltage specifications on your device label before connecting power.
When using a common power supply for the access controller and the lock, a 1N4004 diode (often included) should be installed across the lock terminals to protect the keypad/controller from back EMF damage.
