Entrance Keypad Diagnostics
To test the keypad, there is a diagnostic mode you can put it in to verify its
functionality. Remove the four screws and remove the top of the keypad. Flip
it over, you will see the DIP switch settings. Turn DIP switch 4 on, and press
the reset
button to the immediate left of the DIP switches. Now, the number
LED’s will be flashing. If you press a number once, it will go solid, if you press
it again, it will shut off, if you press it again, it will flash again. Do this
for each
one of the numbers. The roller button will be off, if you press it once, it will
turn on, if you press it again, it will turn off. If you press the AC button, it will
toggle all of the number keys. If you press the $
sign or the up arrow, the
printer will print, “this is a test…,” every time you press either button. If any of
these keys do not respond correctly, contact your distributor for a
replacement keypad.
