Do not restore the DIP switch addresses to their
original settings.
Disconnect the D9210B that shows "F" in the keypad
display and set it aside. Disconnect the known good
D9210B from its current location, and reconnect it
where the affected D9210B was connected. Refer to
Figure 14 on page 21.
Does the keypad still display "F" for the affected
access door number?
Replace the D9210B that was originally
connected to the affected access door.
Refer to TTP47 Open Wiring
Refer to TTP48 Noise on Wire
