DIP Switch Fault
The DIP Switch Fault trouble condition indicates that one or more of a controller's operating mode DIP switches were detected in the ON position upon power-up.
DIP switches left in the ON position are expected to result in network connectivity issues, failed over-the-air (OTA) firmware upgrades, or could introduce other unexpected behaviors.
To resolve a DIP Switch Fault with Mercury series hardware:
Note: By default, the DIP switches on the Mercury series door controllers (i.e., ADC-AC-LP1501, ADC-AC-LP1502, and ADC-ACC1-17) come pre-set in the ON position and need to be adjusted to the OFF position required for normal operation.
- Turn the DIP switches to the OFF position as displayed below.
- Power cycle the controller.

To resolve a DIP Switch Fault with HID series hardware:
Note: By default, the DIP switches on HID series door controllers (i.e., ADC-AC-X1100) come pre-set in the OFF position required for normal operation.
- Turn the DIP switches to the OFF position as displayed below.
- Power cycle the controller.
