Keypad or key switch does not operate the door, though remotes and wall button work.

Safety: Disconnect power before changing wiring; keypad battery changes can be done with power on.

• Check keypad power: Replace the keypad battery or verify its low-voltage supply if wired.
• Verify wiring: Ensure the keypad or key switch is connected to the correct FAAC terminals (e.g., step-by-step input) and polarity if required.
• Test device directly: Momentarily short the keypad/key switch wires at the device. If the door operates, the device is faulty and should be replaced.
• Reprogram keypad: Follow FAAC or keypad manufacturer instructions to set the correct PIN and link it to the opener.

Label accessory wires clearly to avoid confusion with safety circuits.
