Wiring a Door Operator to the UniFi Access Control Hub

This article provides wiring instructions for connecting door operators to UniFi Access Control Hubs, enabling automated door operation for improved accessibility and safety. If you've already wired your terminals and are looking for configuration instructions within UniFi Access, click here. For more general information on a hub's input/output terminals, click here.

Connecting Door Operators

Most door operators connect to the NO and COM terminals on the hub's AUX - DOOR OPERATOR relay. The door operator runs on its own power source but detects the relay's state for operation.

  • Default State (Door Closed): The hub's AUX relay is open, so no action is triggered.
  • Unlock Event Triggered: The hub's AUX relay closes, signaling the door operator to open the door.

Door Hub is used as an example here.

Notes:

Important Reminder: Do Not Use AC-Powered Door Operators

Some older door operators require 12/24V AC, which is not compatible with Access Control Hubs, even with an external transformer. Always use DC-powered door operators.

Common Use Scenario

Automatic door operators are widely used for wheelchair-accessible entrances, ensuring compliance with the Americans with Disabilities Act (ADA), local building codes, life safety standards, and other accessibility regulations. These setups often include button activation, timed door opening, and safety measures to prevent injury.

Common safety considerations for door operators include:

  • Door Hold Time: A door should remain fully open for at least 5 seconds before closing to allow safe passage. Learn more about configuring a door's open duration 

  • Kinetic Energy Limit: A door must move at a regulated safe speed to prevent injury.
  • Force to Prevent Door Movement: The force required to stop a moving door should not exceed 15 lbf (67 N).

Important: Always check local building codes and accessibility regulations to ensure compliance with applicable safety standards.
