Basic ADA Wiring

Wiring an ADA (Americans with Disabilities Act) automatic door operator into a PDK access control system can vary depending on the hardware setup. One common and simple setup allows the PDK system to control all door locking, while the ADA motor only handles door opening. In this configuration, the ADA system does not control the locking hardware directly.

To implement this setup, you'll need two (2) available relays on a PDK controller.

Port 1 – Outside ADA Button to ADA Motor

• Purpose: Activates the ADA Motor from the outside via a push button.
• Wiring Instructions:
  • Connect the Outside ADA Push Button to the ADA Motor.
  • Wire the button using a dry contact:
    • Connect to the C (Common) and NO (Normally Open) terminals.
    • Do not install a jumper across the BUS.

Port 2 – Access Control & Inside Activation

• Purpose: Controls the locking hardware and inside activation.
• Wiring Instructions:
  • Wire the PDK Reader, Inside ADA Push Button, and door locking hardware (strike or maglock) to this port.
  • Additionally, connect the Inside ADA Button to the ADA Motor, allowing it to activate the door independently from the access system.

Configuring Group Event Rule

Once the ADA motor and push buttons are wired to the PDK controller, you’ll need to configure a Group Event Rule to coordinate door unlocking with ADA activation.

This rule ensures that when access is granted, the ADA motor is triggered to open the door automatically, while the PDK system unlocks the door.

Configuring System Event Rule

Adding a System Event Rule is necessary to support Request to Exit (REX) triggered by the Inside ADA Button.

This rule ensures that when a REX event occurs, the door unlocks and the ADA motor is activated to open the door.

NOTE: Any Auto Open Rules applied to the Door Device must be applied to the IO Device
