===== Access – Wiring Diagram (CR00 / CR-D1) =====

The diagram shows the connection of the access module (reader with button and display) to the system via the TGP controller.

The terminal block is divided into functional sections:
  * **DOOR** – connection of the door lock (LOCK, GND) and door contact (DOOR)
  * **PIR** – input for presence sensor (+12V supply and PIR signal)
  * **AUX** – auxiliary inputs/outputs for additional functions
  * **IEX bus** – communication bus (CAN, +24V, GND) for integration with other system devices
  * **DISPLAY** – power supply and communication for the display (VCC, GND, A, B)

The diagram also includes:
  * **DL (door lock)** – example wiring of an electric lock (24V, NO/NC contacts)
  * **Door sensor** – connection of door contact for status monitoring (open/closed)


This diagram defines the basic topology for connecting the access unit, including power supply, door control, presence detection, and communication with the central controller.
