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.
