Note: Specific wire colors and functions may vary slightly. Always consult the wiring diagram provided with your specific access control panel.
5.3 Mounting Steps
- Drill appropriate holes for mounting screws and cable routing at the chosen location.
- Feed the reader's cable through the wall/mullion.
- Secure the reader to the surface using the provided mounting hardware.
- Connect the reader's wires to the access control panel as per the wiring diagram.
- Apply power to the access control system and test the reader.
6. Operation
Once installed and powered, the ARD-AYK12 card reader is ready for operation.
6.1 Presenting a Card
To gain access, present a valid EM proximity card directly in front of the card reader. The optimal reading distance may vary slightly depending on the card type and environmental factors.
6.2 LED and Beeper Feedback
The reader provides visual and audible feedback:
- Green LED: Typically indicates access granted or reader idle.
- Red LED: Typically indicates access denied or an error state.
- Beeper: A short beep usually confirms a successful card read. Multiple beeps or a continuous tone may indicate an error.
Note: The exact behavior of the LED and beeper can be configured via the access control panel.
7. Maintenance
The Bosch ARD-AYK12 card reader requires minimal maintenance to ensure long-term performance.
- Cleaning: Periodically wipe the reader's surface with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Inspection: Regularly inspect the reader for any signs of physical damage or tampering. Check cable connections for integrity.
- Firmware: Firmware updates, if available, should only be performed by authorized service personnel.
8. Troubleshooting
If you encounter issues with your ARD-AYK12 card reader, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reader does not respond (no LED, no beep) | No power; faulty wiring; reader malfunction. | Check power supply to the access control panel. Verify wiring connections. If problem persists, contact support. |
| Card read but access denied | Invalid card; card not enrolled; access control panel configuration issue. | Ensure the card is valid and enrolled in the access control system. Check access control panel settings. |
