- 1 x Installation Guide (Printed or Digital)
- Mounting Hardware (Screws, anchors, etc.)
Setup and Installation
Proper installation is crucial for optimal performance. Follow these steps carefully:
- Site Selection: Choose a mounting location that provides clear line-of-sight to the intended read area and is protected from severe weather conditions if installed outdoors.
- Mounting:
- Secure the mounting bracket (if applicable) to the wall or pole using the provided hardware.
- Attach the R90 reader to the mounting bracket, ensuring it is firmly in place.
- Wiring:
- Connect the reader's wiring harness to the access control panel according to the wiring diagram provided in the separate installation guide. Pay close attention to power (VDC), ground (GND), data lines (Data 0, Data 1), and LED control lines.
- Ensure all connections are secure and insulated.
- Power On: Apply power to the access control system. The reader's indicator light should illuminate, typically red or green, indicating power and readiness.
Operating Instructions
The HID iCLASS R90 reader operates by reading iCLASS credentials presented within its read range. The operational status is indicated by the integrated LED.
- Credential Presentation: Present a compatible iCLASS credential (card, fob, etc.) within the reader's effective read range. The optimal range will vary based on environmental factors and credential type.
- Indicator Light:
- Red: Indicates power is applied and the reader is in standby mode.
- Green (or flashing): Indicates a successful read and data transmission to the access control panel.
- Note: Specific LED behavior may be configurable via the access control system.
- Data Transmission: Upon a successful read, the reader transmits the credential data to the connected access control panel via the Wiegand interface. The panel then processes the data to grant or deny access.
Maintenance
The HID iCLASS R90 reader is designed for minimal maintenance. Regular cleaning and inspection can help ensure long-term reliability.
- Cleaning:
- Gently wipe the reader's surface with a soft, damp cloth.
- Do not use abrasive cleaners, solvents, or harsh chemicals.
- Ensure no liquid enters the device.
- Inspection: Periodically check the mounting and wiring connections for any signs of wear, corrosion, or loosening.
- Firmware Updates: Consult your access control system administrator or HID support for information on available firmware updates, which may improve performance or add features.
Troubleshooting
If you encounter issues with your HID iCLASS R90 reader, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Reader not powering on (no LED light) | No power supply; faulty wiring; damaged reader. | Check power connections and source. Verify wiring to the access control panel. If issues persist, contact support. |
| Reader not reading credentials | Incompatible credential; credential too far; interference; faulty reader. | Ensure credential is iCLASS compatible. Present credential closer to the reader. Check for nearby metallic objects or strong RF sources. Test with a known good credential. |
| Reader reads, but access is denied | Access control panel issue; credential not enrolled; incorrect permissions. | Verify credential enrollment in the access control system. Check user permissions and time schedules. Consult the access control panel's manual. |
If the problem persists after attempting these solutions, please contact HID Global technical support.
