The TOPENS TC175P wired keypad is an advanced access control device that utilizes RFID technology for convenient, contactless gate entry. Users can operate the gate using either a password or a RFID card, eliminating the need for traditional keys. With its enhanced security features, the TC175P provides a reliable and keyless entry solution.
If you are experiencing issues with your TC175P wired keypad, follow the troubleshooting steps below to identify and resolve the problem.
1. Unusual Noise in Standby Mode
If the TC175P keypad produces unusual noises while in standby mode, this is often due to interference. Common sources include power fluctuations, nearby wireless signals, or strong radiation. Ensure that high-power wireless devices are kept away from the keypad to prevent disruption. If no interference is found and the noise continues, the keypad itself may be faulty.
2. Keypad Not Responding or Not Functioning Properly
Step1: Check Wiring Connections
Ensure all wiring is securely and correctly connected. If you are unsure, refer to the TC175P wiring diagram in the "Connection of Accessories" section of you gate opener's Installation Manual.
Step 2: Check the keypad
Dim or unlit key backlight may indicate a hardware issue. To test functionality, press each key and listen for sound feedback - for example, when entering the default password "123456", each key should produce a sound, confirming it has registered.
Step 3: Set the Access Password
Enter the "access password #" to operate the gate, if the keypad is set to "Password" or "Password or Card" mode. The factory default password (123456) is for setup only and cannot be used for gate access. To set a new access password (3-6 digits), refer to the TC175P user manual or the article "How to Use the TOPENS TC175P Wired Keypad". Please note that only one Common Access Password can be set, and it can be changed but not deleted unless the keypad is reset to factory settings.
Step 4: Check the RF Indicator
After entering the access password, observe the RF indicator light on the keypad. If the indicator turns solid green, continue to the next step. If not, verify the password or try setting a new one. If the issue persists, record a video showing the indicator's status after password entry and send it to our technical support team for further diagnosis.
Step 5: Check for Interference Between Wired Accessories
Disconnect all wired accessories from the control board and test the keypad. If the keypad functions properly when connected alone but malfunctions when other wired accessories are connected, this may indicate an interference between them. In this case, connect the signal wires of the TC175P and the other accessories in parallel, and then connect them to the control board. Using shielded cables and grounding the keypad’s COM terminal can help minimize electrical interference.
If the problem persists, or if no other accessories are connected, proceed to the next step.
(Example: Connect the TC148 Waterproof Wall Push Button and TC175P Wired Keypad in Parallel)
Step 6: Inspect the Extension Cable
Remove any extension cable between the keypad and the control board. Reconnect the keypad using its original wires. If this resolves the issue, check the size and length of the extension cable. The recommended cable size is 4C x 0.3 mm² (22AWG), with a maximum length of 5 meters (16 feet). For longer distances (up to 30 meters/100 feet), use thicker shielded cables. If the problem continues, try decreasing the Relay Unlock Output time by 1-2 seconds to reduce the delay.
Step 7: Verify the Power Source
Connect an external 12-24VDC power supply directly to the keypad (instead of using the control board's power). Then reconnect the signal wires to the control board and test the keypad again. If the gate still does not open, proceed to the next step.
Step 8: Test the Control Board
If all previous steps have been completed and the keypad still doesn't operate the gate, test the control board by briefly shorting the terminals for the wired push button (insert and immediately remove the wire). If the gate does not respond, the control board may be faulty and should be replaced.
By carefully following these troubleshooting steps, you should be able to resolve most issues related to the TOPENS TC175P wired keypad. If the problem persists, please contact our technical support team for further assistance or consider replacing any defective components.
