Why is the locking device always unlocked on my Kaba RAC 4XT IP Access Controllers?
- J
  Jonathan WilsonAug 23, 2025
  If the locking device on your Kaba IP Access Controllers remains unlocked, it could be due to several reasons. If the Locking Device Relay LED (D31) on the RAC4XT controller is ON, check if the delay setting of the DIP switch (SW2) is correct and confirm that the lock is not in Passage Mode. If the Locking Device Relay LED (D31) is OFF, ensure that the Bypass switch is not active (Bypass LED, D21, is OFF), verify that the Fire Alarm input is not active (Input contact closed, Fire Alarm LED, D47, is ON), and check the wiring to the locking device.

  If the locking device of your Kaba IP Access Controllers isn't unlocking, and the Locking Device Relay LED (D31) turns on, first ensure that the Fire Alarm input is not active (check if the Input contact is closed and the Fire Alarm LED, D47, is on). Next, verify the wiring to the locking device and, if a diode is installed, check its polarity. If the Locking Device Relay LED (D31) does not turn on, confirm that activating the Request to Exit or Remote Unlock unlocks the door, verify that the card is encoded correctly, ensure that the RAC 4XT is not in Lockout mode, and confirm that the RAC 4XT is programmed correctly.

  If all the LEDs on your Kaba IP Access Controllers RAC 4XT are off, begin by verifying that the DC ON LED on the power supply is lit. Then, check that AC power is active for the wall mount power adaptor. Also, ensure the RAC 4XT controller is properly connected to the power supply. If you are qualified, use a multi-meter to verify that 24 VAC (North American power adaptor) or 24 VDC (international power adaptor) is present across power supply terminal block XFMR_1 and XFMR_2.
