RWCHLOCK Round Contactless Toilet Indicator Lock – Hygienic, Secure & Modern Access

✔ Solution:

• Link out the door switch terminals on the control board.

• If this works, inspect the mag lock reed switch/monitoring wiring and armature plate alignment.

• Ensure the mag lock provides a normally closed (NC) signal when the door is shut

✔ Step-by-step checks (de-power system for 10 seconds after each step):

1. Ensure the sensor is securely mounted on the wall, not dangling or handheld.

2. Verify the jumper next to the touch sensor relay is in place and functioning.

3. Use a multimeter to check voltage at the touch sensor (+V and 0V).

4. Ensure 0V is connected to the correct terminal, not the REM terminal.

5. Disconnect the sensor from existing cabling and test it with a short cable directly to the power supply to rule out cable issues.

✔ Solution:

• Ensure mag lock contacts are wired into the door switch terminals on the control board.

• Adjust the potentiometer on the internal touch sensor to switch for 3 – 5 seconds.

• Reduce the sensitivity of the internal touch sensor, especially if emergency lighting or hand dryers are nearby.

• Remove any excess cable inside the touch sensor back box.

• Re-terminate internal touch sensor connections.

✔ Solution:

1. Remove the two wires from the C and NO door activation terminals on the control board and join them together.

2. If the door still doesn’t open, the problem lies with the operator—contact the supplier/manufacturer.

✔ Solution:

• Check the position of the override keyswitch on the external sensor.

• Ensure the break glass hasn’t been pressed.

• Inspect the lock fuse.

• Link out the NC & KS/BG terminals on the control board.

  • If the system works after linking, but your keyswitch and break glass are correctly positioned, there is likely a cable break.

• Use a multimeter to check for voltage at the mag lock.

  • If voltage is present but the lock isn’t engaging, the lock is faulty.

✔ Solution:

• Verify that the solid/flashing LED jumper on the control board is in place.

• If using square sensors, the LED wires should connect to the larger outer PCB (see page 10 of the manual).

• Use a multimeter to check voltage at the touch sensor LED terminals.

  • The LEDs have a separate power supply from the sensor itself—if the sensor beeps but LEDs don’t light, check for a cable break.

• Remove the sensor from the wall and connect it directly to the control board using a short cable to rule out wiring issues.

✔ Solution:

• Change the jumper position on the control board.

✔ Solution:

• Adjust the potentiometer on the internal touch sensor to switch for 3 – 5 seconds.

• This may occur if the mag lock contact is intermittently opening and closing while the touch sensor is still beeping.

• Check armature alignment and ensure the door does not judder when opening.

• If the issue persists, replace the mag lock or install a standard magnetic door contact instead.

✔ Yes!

• Multiple Door Assist or Touch to Lock/Open sensors can be wired in parallel for seamless operation.
