RWCLOCK Round Antimicrobial Touch to Lock Toilet Sensor

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.

Note: On RTR mag locks the black & green flying leads connect to the door switch terminals on the WCPCB.

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

• Ensure the sensor is securely mounted—not dangling or held in hand.

• Check the jumper next to the sensor relay is fitted and making properly.

• Use a multimeter to check voltage across +V and 0V at the sensor.

  • The touch sensor and LEDs use separate supplies – LEDs being lit doesn’t mean the touch sensor side has power.

• Confirm 0V is in the correct terminal, not the REM terminal.

• Disconnect the sensor from existing cabling and connect it directly to the controller on a short piece of cable 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.

• Consider fitting the MULTI-TIMER reset relay.

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:

• Check the LED jumper (solid/flashing) on the control board is in place.

• For square sensors, ensure LED wires are connected to the larger outer PCB (see manual p.10).

• Use a multimeter to test voltage at the LED terminals:

  • The sensor and LEDs use separate supplies—beeping doesn’t mean LEDs have power.

• 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 flickering open & closed circuit 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.
