RWCLOCK Round Antimicrobial Touch to Lock Toilet Sensor

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

• If this works, check:

  • Maglock reed switch wiring

  • Monitoring cable

  • Armature plate alignment

• The maglock must provide a normally closed signal when the door is shut.

After each step, power down the system for 10 seconds before restarting.

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

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

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

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

• Bypass cabling by wiring the sensor directly to the power supply using a short lead.

• Confirm the maglock contacts are wired to the door switch terminals on the control board.

• Set the potentiometer on the internal sensor for a 3–5 second delay.

• Reduce sensor sensitivity, especially near emergency lights or hand dryers.

• Remove excess cable from the sensor’s back box.

• Re-terminate all sensor connections.

• Remove the two wires from C and NO terminals on the control board.

• Touch them together:

  • If the door still doesn’t open, the issue is with the door operator—contact the supplier.

• Check 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 with the link in place, and the keyswitch & break glass are in correct positions, there may be a cable fault.

• Use a multimeter to check for voltage at the maglock.

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

• 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.

• Bypass any cabling issues by wiring the sensor directly to the control board with a short cable.

Adjust the LED jumper position on the control board.

• Adjust the internal sensor delay to 3–5 seconds using the potentiometer.

• Check if the maglock contact is flickering while the sensor is still beeping.

• Ensure the armature plate is aligned and the door isn’t juddering on opening.

• Replace the maglock or use a standard magnetic door contact if needed.

• Yes!

  • You can install multiple internal or external touch sensors.

  • Just wire them in parallel.
