Single Gang Toilet Door Assist Sensor & LED Indicator

Colour

Our Toilet Door Assist Sensor is designed for seamless assisted entry, combining modern hygiene, user safety, and robust design. Featuring a scratch resistant, antimicrobial acrylic label, this sensor integrates with our Toilet Locking Control Board (WCPCB) to offer effortless, contactless door activation.

When the toilet is vacant, the blue LED illuminates. A simple touch or wave within the activation range, automatically opens the door for entry. If the facility is engaged, the red LED indicates that the sensor is disabled, ensuring privacy and security.

The entire surface is treated with an antimicrobial protection, which eliminates 99.9% of germs, including Flu Virus, E. coli, MRSA, Salmonella, and Legionella, as well as black mould, biofilm, and fungi. It works continuously to prevent microbial growth before it appears, reducing unpleasant odours, staining, and costly maintenance. This antimicrobial layer also protects the product against degradation, extending its lifespan in high-traffic environments.

For added safety and compliance, the sensor includes a key override for emergency entry. Making it ideal for accessible and public washrooms where reliability and safety are paramount.

Benefits –

Touch or touch free operation (adjustable up to 70mm) for improved hygiene.
LED status indicator – Blue for vacant, red for engaged.
Scratch-resistant acrylic surface with antimicrobial protection.
Continuous germ, mould, and odour prevention for a cleaner environment.
Reduced maintenance cycles and long product life due to antimicrobial surface protection.
Key override for emergency entry and added safety.
Seamless integration with WCPCB for assisted toilet entry systems.

▪ Internal sensor beeps when touched but doesn’t lock the system

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.
See troubleshooting document for more information.

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

▪ Touch sensor doesn’t beep when touched

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.

▪ System Locks With No One Inside

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.

▪ Automatic door doesn’t open when it should

Solution:

Remove the two wires from the C and NO door activation terminals on the control board and join them together.
If the door still doesn’t open, the problem lies with the operator—contact the supplier/manufacturer.

▪ System Goes RED But Maglock Doesn’t Engage

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.

▪ Touch Sensor LEDs Aren’t Lit

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.

▪ Touch Sensor LEDs Flashing but I Want Solid Light

Solution:

Change the jumper position on the control board.

▪ Door Re-locks Instantly After Unlocking

Solution:

Adjust the potentiometer on the internal touch sensor to switch for 3 – 5 seconds.
This may occur if the mag lock contact is 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.
