This Single Gang No Touch Toilet Sensor provides a contact free solution for locking or unlocking toilet doors, ideal for accessible bathrooms, healthcare environments, and hygiene critical areas. The toilet sensor features an antimicrobial, scratch-resistant acrylic label and is activated by the presence of a hand within 50mm. This ensures a seamless, modern user experience without physical contact.

Powered by 12–24V DC and built with red and blue status LEDs, the toilet sensor provides clear visual feedback when the door is locked or open. If touched, the antimicrobial additive embedded in the surface offers protection against 99.9% of harmful bacteria and mould, helping to reduce odours, prevent degradation, and minimise cleaning cycles.

Key Features Of Our Toilet Sensors:

Contactless Activation
Detects hand movement up to 50mm – no physical contact required.
Red & Blue LED Indicators
Instantly shows locked or open status for user reassurance.
Antimicrobial Protection
Protects against E. coli, MRSA, Salmonella, Legionella, Flu Virus, mould, biofilm, and fungi.
Durable Construction
Scratch-resistant acrylic faceplate designed for heavy use.
Single Gang Size
Standard UK electrical back box fitting for easy installation.
12–24V DC Operation
Compatible with most access control and door automation systems.

The antimicrobial protection not only fights bacteria and viruses, it also prevents black mould growth, which can lead to staining, odours, and costly redecoration. It works continuously to prevent microbial colonisation, helping prolong the life of the sensor and maintain washroom cleanliness.

▪ 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.
