SQWCASS-K Door Assist Toilet Indicator Sensor
£108.25 ex VAT
Door assist touch switch & toilet occupancy indicator.
Lock override keyswitch is built into the under side of the back box.
The toilet occupancy indicator sensor is designed for effortless accessibility, clear status indication, and superior hygiene. Paired with our toilet locking control board (WCPCB), it provides a simple and reliable solution for assisted entry into accessible washrooms.
When the toilet is vacant, the blue LED illuminates, indicating the door can be opened with a light touch or a hands free gesture. If the facility is engaged, the red LED signals that the door is locked, and the sensor will remain inactive until it’s free.
To ensure cleanliness and durability, the sensor’s scratch resistant acrylic label is infused with antimicrobial protection, which continuously eliminates 99.9% of bacteria, viruses, and harmful microbes including E. coli, MRSA, Salmonella, Legionella, and the Flu Virus. This built in technology also prevents mould, biofilm, and fungi.
For safety, the unit is equipped with a key override for emergency entry, making it ideal for both commercial and accessible washroom installations.

▪ 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.
â–ª 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
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:
-
Verify that the solid/flashing LED jumper on the control board is in place.
-
Refer to the wiring diagrams section.
-
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.
â–ª Touch Sensor LEDs Flashing (Want Solid Light)
Solution:
-
Change the jumper position on the control board.
â–ª Can I Use Multiple Sensors?
Yes!
-
Multiple Door Assist or Touch to Lock/Open sensors can be wired in parallel.
