SQWCASS-K Door Assist Toilet Indicator Sensor
Square illuminated toilet occupancy indicator and assisted door touch sensor with scratch resistant anti microbial acrylic label.
Used with our toilet locking control board (WCPCB), the touch sensor is installed on the outside of the facility and used to gain assisted entry. When the facility is vacant with the blue LED illuminated, the user touches the sensor and the automatic door will open. If the toilet is engaged, shown by the red LED, the sensor will not work and the toilet will remain locked.
The sensitivity is adjustable from touch to 50mm hands free, making it very hygienic. If touched SteriTouch® offers protection against a range of bacteria, including the Flu Virus, E. coli, MRSA, Salmonella and Legionella, as well as black mould growth, biofilm and fungi. SteriTouch® works continuously and effectively to restrict this growth before it appears. It eradicates the bacteria which cause contamination and infection, as well as those responsible for odours and staining. The antimicrobial effect also protects the product against degradation, extending its use!
Comes with key over-ride for emergency entry.

-
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.
