SGWCASS-K Door Assist Toilet Door Sensor
Single gang door assist toilet sensor and LED indicator 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 70mm 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.

✔ 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.
✔ Step-by-step checks (de-power system for 10 seconds after each step):
-
Ensure the sensor is securely mounted on the wall, not dangling or handheld.
-
Verify the jumper next to the touch sensor relay is in place and functioning.
-
Use a multimeter to check voltage at the touch sensor (+V and 0V).
-
Ensure 0V is connected to the correct terminal, not the REM terminal.
-
Disconnect the sensor from existing cabling and test it with a short cable directly to the power supply to rule out cable issues.
✔ 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.
✔ 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.
✔ 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.
-
✔ Solution:
-
Verify that the solid/flashing LED jumper on the control board is in place.
-
If using square sensors, the LED wires should connect to the larger outer PCB (see page 10 of the manual).
-
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.
✔ Solution:
-
Change the jumper position on the control board.
✔ Solution:
-
Adjust the potentiometer on the internal touch sensor to switch for 3 – 5 seconds.
-
This may occur if the mag lock contact is intermittently opening and closing 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.
✔ Yes!
-
Multiple Door Assist or Touch to Lock/Open sensors can be wired in parallel for seamless operation.
