SQWCHASS-K Contactless Toilet Indicator & Touch Sensor: Seamless Hygiene and Efficiency

£108.25 EX VAT

Contactless Toilet Indicator with Antimicrobial Protection

This innovative square contactless toilet indicator features a scratch-resistant, antimicrobial acrylic label and operates with a simple hand approach. When activated, the switch triggers red and blue LEDs to indicate whether the restroom is engaged or vacant. It is powered by a versatile 12-24V DC power source.

Key Features:

  • Contactless Operation: Activation range of up to 70mm for touch-free operation, ensuring hygienic use.

  • Antimicrobial Protection: The label is protected by SteriTouch®, an additive that kills 99.9% of germs, including harmful bacteria such as E. coli, MRSA, Salmonella, and the flu virus.

  • Prevents Mould Growth: SteriTouch® helps prevent mould, biofilm, and fungi growth, which can cause costly redecoration cycles and respiratory issues, especially in damp environments.

  • Long-lasting Protection: The antimicrobial effect works continuously to prevent bacterial contamination, eliminate odours, and protect against staining and degradation, extending the life of the product.

  • Clear Status Indicators: Red and blue LEDs clearly indicate whether the restroom is engaged or vacant, ensuring quick, intuitive use.

✔ 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):

  1. Ensure the sensor is securely mounted on the wall, not dangling or handheld.

  2. Verify the jumper next to the touch sensor relay is in place and functioning.

  3. Use a multimeter to check voltage at the touch sensor (+V and 0V).

  4. Ensure 0V is connected to the correct terminal, not the REM terminal.

  5. 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:

  1. Remove the two wires from the C and NO door activation terminals on the control board and join them together.

  2. 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.
