Touch-Free WC Occupancy Indicator with Antimicrobial Protection

The RWCHASS-K Round Contactless Toilet Indicator Sensor provides a hygienic, modern, and user-friendly solution for managing accessible toilets, washrooms, and changing facilities. Designed to eliminate the need for physical contact, the sensor uses advanced touch-free technology to clearly indicate occupancy status with highly visible red and blue LED illumination.

Simply present a hand within the activation range and the system will switch between engaged and vacant modes, helping to improve hygiene while providing a clear visual indication for users. With no moving parts or mechanical switches, the RWCHASS-K offers enhanced reliability and reduced maintenance compared to traditional toilet door indicators.

To further support hygiene-sensitive environments, the acrylic label incorporates antimicrobial technology proven to reduce up to 99.9% of bacteria, mould, and biofilm growth. This makes the system particularly suitable for healthcare facilities, commercial washrooms, educational buildings, hospitality venues, and public sector environments.

Designed with installers in mind, the sensor operates from a 12–24V DC hardwired supply and offers a sensing range of up to 70mm. Its robust construction and straightforward installation make it an ideal choice for both new projects and refurbishment programmes.

Combining touch-free operation, antimicrobial protection, and modern aesthetics, the RWCHASS-K delivers a practical and professional solution for today’s washroom and accessible toilet environments.

▪ 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 mag lock does not 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.
