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.

  • See troubleshooting document for more information.

Note: On RTR mag locks the black & green flying leads connect to the door switch terminals on the WCPCB.

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.

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.

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 going open & closed circuit 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.
