▪ Sensor Beeps but Doesn’t Lock the System

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.

▪ 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 Maglock Doesn’t 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:

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.

▪ Touch Sensor LEDs Flashing (Want Solid Light)

Solution:

Change the jumper position on the control board.

▪ Door Re-locks Instantly After Unlocking

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.
