Wiring

The MCOC-43 is a wireless battery-powered sensor and does not require external signal wiring.

  • Power: Internal battery
  • Input: Door/window opening detected by the magnetic contact
  • Output: 433MHz wireless alarm signal
  • Other Connections: Wireless pairing with a compatible 433MHz alarm control panel

Programming

  1. Open “Parts” from the alarm panel Main Menu.
  2. Select “Detector”.
  3. Tap “+ Add”.
  4. Select “Door Alarm” under Name.
  5. Align the two parts of the door sensor.
  6. Separate the two parts to activate the sensor.
  7. The alarm panel should detect the wireless sensor.
  8. Save the sensor after successful pairing.

Operation

  1. Keep the door/window closed with the sensor and magnetic contact properly aligned.
  2. When the door/window opens, the two parts separate and the sensor transmits an alarm signal.
  3. The compatible alarm panel receives the signal and activates the programmed alarm/notification response.

Troubleshooting

  • Problem: Sensor is not detected by the alarm panel
  • Solution: Confirm that the alarm panel supports 433MHz and that the sensor has been correctly added through the panel's detector menu.
  • Problem: Alarm does not trigger when the door opens
  • Solution: Check the alignment and distance between the two sensor parts. Separate them during testing to trigger the sensor.
  • Problem: Wireless range is weak
  • Solution: Reduce obstacles between the sensor and alarm panel. The specified 120m range applies to open space without obstacles.
  • Problem: Sensor stops working
  • Solution: Check or replace the CR2450 battery and verify that the sensor is still correctly paired with the alarm panel.

Common Problems

  • Wrong frequency – Confirm that the alarm system supports 433MHz.
  • Incorrect sensor alignment – Reposition the sensor and magnet so they are correctly aligned.
  • Sensor not paired – Add the sensor through the alarm panel's Parts → Detector → + Add menu.
  • Weak signal – Move the sensor closer to the alarm panel or reduce physical obstructions.
  • Low battery – Replace the CR2450 battery when the battery voltage becomes low.
