- Open the Doorbell Cover: Carefully open the cover of your existing wired doorbell control box.
- Connect the Transmitter: Connect the wires from the wireless transmitter to the terminals of your doorbell control box. There is no distinction between positive (+) and negative (-) poles for this connection. Ensure the voltage is within the 3-24V AC/DC range.
- Test Connection: After connecting, press your wired doorbell button. The LED on the transmitter should light up, and if a receiver is plugged in and paired, it should ring, indicating a successful connection.
- Secure the Transmitter: Secure the transmitter inside the doorbell control box cover. You may use tape to prevent it from coming loose. Close the doorbell cover. If you have both front and back wired doorbells, you will need a separate extender for each.
