Sure, there could be a few reasons why your B224RB isn’t working as expected. First, check if the base is securely connected to the wiring and if the wiring is intact. Sometimes loose connections or damaged wires can cause issues. Second, ensure that the device it’s controlling (such as a notification appliance) is functioning correctly. If the device is faulty, it might affect the operation of the relay base. Lastly, double-check the programming and settings of the relay base to ensure they are configured correctly for your system. If you’ve checked these steps and still have trouble, it might be a good idea to contact technical support for further assistance.
