Hi there,
We’ve had experience with this exact scenario, and I can assure you that the Notifier SWL-BP10 is fully compatible with systems previously using the System Sensor SW notifier. Notifier has ensured backward compatibility with their newer offerings, making the transition seamless for users. You should be able to swap out the old notifier with the new one without any issues. If you have any specific concerns or questions during the installation process, feel free to reach out, and we’ll be happy to assist you further.
