I understand your concern, Ethan. Unfortunately, the Notifier LDM-R32 has unique specifications, and as of now, there is no direct replacement available in the market. However, I recommend reaching out to Notifier or their authorized distributors for any potential updates on compatible replacements in the future. In the meantime, it might be worth considering a system upgrade or consulting with a professional technician to explore alternative solutions tailored to your specific requirements. If you have any more questions, feel free to ask.
