Hello Brian, thanks for reaching out. Unfortunately, there is no direct replacement available for the Edwards 8240H fire alarm panel. Edwards has discontinued this model, and finding an exact match can be quite challenging. I recommend contacting our technical support team at firealarm.com for further assistance. We might be able to help you find a compatible alternative or provide guidance on upgrading your system to a newer model that meets your requirements. Feel free to get in touch with us, and we’ll do our best to assist you.
