Hi Rachel, thanks for reaching out. Unfortunately, the Edwards 3-XFP is a specialized model with unique features, and there is no direct replacement available for it. Edwards designed the 3-XFP for specific applications, and finding an exact replacement might be challenging. However, if you’re looking for an upgrade, I recommend consulting with a certified fire alarm system provider to assess your requirements and suggest a compatible modern system. Feel free to ask if you have any more questions!
