Hello Emily, thank you for reaching out. I understand your concern. Unfortunately, there is no direct replacement available for the Edwards Signaling 3045-W. It’s an older model, and newer technologies have replaced it in the market. However, I recommend consulting with a certified technician to assess your current system and explore potential alternatives that can work seamlessly with your existing setup. They might be able to suggest compatible components or an updated system that meets your requirements. If you have any more questions, feel free to ask.
