Hi Amanda, unfortunately, there is no direct replacement available for the Siemens HFPO-11 fire alarm panel. Siemens has discontinued this model, and finding an exact replacement might be challenging. However, I recommend contacting Siemens directly or checking their official website for information about upgraded models or compatible alternatives. It’s important to ensure compatibility and compliance with local regulations when replacing fire alarm panels. If you need further assistance, feel free to reach out.
