Hi there, Amanda! If you’re looking for a replacement for your Simplex 742-267 control panel, I would recommend considering the Simplex 650-440 or the Simplex 8650-440. Both of these panels are compatible and should meet your needs. Please check your specific requirements and consult your local fire safety regulations to ensure the new panel is suitable for your application. If you have any more questions or need further assistance, feel free to ask.
