Hey Emily, great choice with the Kidde KI-PD! To install it, start by mounting the base on the ceiling or wall. Make sure it’s secure and aligned properly. Then, connect the wiring following the provided instructions—typically, there are color-coded wires for an easier setup. Once connected, attach the smoke detector to the base. Don’t forget to test it after installation to ensure it’s working correctly. If you have any specific concerns during the process, feel free to ask for more guidance. Good luck with your installation!
