Interesting, as getting quotes to re-due parts of my system, a dealer mentioned changing the C4-FPD120 at the bottom of my garage stairs to a programable keypad with three buttons for scenes, such as Lights, Home, and Away. However, he didn't mentioned anything about changing out the C4-KA.
I assume that the C4-KA in the hallway can be switched out for a C4-KC120277?
Thank you, as this is why I asked on this forum--getting too much conflicting information with my onsite walkthrough quotes.
