OK, but I'm really a Napco man.
If it works for you that's fine. I'm just used to teaching people to enter their code and then select what they want the panel to do. It's as natural to me as doing it your way is to you.
I'm sure that's true. By reading the manual and actually installing the system they become far more knowledgeable than the average alarm user. I'm sure you've had as many clients as I have (when I was still installing) who don't understand the first thing other than "punch in the code and the little red light comes on." However, I've trained hundreds of non-DIY alarm users to operate the alarms we installed over the years and IME they don't have much trouble grasping the use of the keypad. It's mostly a matter of me doing a thorough job of teaching them (not as though you don't of, course).
Perhaps, but consider this. Hundreds of thousands of alarm owners use both methods and they rarely cause false... hmmm, errm scratch that. :^)
