Elk M1G 1 button press arm

So I am installing an Elk system in my condo and I want to have both the "away" and "stay" bottons on the keypad to just start the arming countdown when you press them on the keypad (M1KP2). Right now when I press it, it just makes a beep and does nothing. I have to enter a code to start the arm sequence right now. I can't seem to find the option in RP to change this. I know it can do this because my house with the same system (also installed by me) has been single button press arming for years.

Anyone know what I need to change?

In RP, under Area #, check for [x] single keypress quick arm.

Will this still do the countdown?

Yes. It only changes it from a quick double-press to a single press.

That did the trick. Thanks!
