Replacement Keypad for Old Ademco 4127 Keypad

Hi,
I'm looking for a replacement keypad for an Ademco 4127 keypad connected to an Ademco 4120EC Panel that was installed in the early to mid 1990's. Does anyone remember that far back?
Thanks your for your help.

Gerald

Fortunately, Ademco (now Honeywell) has continued making its new keypad models back-compatible with its earlier model Panels. I think Honeywell/Ademco is the only brand whose contempory KPs are compatible with early-90's Panels (actually, late 80's, with the introduction of the Vantage/Vista generation of Panels).

A Honeywell/Ademco 6150 Keypad will replace your 4127 KP. When you get it, look at the KP's Installation instructions and be sure to address it to Address 31. Otherwise, your 4120EC Panel won't understand it.
