I've been searching for additional keypads for a while now with very little luck. I have 3 systems including 2 Channel Plus MDS-6 and a KUSTOM 6640. The systems both use the same keypads, MCS-1, MCS-2, KHS6S, or KHS6D.

Unfortunately, the newer keypads for the MDS-6A system are not compatible. I've spoken to both Channel Plus and KUSTOM, but haven't had much direction other than to upgrade to new systems. With the size and investment of what I have, that's a hard pill to swallow.

Please PM me if you have, or know of some available.

Thank you VERY much!
Tony
