Alarm control keypads

[Joe Doakes <jodo@xxxxxxxxxxx>]

Does anyone know of a source for numeric keypads to replace the simple
key switches that control my alarm system?  The alarm is a DTI model DSS
51/52.  The current switches are operated with a round key.  Several
years ago I found programmable keypads that would directly replace the
switches but I decided not to get them at the time.  The store is now
out of business, and I havn't had much luck searching the web.


Thanks in advance

Joe
