Hello. A customer inherited a Trigon Model 100 Door entry system. Found programming instructions on line, minus the password. Called Trigon and tech said the 100 is such an old model he didn't have the reference. Another tech may, but I have to call in the afternoon (Pacific) to ask. Seems like I can never find the time (Central) and was wondering if anybody here may know the beginning access code. Appreciate any help to [email protected]. THankx
