HOW TO STORE MORE THAN 500
USER KEYS
In particular applications, it may be necessary to
store more than 500 user keys.
In this case, use the 1102/52 (2000 keys) memory.
Replace the standard key memory with the new
memory, proceeding as follows:
− switch off the door opener module;
− open the rear cover and carefully extract the
standard memory device, exerting leverage on
both sides with a small screwdriver;
− insert the new memory device, paying particular
attention to the direction of insertion, as shown

At power-up, the door release module automatically
recognizes the higher capacity memory without
requiring any further operations.

and 1999; the central decimal point will
indicate keys between 2000 and 2999.

key No. 560
key No. 1502
