Many thanks; quite understand.

Many thanks, Datadiffusion, for the speedy reply; that helps to know. The next question is how to get the s/w update(s) as I found that Cooper Security/ Scantronics do not talk to non-professional installers...

Earlier in the year I installed an I-on40 and two keypads, type KP-01. I had a problem after a month of two whereby the keypads beep indicating 'Duplicate Entry.' I tried replacing the keypads, but this did not resolve the issue. I had thought that it might be caused by line termination. It worked for several months, with one -the furthest away- terminated and the other unterminated, but the 'Duplicate Entry'; has returned. KP1 is located about 1 meter away from the I-on40; KP2 is located about 10 meters away. KP1 is set to address 4; KP2 to address 2. The error occurs whether I try setting or unsetting the I-on40 either manually, by typing in the code, or by using a fob. The I-on40 has s/w version 4.03.09 and the two keypads are at verison 3.11. Any suggestions, please?
