What could be the potential problem? February 4, 2022 at 1:45 pm #5846 Brad Weeks Make sure “Access” is not checked under User Authorization for the User Code you’ve entered under ElkLink February 4, 2022 at 1:47 pm #5847 David Lim confirmed that any other ideas? February 4, 2022 at 2:15 pm #5849 Brad Weeks The User Code should have Area 1 checked, Arm and Disarm. The other options do not need checked. Make sure in Globals G29 – G42 all six Serial Port 0 Options are checked. Does the User Code match the last 4-digits of the Local Keypad Installer Code?
