Wont Arm the Panel

The system has 3 sensors and when I Arm the panel it waits there and says my command could not be verifed. I have run communication tests and they passed.

The system cannot arm if the security page on the panel is disabled. It looks like yours is set to disabled.

On your panel go to Settings > Advanced Settings > Enter Installer or Dealer Code > Installation > Installer Settings. Scroll down and enable Security Page.
