Arm and Disarm

I have an Envisalink3 connecting my Vera3 to my DSC 1864. I have loaded the ap, entered the zones and added entered disarm in the status.

When i got to arm and disarm from the buttons under the Partition 1 Device box, i get no result. If i go into settings, enter my pin in the box and then select arm and/or disarm it seems to work. How do i set it up so i can arm/disarm directly from the pinned device?

Thanks in advance for your help!
