Since this is a user to user forum. Don't expect instant answers. Give it some time.
Also the SC1200A is relatively new and most have not started mods yet.
#1 NO it has no RF transmitter in it. So disarm on the SC1200A will not register in OnAlert. Not sure if the consloe arm sending the light codes on and off to the power lines can be used for telling OnAlert it was armed.
