How would you set up MagicinfoPro to display emergencies such as a fire? For example we would need to have "Fire, get out of the building" displayed immediately. I suppose I would pre-make a template, but then i would have to manually edit the schedule and upload the new template, of which that could take at least 30 seconds to 1 minute for the TV's to reflect the change. Please advise the best way to do this.
