I still fail to see the issue here. As long as the appropriate number of appliances were turned out to the job, I don't see any issue with the command car responding.
Multiple alarm activations over a small time period need to be handled by the OIC attending. If people are working (sanding/cleaning etc) in the zone, perhaps its best to isolate it until such work is finished, if there is an obvious malfunction, perhaps then it too needs to be isolated until a servicing company can be called to fix the issue. There are many things that the attending brigades can do to stop the multiple activations in a day.
Its good of Barker to provide a great example for us right now, that not ALL AFA's are false.
