If a fire developed would a second Automist Smartscan head activate?

All residential suppression systems are not designed to deal with arson which is the only scenario where multiple fires in different locations within a single property are expected. 

However, Automist uses so little water that, if after the 30 minutes standard run time, the sensor pics up that the fire is still present it will reactivate. At this point, a traditional system may have exhausted a tank.
