Will my oven or burnt cooking set off the system?
No, the iMist system can only be activated by genuine fire temperature. The bulbs used in our system are the same that are used in fire suppression systems all over the world.In the films, all the nozzles/heads go off at once, will this happen in my house?
No, that is a Hollywood myth. It will only be the nozzle where the fast response bulb breaks that will be activated in the unfortunate event of a fire.
