Tips: Many customers wonder if using our fog will set off their smoke detectors or sprinkler systems. Typically this is only a problem with optical type detectors, because they sense the small water-based particles as smoke. As for sprinkler systems, they are usually triggered by heat, so fog would not set off heat-activated sprinkler systems. We do not advise disabling your smoke detectors or sprinkler systems.
