A growing number of modular builders are choosing Automist over traditional sprinkler systems to streamline factory construction and improve fire safety in modular homes, prefab builds, and accessory dwelling units (ADUs). Unlike sprinklers, which often require inspectors to see every joint onsite, forcing ceilings and walls to remain open until inspection, Automist offers two alternative pathways that many AHJs accept: factory documentation with pressure testing onsite, or conduit installation for hose pull-throughs onsite. Both methods eliminate the need for extra labor after inspection, keeping finishing work in the factory and accelerating approvals.
Automist also protects homes smarter. Its wall-mounted spray heads use infrared sensors to scan rooms, detect fire, and target the flames directly with a fine water mist. The system only activates if a fire is confirmed, preventing unnecessary discharges and the devastating water damage common with sprinklers. Because it uses just 2.4 gallons per minute, less than a power shower, it avoids the need for bulky tanks or costly mains upgrades. Its dry-pipe design means no antifreeze or heat tracing is required in colder climates, removing the risk of frozen, burst pipes.
With a footprint of just 9 x 7 x 14 inches, Automist takes up far less space than a traditional system that might require 15 square feet. It can be tucked neatly under a sink or into a cabinet, freeing up valuable room in compact modular units. Builders, inspectors, and homeowners alike are finding it to be a safer, smarter, and more efficient way to meet code without compromise.
“I really feel like this system is far superior to standard fire sprinkler systems,” said Matt Fix of Flow Fire Protection in Northern Colorado. “These systems are very effective in taking care of not only alerting people that there is a problem…but also providing that safety egress piece that is so important in getting folks out of the house.”
