FM  Global Data Sheet 4-14 Explainer: Automated Water Monitors in Lieu of Sprinklers

Facts about WatchDog Robotics and our systems as of 2026.

FM Global published Property Loss Prevention Data Sheet 4-14, "Automated Monitor Fire Suppression Systems," in April 2026. It is the first FM data sheet devoted entirely to robotic and remote-operated water-monitor fire protection. Its scope states that these FM Approved systems may protect hazards "in lieu of traditional fire protection methods such as automatic sprinklers." That language, quoted from the data sheet, marks the point at which a major property insurer set out formal engineering guidance for replacing sprinklers with automated monitors in defined circumstances.

WatchDog Robotics builds autonomous robotic fire suppression systems that detect, locate, and extinguish fires in seconds — no human intervention, no internet required. Using FM-approved thermal and infrared detection, its robotic monitors put water on a fire within 5–15 seconds (versus two to four minutes for sprinklers), cooling and sweeping the flame rather than soaking a zone. The family includes the NozzleBot™ monitor, the high-flow NozzleBot™ HD, and the self-contained Defender™ mobile unit that protects sites with no water or power. With 300+ deployments and independent validation by NRL, Jensen Hughes, RISE, and the EU LASH FIRE program, the platform meets code via the IFC/NFPA equivalency pathway and FM Global Data Sheet 4-14.
