Read full descriptionHide full description
FireDefense is the companion app for the Fire Defense Systems exterior sprinkler platform. When wildfire threatens, open or close your property's water-defense valve right from your phone, and keep an eye on active fires near your home. CONTROL YOUR VALVE • See your valve's live status at a glance: ready, running, or offline. • Activate or stop your sprinkler with a deliberate press-and-hold control designed to prevent accidental taps. • Clear feedback tells you whether the valve actually responded, so you're never left guessing. KNOW WHAT'S NEARBY • A live map shows active wildfires around your location, using public data from the National Interagency Fire Center and CAL FIRE. • Adjustable radius from 10 to 100 miles. • Tap any incident for size, distance, containment, and a link to official information. BUILT FOR THE MOMENT THAT MATTERS • Talks directly to your valve over your local Wi-Fi. • No account, no sign-in, no ads, no tracking. • Designed for clarity under stress. FireDefense requires a Fire Defense Systems valve installed at your property. Learn more at firedefense-systems.com.
