How exterior wildfire defense works

Automated exterior systems track nearby incidents, count down when a fire crosses your trigger distance, then wet roof, eaves, and perimeter before embers arrive.

Typical flow

1. Property inspection measures pressure, elevation, and water sources.
2. Zones are designed for eaves, roof rotors, and ground coverage.
3. Controller watches incidents 24/7; countdown gives a cancel window.
4. If street pressure fails during a run, pool/tank/well can take over (vendor-dependent).
5. Class A foam may be injected to help water soak and stick.

FireShield publishes owner-set distance/countdown, zone selection, scheduling, and multi-path connectivity. Other vendors emphasize IR detection, self-contained tanks, or layered retardant services — see each protocol matrix.
