Defender One Fire Fighting Systems

Fire Combat’s Defender One Portable firefighting system

Fire Combat’s Defender One is a trailer mounted, mobile, automatic fire detection and suppression system. It offers totally independent, self-contained, unmanned fire fighting capability within the range of the detector and discharge turret. The Defender One can perform temporary standby duty like a manned fire truck, or substitute for a limited water sprinkler system in enclosed spaces.

The Defender One fire fighting trailer boasts a microprocessor-based controller, multi-sensor flame detection, a 500-gallon agent tank, nitrogen expellant, an automatic oscillating discharge turret, a manual handline hose, and a 12VDC battery power source with solar panel recharging capabilities.

Once deployed, this fire fighting unit’s flame detector continuously monitors the hazard area, discriminating between true fire emergencies and false alarms. In case of fire, the agent tank pressurizes, audio/visual alarms activate, a radio signal is dispatched (when transceiver equipped), and the turret begins to oscillate and sweep to discharge AFFF solution onto the fire. The self-sealing AFFF not only knocks down and suppresses flame, it also covers any spilled fuel to prevent reflash.
