Fire Suppression/Detection

Putting out the fire almost before it starts.

Dexter's sensitive yet rugged fire detectors, or fire sensors, serve as the foundation of US combat fire suppression systems on combat aircraft and ground vehicles ranging from the HUMVEE to the Abraham's Tank.  Our fire sensors consume low energy, making them the premier safety component on battery-powered as well as hot-wired systems.  We like to call them "the eye that never sleeps."  How fast are they?  Fast enough to race the fire caused by a rocket hitting a fuel tank and win, triggering fire suppression on the spot to help protect soldier and pilot alike.

Rugged missions require rugged equipment.  Intensive MIL-STD-883H testing performed by Trialon Corporation, an independent testing facility, confirm that Dexter Research's silicon-based temperature sensor detectors meet the same rugged requirements of 1,000G's for mechanical shock and 30G's in random vibration for which our thin-film detectors are famous.  Download Dexter's report here (PDF).
