Kidde Fire Protection SystemsDual Spectrum® Optical Infrared Sensor Model PM-3MT

Dual spectrum infrared sensors detect fuel explosions and fires in enclosed spaces of armored personnel carriers. They are operational in any lighting condition and effective through oil, smoke, dirt and other obscurants.

These sensors evaluate the growth level of the fire event. By determining the rate of fire growth, fire protection system sensors are able to mitigate false alarms.

UTC Aerospace Systems provides fire and explosion sensors that utilize a patented infrared detection concept. These sensors respond to explosive fires in milliseconds and have excellent false alarm immunity.

Features

• Evaluate the growth level of the fire

• Excellent false alarm immunity

• Effective in obscurant environment

• Responds to explosive fires in milliseconds
