FAAST XT
FAAST XT brings all the capabilities of FAAST – such as three stage filtration, Very Early Warning Fire Detection, and several integration options – to a broader range of applications. The smoke-sensing chamber can detect particulate up to 0.00046%/ft obscuration, and the two-light chamber offers increased accuracy and nuisance immunity. FAAST XT can cover up to 28,800 square feet in Standard Detection, and has an aggregate pipe length of 1,050 feet.
