The Auto Fire-Tite® IMB has the same features as the Fire-Tite® IMB with controlled automatic closing by one of Alpine’s Redi-Reset Motor hand chain or crank options. The Auto Fire-Tite® IMB can be connected to smoke detectors and fire alarms as well as any building alarms. The Redi-Reset operators eliminate the complication of a manual reset of the door after drop testing or activation. The Auto Fire-Tite® IMB is also labeled for up to 4 hours of fire protection by UL and NYC MEA.

Auto Fire-Tite® IMB curtains are constructed of galvanized steel and can be finished with powder coating or baked enamel finishes. The metal on metal insulated slats have a 7/8" foamed-in-place urethane core which bonds the metal skin and strengthens the slat. Each door is equipped with a 22 gage steel hood formed to fit the contour of the end brackets. Durable ductile iron endlocks with 1/4" semi-solid rivets. Our door supports and brackets are all steel plates no less than 1/4" thick. Alpine's Torsion Counterbalance Assembly is state of the art, providing maximum security and ease of use.
