The invention provides a new type double-track double-curtain fire resistance rolling shutter door, comprising two same rolling shutter door bodies, double-groove guide rails, fire resistance rolling door machines, first reels and second reels, automatic sprinkler protection devices, and a controller, wherein the upper end of each rolling shutter door body is respectively fixed on a first reel and a second reel, two sides of the rolling shutter door body are installed in the double-groove guide rails and can move up and down; each automatic sprinkler protection device comprises a first water pipe fixed at the bottom of the outside of a fire resistant box cover and connected with a fire-prevention pipe, a plurality of rotatable shower nozzles are arranged on the first water pipe for realizing water spraying protection, a magnetic valve is connected between the first water pipe and the fire-prevention pipe; the controller is located at the same side where the fire-prevention pipe is loacated, and is connected with a temperature sense probe in a matching manner, the on-off of the magnetic valve is controlled by a relay according to temperature variation. The automatic sprinkler protection devices are additionally installed at the tops and two sides of the rolling shutter doors, so that not only is the temperature of the rolling shutter door lowered, but also the role of fire active fighting is realized, and the fire behavior extending to the direction of the rolling shutter door is slowed down.
