A fire alarm station pull cover with a rectangular box shape enclosure that is open in the front, back and bottom and has a removable cap. The cover is mounted to a wall fully encasing a fire alarm pull lever. A glass pane resides in grooves on both sides of the apparatus and is supported laterally by said grooves and vertically by a detent at the bottom of each groove. One or a plurality of equi-spaced vertical score mark s formed on the pane of glass causes the pane to controllably break into parts when stru ck by a striker preferably attached by a tether to the cover. The sections of glass fall dow n and out through the open bottom to expose said pull lever and allow actuation of the lever.
