The STI-1100 consists of a clear, tamperproof, polycarbonate cover, frame and piezo horn that fits over most manual pull fire alarm stations. When the cover is lifted, a piercing 95- or 105-decibel warning horn sounds, drawing attention to the immediate area. The cover is connected to the frame by a cable. The horn will sound until the cover is snapped back onto the frame (or for the life of the battery). The cover is UV-stabilized and features a lifetime guarantee against breakage of the polycarbonate in normal use. The device is UL-listed to U.S. and Canadian safety standards, and it is FM-approved.
