TY-FRFS, TY-FS Special and TY-FS Flat Spray Sprinklers

Because of the flat spray pattern, these sprinklers can be used with low clearance above suspended open ceilings and in racks. The TY-FRFS features a 3-mm, heat-sensitive bulb and is designed for quick response. The TY-FS with its 5-mm, heat-sensitive bulb is rated standard response. The TY-FS Special is categorized as special response and has a 4-mm, heat-sensitive bulb. Each model has three upright and pendent versions: 57, 80, or 115 K-factor. Sprinklers with an 80 or 115 K-factor can be outfitted with guards and/or shields to protect against damage.
