Description

The F1S5-FS56 and F1S5-FS42 Flat Spray Sprinklers are designed for installation in accordance with CEA 4001 or EN 12845 (Automatic Sprinkler Systems – Design, Installation and Maintenance). The spray pattern created by this sprinkler makes this an excellent choice for applications with lower clearance above the suspended open ceilings and in racks. The F1S5-FS56 and F1S5-FS42 Flat Spray Sprinkler with shield are used in applications where there are high and lower level sprinklers. The shield is to help prevent the lower level sprinklers from getting wet by the higher level sprinklers. The F1S5-FS56 and F1S5-FS42 Flat Spray Sprinkler utilize a special response frangible 5.0mm glass bulb. The glass bulb consists of an accurately controlled amount of special fluid hermetically sealed inside of a precisely manufactured glass capsule. This glass bulb is specially constructed to provide fast thermal response. At normal temperatures, the glass bulb contains the fluid in both the liquid phase and in the vapor phase. The vapor phase can be seen as a small bubble. As heat is applied, the liquid expands forcing the bubble smaller and smaller as the liquid pressure increases. Continued heating forces the liquid to push out against the bulb, causing the glass to shatter, opening the waterway and allowing the deflector to distribute the discharging water. The F1S5-FS56 and F1S5-FS42 Flat Spray Sprinkler temperature rating are identified by the color of the glass bulb capsule (see the table bellow).

Installation

Models F1S5-FS56 and F1S5-FS42 Flat Spray Sprinklers are special response sprinklers intended for installation as specified in CEA 4001 and EN 12845. They must also be installed with the Model D Sprinkler Wrench specifically designed by Reliable for use with these sprinklers. When installing Models F1S5-FS56 and F1S5-FS42 Pendent with shield use the Model GFR2 Sprinkler Wrench. Any other type of wrench may damage these sprinklers. Note: A leak tight ½” NPT sprinkler joint can be obtained with a torque of 10,8 – 24,4 N-m. Do not tighten sprinklers over maximum recommended torque. It may cause leakage or impairment of the sprinklers.
