Description

The F156, F142, F1XLH & F128 Series Glass Bulb Sprinkler combines the durability of a standard sprinkler with the attractive low profile of a decorative sprinkler. Whether installed on exposed piping or in an office ceiling, it is functional and attractive. Beautifully versatile is the description for the Reliable Models F156, F142, F1XLH & F128 Series Recessed glass bulb sprinkler. Recessing the F156, F142, F1XLH & F128 Series enhances its already low profile decorative appearance, and facilitates a rapid and perfect installation. The nozzles are functional and good-looking as well as directly to the bare piping the suspended ceiling or wall mounted.

F1-series of sprinklers has a 5 mm glass capsule. The glass bulb consists of an accurately controlled amount of special fluid hermetically sealed inside 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 glass capsule color indicates the sprinkler trigger temperature (see the Table on the bottom of the page).

Application areas

F1 Series sprinklers are used in fixed fire protection systems: Wet, Dry, Deluge or Preaction.

Installation

When installing Model F156, F142, F1XLH & F128 Recessed Sprinklers use the Model GFR2 Sprinkler Wrench. Any other type of wrench may damage these sprinklers. A leak tight ½” NPT (R1/2) 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
