Description

Reliable Models F1FR LO-series Recessed Sprinklers are quick response sprinklers which combine the durability of a standard sprinkler with the attractive low profile of a decorative sprinkler. The Models F1FR LO and F1FR LO Recessed automatic sprinklers utilize a 3.0 mm frangible glass bulb. These sprinklers have demonstrated response times in laboratory tests which are five to ten times faster than standard response sprinklers. This quick response enables the Model F1FR LO and F1FR LO Recessed sprinklers to apply water to a fire much faster than standard sprinklers of the same temperature rating. 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. The balance of parts are made of brass, copper and beryllium nickel. At normal temperatures, the glass bulb contains the fluid in both the liquid and vapor phases. 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 temperature rating of the sprinkler is identified by the color of the glass bulb.

Installation

Sprinklers have orange capsule protectors(or hidden model protective cap) to protect the glass capsule during transportation, handling and installation. The glass capsule protector is removed after installation. Removing protection prematurely may expose the sprinkler damage. Capsule protector is removed by opening them by hand. Avoid using the tools, so do not damage the glass capsule.

Sprinklers must be installed in by the purpose-designed Reliable nozzle wrench. The right key types can be found in the data sheet. Tight connection is obtained by tightening the sprinkler torque of 11-24 Nm. Do not tighten the sprinklers above the recommended torque. The documented higher torque will not improve sealing, it can in fact cause leaks and damage the sprinkler.
