Product Description

The Reliable Model J168 Automatic sprinkler utilizes
the center strut solder in compression principle of con­struction. The fusible alloy is captured in the cylinder
of the solder capsule by a stainless steel ball. When
the fusible alloy melts, the ball moves into the cylinder
allowing the cylinder to separate from the center strut.
When this happens, the lever is released to spring free
from the sprinkler so that all operating parts clear the
waterway allowing the deflector to distribute the dis­charging water in a hemispherical pattern.

The Reliable Model J168, 16.8 K-factor sprinklers
were tested in full scale fire tests to qualify them for the
protection of rack and high piled storage.

Design Criteria

FM Approval Requirements

The Reliable Standard Response standard spray J168,
K-16.8 Upright Sprinkler is approved to be installed in ac­cordance with FM Data Sheets 8-9 and 2-0. (FM guide­lines may be different from UL and C-UL Listing criteria).

cULus Listing Requirements

The Reliable Standard Response J168 Upright Sprinkler
is cULus Listed for use in occupancy classifications up
to and including Extra-Hazard, for hydraulically calculated
wet or dry systems per NFPA 13, with a minimum operat­ing pressure of 7 psi (48,3 kPa) in wet or dry systems. Use
the standard sprinkler positioning requirements and den­sity/area sprinkler protection criteria provided in NFPA 13.

Also:

The J168 Sprinkler is cULus Listed for use in High-Piled
Storage Occupancies as defined in NFPA 13. This sprin­kler may be used for the protection of solid piled, pallet­ized, rack storage (single, double, multiple-row and por­table), bin box, and shelf storage including, but not limited
to: encapsuled or unencapsulated Class I-IV and Group
A or B plastics, cartoned, expanded or unexpanded, as
well as exposed unexpanded. For hydraulically calculated
wet or dry systems per NFPA 13 with a minimum operat­ing pressure of 7 psi (0,5 bar). Use the standard sprinkler
positioning requirements and density/area sprinkler pro­tection criteria provided in NFPA 13 for High-Piled Storage
Occupancies.
Refer to NFPA 13 for specific requirements for various
combinations of building heights, storage heights, sprin­kler- to-commodity clearance, storage arrangements,
commodity classifications, and lesser or greater required
design densities.
Note: The J168 Sprinkler can be used in any application
or building height as allowed by NFPA13 or FM guide­lines. The J168 is a standard response standard spray
sprinkler with a larger K factor to provide greater water
flows at lower pressures.
