Desciption

The Reliable Model JL-14 Early Suppression Fast Response (ESFR) Sprinkler is intended for use against severe fire challenges. This sprinkler is designed to respond quickly to growing fires and will deliver a heavy water discharge to “suppress” rather than “control” fires.

The Model JL-14 ESFR sprinkler utilizes a levered fusible alloy solder link in either a 74°C or a 100°C rating. FM Global considers this a “Quick Response” storage sprinkler for use in Data Sheet 8-9. The sprinkler has a Nominal K Factor of 14.0 (metric 202) and will deliver approximately 100 gpm (378 L/min) of water at 50 psi (3,5 bar). The deflector and frame provide a broad, very symmetrical, hemispherical pattern capable of suppressing fires between sprinklers in high storage height areas and at the same time retaining a high momentum central core to penetrate and suppress fires occurring directly beneath the sprinkler in low storage height areas.

Design Criteria

Sprinkler Position: Pendent, align frame arms with the pipe. Deflectors should be parallel with the ceiling or roof

Max. slope celling: 9,5°
Max. spacing: 3,7m () for building heights up to 9,1m), 3,1m ( for building heights greater than 9.1m)
Min. spacing: 2,4m
Deflector distance from walls: At least 102mm from walls, and no more than one-half the allowable distance permitted between sprinklers
Deflector to Top of Storage: Min. 914mm
Deflector to ceiling Distance: 152-356mm per NFPA 13, 121-356mm per FM 2-2.
Center Line of Thermal Sensing Element To Ceiling Distance: 102-330mm per FM
