Description
The Reliable Models JL14 and JL17 are Early Suppression Fast Response (ESFR) Sprinklers with nominal K-factors of 14.0 (200 metric) and 16.8 (240 metric), respectively. The sprinklers use a levered fusible alloy solder link in either a 165°F (74°C) or a 212°F (100°C) temperature rating. These sprinklers are designed to respond quickly to growing fires and will deliver a heavy water discharge to “suppress” rather than “control” fires.
FM Approvals classifies the Model JL14 and JL17 as quick response sprinklers, storage and non storage, when used in accordance with FM Global Property Loss Prevention Data Sheets.
Model JL14 and JL17 ESFR sprinklers are designed to be shorter and more compact than other ESFR sprinklers, allowing greater flexibility with regard to distance from ceilings and obstructions. The JL14 and JL17 ESFR sprinklers are also less susceptible to damage due to smaller deflector and frame design. The lighter JL14 and JL17 ESFR sprinklers passed rough use and abuse listing tests without plastic protectors.
