Sprinkler Head 74 Deg. C (165F), ESFR Pendent, 3/4" NPT, Fast Response, Fusible Type, K- Factor 16.8 (241.9), Bronze, SIN RA1914, Model: JL-17 ESFR, P/N.# DB16114998, UL/FM Approved - Reliable

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.
