Pendent Fire Sprinkler Head, Quick Response, 1 in, 25.2 K, 212 deg F, Bronze

The Reliable® model N25 Early Suppression fast response sprinkler (ESFR/Quick response storage Sprinkler) is intended for use against severe fire challenges. This sprinkler is designed to respond quickly to growing fires and deliver a heavy water discharge to "suppress" rather than "control." the model N25 ESFR sprinkler utilizes a levered fusible alloy solder link in either a 165 deg F (74 deg C) or a 212 deg F (100 deg C) rating. FM global considers this a "Quick Response" storage sprinkler for use per FM data Sheet 8-9. The sprinkler has a nominal K factor of 25.2 (metric 360). The smaller 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. The N25 ESFR sprinkler is also less susceptible to damage due to smaller deflector and frame design. The lighter N25 ESFR passed rough use and abuse test in the labs without plastic protectors.
