GENERAL DESCRIPTION
The GS fire Sprinkler of the ESFR-202 type are fast acting irrigation systems for early fire suppression, having a nominal k-factor 202 (14.0) respectively and operating in fire suppression mode.They are best used as ameans of protecting high-capacitywarehouses without theuseof in-rackirrigationsystems.
NOTICE
The GS fire Sprinkler of the 14.0 K-factor Sprinklers described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of local, in addition to the standards of any other authorities having jurisdiction.
