DESCRIPTION The Viking Standard Response ELO Upright and Pendent Sprinklers are ther- ` mosensitive glass bulb spray sprinklers available in several different finishes and t temperature ratings to meet design requirements. The special Polyester and Teflon° coatings can be used in decorative applications where colors are desired. In addition, these coatings have been investigated for installation in corrosive at- I mospheres and are cULus listed as corrosion resistant as indicated in Approval Chart 1. (Note: FM Global has no approval classification for Teflon(, and Polyester coatings as corrosion resistant.) —_ The extra-large orifice provides greater flows at lower pressures than standard orifice or large orifice sprinklers. This feature allows reduced pipe sizing for hydraulically Upright Pendent calculated sprinkler systems, which require high densities of water. Viking Standard Response Extra-Large Orifice Sprinklers may eliminate the need for a fire pump or reduce the size of the pump if it is required. On existing systems, replacing large orifice sprinklers with extra-large orifice sprinklers may provide the higher densities required to allow an increase in the hazard classification of an occupancy. Viking standard response sprinklers may be ordered and/or used as open sprinklers (glass bulb and pip cap assembly removed) on deluge systems. Refer to Ordering Instructions below. 2.
