1. DESCRIPTION
Viking Micromatic
®
and MicromaticHP
®
Standard Response Pendent Sprinklers are
small, thermosensitive, glass-bulb spray sprinklers available in several different fin-
ishes, temperature ratings, and K-Factors 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
atmospheres and are cULus listed as corrosion resistant as indicated in the Approval
Chart. (Note: FM Global has no approval classification for Teflon
®
and Polyester coat-
ings as corrosion resistant.)
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 on page 11b.
