1. DESCRIPTION

The Viking Micromatic
mosensitive, glass-bulb spray sprinkler available in several different finishes and tem-
perature ratings to meet design requirements. The special
Nickel PTFE (ENT) 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 listed/approved as corrosion resistant as indicated in the Approval
Charts. (Note: FM Global approves the ENT coating as corrosion resistant. FM Global has
no approval classification for Polyester coatings 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
