Criteria
The following general guidelines pro-
vided for the TYCO Model ESFR-34
Pendent Sprinklers can be used for a
quick reference�
FM Global Property Loss Prevention
Data Sheet 2-0, “Installation Guide-
lines for Automatic Sprinklers”, pro-
vides the installation guidelines for
the TYCO K33�6 sprinkler under the
heading of Storage Sprinkler, whereas
FM Global Property Loss Prevention
Data Sheet 8-9, “Storage of Class 1,
2, 3, 4 and Plastic Commodities”, pro-
vides its design guidelines� In all cases,
the appropriate FM Global installation
standard must be referenced to ensure
applicability and cannot be substituted
by other codes or standards� Table B
provides a summary of the design
and installation guidelines provided in
Data Sheets 2-0 and 8-9; they are not
intended to provide complete installa-
tion criteria�
