Description
TYCO Series DS-1 Dry-Type Sprinklers,
5.6K Pendent, Upright, and Horizontal
Sidewall, Quick Response (3 mm bulb)

tive glass bulb automatic sprinklers

dry pipe systems that are exposed
to freezing temperatures (e.g.,
sprinkler drops from un heated
portions of buildings)

connecting piping are exposed to
freezing temperatures; for example,
sprinkler drops from wet sys tems
into
freezers,
sprinkler
from wet systems into unheated
attics, or horizontal piping exten-
sions through a wall to protect an
unheated areas such as loading
docks, overhangs, and building
exteriors
• sprinklers are used on sys tems that
are seasonally drained to avoid
freezing (e.g., vacation areas)
