Use the sprinklers in wet-pipe, dry-
pipe, or preaction systems based on
the following criteria:
• On dry pipe systems that are
exposed to freezing temperatures,
for example, sprinkler drops from
unheated portions of buildings
• When sprinklers and/or a portion
of the connecting piping may be
exposed to freezing tempera-
tures, for example, sprinkler drops
from wet systems into freezers,
sprinkler sprigs from wet systems
into unheated attics, or horizontal
piping extensions through a wall to
protect unheated areas of a building
such as loading docks, overhangs,
and building exteriors
• On systems that are season-
ably drained to avoid freezing, for
example, vacation resort areas
