General
Description
The Series DS-1, 5.6 K-factor, Stand-
ard Response, Standard Coverage,
Dry Type Sprinklers are decorative
5 mm glass bulb automatic sprinklers

quired on dry pipe systems that
are exposed to freezing tempera-
tures (e.g. sprinkler drops from un-
heated portions of buildings)
•
where sprinklers and/or a portion
of the connecting piping may be
exposed to freezing temperatures
(e.g. sprinkler drops from wet sys-
tems into freezers, sprinkler
sprigs from wet systems into un-
heated attics, or horizontal piping
extensions through a wall to pro-
tect an unheated area of a build-
ing)
•
where sprinklers are used on sys-
tems that are seasonably drained
to avoid freezing (e.g. vacation re-
sort areas)
