Description
TYCO Series DS-1 Dry-Type Sprinklers,
5.6K Pendent, Upright, and Horizontal
Sidewall, Standard Response (5 mm

decorative glass bulb automatic sprin-
klers typically used where:
• pendent sprinklers are required on
dry pipe systems that are exposed to
freezing temperatures; for example,
sprinkler drops from
portions of buildings
• sprinklers and/or a portion of the
connecting piping may be exposed to
freezing temperatures; 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, over-
hangs, and building exteriors
• sprinklers are used on systems that
are seasonably drained to avoid
freezing; for example, vacation resort
areas
