TYCO Series DS-1 5.6K Pendent, Upright, and Horizontal Sidewall, Standard Response (5 mm bulb), Standard Coverage Dry-type Sprinklers are decorative glass bulb automatic sprinklers typically used where:
- Pendent sprinklers are required on dry pipe systems that are exposed to freezing temperatures; for example, sprinkler drops from unheated 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, or horizontal piping extensions through a wall to protect unheated areas of a building such as loading docks, overhangs, and building exteriors).
- Sprinklers are used on systems that are seasonably drained to avoid freezing (for example, vacation resort areas).
