Dry Upright Sprinklers
Luminous™ S170, 5 mm Bulb
GENERAL DESCRIPTION
The Star Luminous S170, 5.6 K-Factor, Standard Re-
sponse Dry Upright Sprinklers are glass bulb automatic
sprinklers designed for use where sprinklers and/or a por-
tion of the connecting piping may be exposed to freezing
temperatures (e.g. sprinkler sprigs into unheated attics).
The Luminous S170, 5 mm Bulb, Dry Upright Sprinklers
are “standard response - standard orifice spray sprin-
klers” and are available in a wide range of operating tem-
peratures and order lengths. The Luminous S170 Sprin-
klers are intended for use in fire sprinkler systems
designed in accordance with the standard installation
rules recognized by the applicable Listing or Approval
agency (e.g., UL Listing is based on NFPA 13 require-
ments). They produce a hemispherical water discharge
pattern below the deflector.
WARNINGS
The Luminous S170 Standard Response, Dry Upright
Sprinklers described herein must be installed and main-
tained in compliance with this document, as well as with
the applicable standards of the National Fire Protection
Association, in addition to the standards of any other
authorities having jurisdiction. Failure to do so may impair
the integrity of these devices.
The owner is responsible for maintaining their fire protec-
tion system and devices in proper operating condition.
The installing contractor or sprinkler manufacturer should
be contacted relative to any questions.
The Luminous S170 Standard Response, Dry Upright
Sprinklers must only be installed in fittings that meet the
requirements of the Design Criteria section.
OPERATION
When the Luminous S170 is in service, water is pre-
vented from entering the assembly by the Plug & O-ring
(Ref. Figure 2) in the Inlet of the Sprinkler. The glass Bulb
contains a fluid which expands when exposed to heat.
When the rated temperature is reached, the fluid expands
sufficiently to shatter the glass Bulb, and the Bulb Seat is
released. The compressed Spring is then able to expand
and push the Water Tube as well as the Guide Tube out-
ward. This action simultaneously pulls inward on the
Yoke, withdrawing the Plug & O-ring from the Inlet, which
then allows the sprinkler to activate and flow water.
