Dry Horizontal Sidewall Sprinklers
Luminous™ S176, 5 mm Bulb
GENERAL DESCRIPTION
The Star Luminous S176, 5.6 K-Factor, Standard Re-
sponse, Standard Coverage, Dry Horizontal Sidewall
Sprinklers are decorative glass bulb automatic sprinklers
designed for use in applications where the sprinklers
and/or a portion of the connecting piping may be exposed
to freezing temperatures (e.g., horizontal piping exten-
sions from a wet pipe sprinkler system through a wall to
protect a freezer or unheated area of a building).
The Luminous S176, 5 mm Bulb, Dry Horizontal Sidewall
Sprinklers are “standard response - standard orifice
spray sprinklers” and are available in a wide range of op-
erating temperatures and order lengths. The Luminous
S176 Sprinklers are intended for use in fire sprinkler sys-
tems designed in accordance with the standard installa-
tion rules recognized by the applicable Listing or Ap-
proval agency (e.g., UL Listing is based on NFPA 13
requirements).
They are designed for installation along a wall and just be-
neath a smooth ceiling. Installed with their centerline of
waterway horizontal, these sprinklers produce a quarter-
spherical water distribution pattern that is predominately
directed downward and outward from the sprinkler with a
portion of the spray being directed towards the backwall.
The Standard Escutcheon for the Luminous S176 is a
separable two-piece design which allows installation of
the sprinklers and pressure testing of the fire protection
system, prior to wall construction and/or application of a
finish coat to the wall. It also permits refinishing of a wall
surface without having to first shut down the fire protec-
tion system and remove the sprinklers.
WARNINGS
The Luminous S176 Standard Response, Dry Horizontal
Sidewall Sprinklers described herein must be installed
and maintained in compliance with this document, as well
as with the applicable standards of the National Fire Pro-
tection 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 S176 Standard Response, Dry Horizontal
Sidewall Sprinklers must only be installed in fittings that
meet the requirements of the Design Criteria section.
OPERATION
When the Luminous S176 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.
