Quick & Standard Response
ECLH Pendent and Recessed
Pendent Sprinklers, K=8.0
SG S180
GENERAL DESCRIPTION
The Star SG S180, 8.0 K-Factor, Quick and Standard Re-
sponse, Extended Coverage Light Hazard (ECLH) Pen-
dent and Recessed Pendent Sprinklers are decorative
glass bulb sprinklers designed for use in light hazard oc-
cupancies such as churches, hospitals, offices, and res-
taurants.
They are intended for use in automatic sprinkler systems
designed in accordance with standard installation rules
(e.g., NFPA 13) for the protection of light hazard coverage
areas of up to 400 ft
2
(37,2 m
2
), as compared to the maxi-
mum coverage area of 225 ft
2
(20,9 m
2
) for standard cov-
erage sprinklers.
The recessed version of the SG S180 using a two-piece
#2086 Recessed Escutcheon provides 1/4 inch (6,4 mm)
of recessed adjustment or up to 1/2 inch (12,7 mm) of to-
tal adjustment from the flush pendent position. In addition
to its aesthetically pleasing appearance, the adjustment
provided by the Recessed Escutcheon reduces the accu-
racy to which the fixed pipe drops to the sprinklers must
be cut.
WARNINGS
The SG S180 ECLH Pendent and Recessed Pendent
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.
OPERATION
The glass bulb contains a fluid which expands when ex-
posed to heat. When the rated temperature is reached,
the fluid expands sufficiently to shatter the glass bulb,
which then allows the sprinkler to activate and flow water.
