Quick Response
Extended Coverage
Horizontal Sidewall Sprinklers
SuperNova™ S124
K=5.6, 1/2" NPT
GENERAL DESCRIPTION
The Star SuperNova S124, 5.6 K-Factor, QR-EC Horizon-
tal Sidewall Sprinklers are quick response - extended cov-
erage, fusible solder type spray sprinklers designed for
use in hydraulically calculated sprinkler systems in light
hazard, commercial occupancies such as churches, res-
taurant seating areas, hotels, educational facilities, of-
fices, etc. With coverage areas up to 16 feet (4,9 m) wide
by 20 feet (6,1 m) long, they are designed for installation
along a wall or the side of a beam and just beneath a
smooth and level ceiling. Horizontal sidewall sprinklers
are commonly used instead of pendent or upright sprin-
klers because of aesthetics or building construction con-
siderations, where piping across the ceiling is not desir-
able.
WARNINGS
The SuperNova S124 Sprinklers described herein must
be installed and maintained in compliance with this docu-
ment, as well as with the applicable standards of the Na-
tional Fire Protection Association, in addition to the stand-
ards 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 fusible link (heat collector) assembly is comprised of
two link halves which are joined together by a thin layer
of solder. When the rated temperature is reached, the sol-
der melts and the two link halves separate, which then al-
lows the sprinkler to activate and flow water.
