General
Description
The Central Model H Horizontal Sidewall
Sprinklers are standard response -
standard coverage, fusible solder type
spray sprinklers 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 requirements).
Horizontal Sidewall Sprinklers are
generally used in lieu of pendent & upright
sprinklers because of building construction
or installation economy considerations.
They are designed for installation along a
wall or the side of a beam and just
beneath a smooth ceiling. Installed with
their centerline of waterway parallel to the
ceiling, these sprinklers produce a quarter-
spherical water discharge pattern that is
predominately directed downward &
outward from the deflector; however, a
portion of the spray is also directed
towards the backwall.
These sprinklers are available with wax
and lead coatings that may be utilized to
extend the life of copper alloy sprinklers
beyond that which would otherwise be
obtained when exposed to corrosive
atmospheres.
Although wax and lead coated sprinklers
have passed the standard corrosion tests
of the applicable approval agencies, the
testing is not representative of all possible
corrosive atmospheres. Consequently, it is
recommended that the end user be
consulted with respect to the suitability of
these corrosion resistant coatings for any
given corrosive environment. The effects
of ambient temperature, concentration of
chemicals, and gas/chemical velocity,
should be considered, as a minimum,
along with the corrosive nature of the
chemical to which the sprinklers will be
exposed.
Operation: A fusible alloy is sealed into a
bronze actuating rod (center strut) by a
H
stainless steel ball. When the alloy melts
at its rated temperature, the ball is forced
upward into the center strut, releasing the
two ejectors and operating the sprinkler.
WARNING
The Model H Horizontal Sidewall Sprin-
klers described herein must be installed
and maintained 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 protection system and devices in
proper operating condition. The installing
contractor or sprinkler manufacturer
should be contacted relative to any
questions.
