General
Description
The Central Model H, 5.6 K-factor
Recessed Pendent Sprinklers are
automatic sprinklers of the fusible solder
type. They are standard response -
standard orifice spray sprinklers
intended for use in fire sprinkler
systems designed in accordance with
the standard installation rules recog-
nized by the applicable Listing or
Approval agency (e.g., UL Listing is
based on NFPA 13 requirements).
The Central Model H Recessed
Pendent Sprinklers incorporate a center
strut mechanism with a special two-
piece recessed escutcheon assembly
permitting 1/2" of field-adjustment.
Unlike most other recessed sprinklers,
the upper escutcheon support piece is
factory installed on the base of the
sprinkler frame, assuring a Listed
Installation. The ceiling escutcheon
plate is easily installed after the
sprinkler is in place either by the
standard "push-on" escutcheon or the
special "thread-on" escutcheon. This
feature allows removal of ceiling panels
for easy access to ceiling equipment
without taking the system out of service
to remove the sprinkler.
Operation: A fusible alloy is sealed into
a bronze actuating rod (center strut) by
a 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 Recessed Pendent
Sprinklers described herein must be
installed and maintained in compliance
with this document, as well as with the
applicable standards of the National
H
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 maintain-
ing their fire protection system and
devices in proper operating condition.
The installing contractor or sprinkler
manufacturer should be contacted
relative to any questions.
