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.
