DESCRIPTIONAND OPERATION
The Globe Model JN Residential Concealed Pendent Sprinkler is a low profile yet durable design which
utilizes a 3mm frangible glass ampule as the thermosensitive element. It features both economy, aesthetics
and low water flow. The combination of the 3mm frangible glass ampule and specially designed deflector
make the Model JN Residential Concealed Pendent Sprinkler the ultimate in life safety and fire control.
This residential sprinkler has met the strict requirements of Underwriters Laboratories Inc. as described
in the UL Standard, UL I626, for Residential Sprinklers for Fire Protection Service, and should be used
accordingly. These sprinklers should also be installed in accordance with the appropriate NFPA Standard
I3R or 13D.
All that is seen at the ceiling is a 3 5/16" diameter ceiling plate color finished to match the .specifier's
exact requirements. Globe's Residential Concealed Pendent Sprinkler utilizes its pendent residential type
sprinkler which is concealed from view by a dome shaped ceiling plate that conceals the sprinkler just below
the ceiling line for faster response once the ceiling plate has fallen away. The ceiling plate is soldered to
the sprinkler's special upper support assembly in three places. Upon the application of sufficient heat, the
plate falls to the floor exposing the residential pendent spray sprinkler. At the ampule's rated temperature,
the sprinkler opens discharging water onto the floor in its required and approved distribution pattern.
A special spring is attached to the residential pendent sprinkler deflector that serves to provide a
constant tension against the ceiling plate. This feature virtually ensures freedom from environmental
vibration problems.
The patented seat design consists of an engineered plastic seat and silicone o -ring. This combination
has advantages over other types of seating arrangements, in that the plastic seat is an insulator which
provides for no heat loss from the bulb to the water in the system, resulting in faster response. In addition,
the plastic seat is not subject to corrosion or deterioration by chemicals, bacteria or electrolysis.
