Application
The Reliable Model F4FR
Concealer is the most versatile
quick response sprinkler available.
The Model F4FR Quick Response
Concealed Sprinkler provides the
best form of fire protection by offer-
ing an attractive appearance and
½²(13mm) cover adjustment for
ease of installation. The adjustable
1²NPT inlet versions have one and
one half inches of total adjustment, and they also eliminate
the need for a reducing coupling. The small diameter
Product Description
The Concealer®for quick response applications uses a
135°F (57°C) 3mm diameter glass bulb in a standard style
sprinkler frame with a drop-down deflector. This assem-
bly is recessed into the ceiling and concealed by a flat
cover plate. The cover plate and sprinkler cup assem-
blies are attached using a strong threaded engagement.
This threaded engagement provides ½²(13mm) of cover
adjustment. The cover plate is attached to the skirt using
135°F (57°C) ordinary temperature classification solder.
When the ceiling temperature rises, the solder holding the
cover plate fuses, thus releasing the plate and exposing
the sprinkler inside to ambient temperature. The subse-
quent shattering of the sprinkler bulb opens the waterway
and causes the deflector to drop into position to distribute
the discharging water. Any secure engagement between
the cover plate and cup will assure that the drop-down de-
flector is properly located below the ceiling.
Note: The cup and skirt are fabricated from corrosion re-
sistant plated steel and are intended for interior
non-corrosive applications.

cover plate is easily and positively attached and blends
into the ceiling, concealing the most dependable fire pro-
tection available, an automatic sprinkler system.
The Concealer®is designed for use where aesthetic ap-
pearance is important. Offices, hospitals, motels and res-
taurants are but a few of the applications where it can be
used. It is available in different orifice sizes allowing the
designer to optimize system performance, thereby
achieving a very efficient installation.
The Model F4FR Concealer is a quick response concealed
sprinkler intended for use in accordance with NFPA 13.
The Concealer®can eliminate the need for precise cut-
ting of drop nipples. The threaded cover plate assembly
can be adjusted without tools to fit accurately against the
ceiling. The fire protection system need not be shut down
to adjust or remove the cover plate assembly.

Installation
Do not install The Concealer®in ceilings which have
positive pressure in the space above. In addition, inspect
all sprinklers after installation to ensure that both the gap
between the cover plate and ceiling and the 4 slots in the
cup are open and free from any air flow impediment.
After a 258
²diameter hole is cut in the ceiling, the sprin-
kler is to be installed with the Model G4 Wrench. When in-
stalling a sprinkler, the wrench is first positioned into the
sprinkler/cup assembly until two wrench tangs fully en-
gage drive slots in the top of the cup (there are two pairs of
drive slots in the cup). The sprinkler is then tightened into
the pipe fitting. When inserting or removing the wrench
from the sprinkler/cup assembly care should be taken to
prevent damage to the sprinkler. DO NOT WRENCH ON
ANY OTHER PART OF THE SPRINKLER/CUP ASSEMBLY.
The equipment presented in this bulletin is to be installed in accordance with the latest pertinent Standards of the National Fire Protection Association, Factory Mutual Research
Corporation, or other similar organizations and also with the provisions of governmental codes or ordinances whenever applicable.

Finishes (1):
The adjustable inlet versions are similar to the standard
Model F4FR except that an additional 1²of adjustment is
provided by means of a telescoping inlet section that
threads in or out of a stationary coupling reducer (either 1²
NPTmaleor1²NPT female) as shown in Figures 2 or 3.
These sprinklers must be installed, before the ceiling is in
place by wrenching on only the coupling reducer hex
flats. After the ceiling has been installed, each telescoping
inlet section is to be adjusted with the G4 Wrench. Final
adjustment of each cover is made by hand turning the
cover in the clockwise direction until it is tight against the
ceiling. THE MODEL F4FR CONCEALER MUST BE IN-
STALLED ONLY WITH A 135°F RATED COVER.
Maintenance
The Model F4FR should be inspected quarterly and
the sprinkler system maintained in accordance with NFPA
25. Do not clean sprinklers with soap and water, ammonia
or any other cleaning fluids. Remove any sprinkler that
has been painted (other than factory applied) or dam-
aged in any way. A stock of spare sprinklers should be
maintained to allow quick replacement of damaged or op-
erated sprinklers. Prior to installation, sprinklers should be
maintained in the original cartons and packaging to mini-
mize the potential for damage to sprinklers that would
cause improper operation or non-operation.
