Application

The Reliable Model F4FR Concealer is the most versatile stan-

dard response sprinkler available. The Model F4FR Standard

Response Concealed Sprinkler provides the best form of fire

protection by offering an attractive appearance and ½” (13mm)

cover adjustment for ease of installation. The small diameter

cover plate is easily and positively attached and blends into the

ceiling, concealing the most dependable fire protection avail-

able, an automatic sprinkler system.

The Concealer®is designed for use where aesthetic appear-

Product Description

The Concealer®for standard response applications uses a

3mm diameter glass bulb in a standard style sprinkler frame

with a drop-down deflector. This assembly is recessed into the

ceiling and concealed by a flat cover plate. The cover plate and

sprinkler cup assemblies are attached using a strong threaded

engagement. This threaded engagement provides ½” (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 subsequent shattering of

the sprinkler bulb opens the waterway and causes the deflec-

tor to drop into position to distribute the discharging water. Any

secure engagement between the cover plate and cup will as-

sure that the drop-down deflector 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-cor-

rosive applications.

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 25/8” diameter hole is cut in the ceiling, the sprinkler

is to be installed with the Model G4 Wrench. When installing a

sprinkler, the wrench is first positioned into the sprinkler/cup as-

sembly until two wrench tangs fully engage 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.

Thesesprinklers mustbe installed,beforetheceilingis inplace

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 INSTALLED ONLY WITH A 135°F RATED COVER.

Maintenance

The Model F4FR should be inspected quarterly and the sprin-

kler 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 damaged in any way. A stock of

spare sprinklers should be maintained to allow quick replace-

ment of damaged or operated sprinklers. Prior to installation,

sprinklers should be maintained in the original cartons and

packaging to minimize the potential for damage to sprinklers

that would cause improper operation or non-operation.
