Application

The Reliable Model G4A

Concealer®is the most versatile

quick response concealed sprin-

kler available. It provides the best

form of fire protection while

offering an attractive appearance

and ½²(13mm) of cover adjust-

ment for ease of installation. The

small diameter cover plate as-

sembly is easily attached and

blends into the ceiling, concealing

the most dependable fire protec-

tion available, an automatic

sprinkler system.

The Model G4A Concealer®is designed for use where

aesthetic appearance is important. Offices, hospitals, motels

and restaurants 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 G4A Concealer®is a UL Listed Quick Response

Concealed sprinkler intended for use in accordance with NFPA

13. FM Approves this sprinkler as a standard response

concealed sprinkler intended for use in accordance with FM

Loss Prevention Data Sheet 2-8N.

Product Description

The Reliable Model G4A Concealer®uses a proven quick re-

sponse fusible element 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 assembly. The threaded

engagement provides ½²(13mm) of cover adjustment. The flat

cover plate is attached to the skirt using either 135°F (57°C) or

165°F(74°C) ordinary temperature classification solder.

When the ceiling temperature rises, the solder holding the flat

cover plate melts, the flat cover plate released thus exposing

the sprinkler inside to the rising ambient temperature.

The subsequent fusing of the element opens the waterway

and causes the deflector to distribute the water. Any secure

engagement between the cover plate and cup will assure that

the drop-down deflector is properly located below the ceiling.

Installation

Do not install the G4A Concealer®in ceilings which have

positive pressure in the space above.

•Cut a 258inch (67mm) diameter hole is cut in the ceiling, the

sprinkler is easily installed with the Model G4 Wrench. The

wrench has drive tangs which insert into the cup slots.

When installing a sprinkler the wrench is first positioned into

the sprinkler/cup assembly until the wrench tangs engage

the drive slots in the top of the cup (there are two sets 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.

Install the cover plate by hand turning the cover in the

clockwise direction until it is tight against the ceiling.

A protective cap is provided to protect the drop-down sprinkler

deflector from damage which could occur during construction

before the cover plate is installed. The cap is factory installed

inside the sprinkler cup. Remove cap to install sprinkler, then

re-install cap until the cover plate is installed.

Maintenance

The Model G4A Concealerâshould 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 damaged in any way. A

stock of spare sprinklers should be maintained to allow quick

replacement 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.
