DH80 Sprinkler

Products Description

The Model DH80 family of sprinklers are quick response

extended coverage sidewall sprinklers for use in light haz-

ard applications. The Model DH80 with SWC cover plate is

a concealed sprinkler that uses Reliable’s push on/thread off

sidewall cover. This sprinkler has the cup factory mounted

and is shipped with a protective cap that protects the 3mm

frangible glass bulb during shipping and post installation fin-

ishing operations. The DH80 can be combined in the field

with the FP or F2 Escutcheon to make a recessed sprinkler.

The SWC cover plate, FP and F2 recessed escutcheons

have ½” adjustment. The SWC cover plate is attached with

135-degree solder. In the event of a fire the rising ambient

temperature melts the solder and the cover plate is ejected

away by springs exposing the 3mm frangible glass bulb.

The use of a 3mm bulb allows quick response which enables

the sprinkler to apply water to a fire sooner than standard

response sprinkles of the same temperature rating.

Application

The Model DH80 is a horizontal sidewall sprinkler intended

for installation in light hazard occupancies in accordance

with NFPA 13. These sprinklers are designed to provide fire

protection in long and narrow spaces such as hallways, cor-

ridors, decks and rooms up to 28 feet (8,5m) wide and 14

feet (4,3m) long. They are rated for 250 psi (17,2 bar) and

can be mounted between 4 and 12 inches (102 and 305mm)

down from the ceiling.

Installation

DH80 Recessed, FP Escutcheon

To install the DH80 with the FP Escutcheon as a recessed

sprinkler cut a 25

8” diameter hole in the wall as shown in Fig-

ure1. Remove temporarily the plastic protective cap, then

use the GFR1 wrench to tighten the sprinkler until secured in

the sprinkler fitting. NOTE: The GFR1 wrench has a notch in

it to accommodate the deflector top. This wrench can only

be inserted one way. Care must be taken not to damage the

deflector during tightening. Apply a Teflon* based sealant

to the sprinkler threads before installing in the fitting. When

inserting or removing the wrench from the sprinkler cup, care

must be taken to prevent damage to the sprinkler. Wrench

only on the square boss. DO NOT WRENCH ON ANY OTH-

ER PART OF THE SPRINKLER. It is recommended that the

sprinkler be protected during plastering and painting opera-

tions by reinstalling the protective cap P/N 6802710003. In-

stallation is completed by removing the protective cap and

inserting the push-on escutcheon. Turn clockwise to adjust

the escutcheon against the wall.

DH80 Recessed, F2 Escutcheon

To install the DH80 with the F2 Escutcheon as a recessed

sprinkler cut a 2¼” diameter hole in the wall as shown in

Figure 2. Thread the DH80 into the collar hand tight. Apply

a Teflon* based sealant to the sprinkler threads and install

in the fitting. Wrench only on the square boss. NOTE: The

GFR1 wrench has a notch in it to accommodate the deflec-

tor top. This wrench can only be inserted one way. When

inserting or removing the wrench from the sprinkler cup care

must be taken to prevent damage to the sprinkler. DO NOT

WRENCH ON ANY OTHER PART OF THE SPRINKLER. It is

recommended that the sprinkler be protected during plaster-

ing and painting operations by using the protective cap P/N

6999991009. These must be ordered separately. Installation

is completed by removing the protective cap and inserting

the F2 Escutcheon over the collar.

DH80 with SWC Cover Plate Concealed

To install the sprinkler, cut a 25

8” diameter hole into the

wall as shown in Figure1. A Teflon* based thread sealant

should be applied to the sprinkler threads only. Remove

the protective cap (P/N 6802710003) and then position

the GFR1 wrench into the sprinkler/cup assembly until the

wrench engages the flats of the square boss. Then tighten

the sprinkler 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. The protective

caps should be reinstalled for protection during plastering

and painting. Remove caps only when covers are being in-

stalled. The cover assembly is then pushed onto the cup.

Cover assemblies provide ½” (13mm) of adjustment. Final

adjustment is made by turning the cover clockwise until the

skirt flange makes full contact with the wall surface. Cover

removal requires turning in the counter- clockwise direction.

Concealed cover/cup assemblies are listed only for use

with specific sprinklers. The use of any other concealed

cover/cup assembly with the Model DH80 Horizontal Side-

wall Sprinkler or the use of the concealed cover assembly on

any sprinkler with which it is not specifically listed will void all

guarantees, warranties, listings and approvals.

Note: DH80 and DH80 Recessed Sprinklers have orange

bulb protectors to minimize bulb damage during shipping,

handling, and installation. REMOVE THIS PROTECTION AT

THE TIME THE SPRINKLER SYSTEM IS PLACED IN SER-

VICE FOR FIRE PROTECTION. Removal of the protectors

before this time may leave the bulb vulnerable to damage.

RASCO wrenches are designed to install sprinklers when

covers are in place. REMOVE PROTECTORS BY UNDOING

THE CLASP BY HAND. DO NOT USE TOOLS TO REMOVE

THE PROTECTORS.

Maintenance

Model DH80 should be inspected and the sprinkler main-

tained in accordance with NFPA 25. Do not clean sprinklers

with soap and water, ammonia or any other cleaning fluids.

Remove dust by using a soft brush or gentle vacuuming. Re-

move any sprinkler/cover assembly, which has been painted

(other than factory applied) or damaged in any way. A stock

of spare sprinklers should be maintained to allow quick re-

placement of damaged or operated sprinklers. Prior to in-

stallation, sprinklers should be maintained in their original

cartons and packaging until used to minimize the potential

for damage to sprinklers that would cause improper opera-

tion or non-operation.
