Tyco AquaMist AM4 Bedienungsanleitung

General

Description

The Tyco®Type AM4 AquaMist Noz-

zles are stainless steel, open (non-

automatic) nozzles intended for use

with total compartment, engineered,

water mist deluge systems. They are

intermediate pressure nozzles which

utilize a single fluid jet impinging on a

diffuser to produce a spray having a

range of water droplet sizes suitable

for the extinguishment of Class B fires,

as well as incidental Class A fires.

Itisrecommendedthattheenduserbe

consulted with respect tothe suitability

of the materials of construction and

finish for any given corrosive environ-

ment. The effects of ambient tempera-

ture, concentration of chemicals, and

gas/chemical velocity, should be con-

sidered, at a minimum, along with the

corrosive nature to which the nozzles

may be exposed.

NOTICE

The Type AM4 AquaMist Nozzles de-

scribed herein must be installed and

maintained in compliance with this

document and with the applicable

standards of the National Fire Protec-

tion Association, in addition to the

standards ofany other authorities hav-

ing jurisdiction. Failure to do so may

impair the performance of these de-

vices.

Thedesignofindividualwatermistsys-

tems can vary considerably, depend-

ingonthecharacteristics andnatureof

the hazard and the basic purpose of

the watermist system. Because of

these variations, the design of water

watermist systems for fire protection

must only be performed by experi-

enced designers who thoroughly un-

derstand the limitations as well as ca-

pabilities of such systems.

The owner is responsible for maintain-

ing their fire protection system and de-

vices in proper operating condition.

The installing contractor or sprinkler

manufacturer should be contacted

with any questions.

IMPORTANT

Always refer to Technical Data

Sheet TFP700 for the “INSTALLER

WARNING” that provides cautions

with respect to handling and instal-

lation of sprinkler systems and com-

ponents. Improper handling and in-

stallation can permanently damage

a sprinkler system or its compo-

nents and cause the nozzle to fail to

operate in a fire situation or cause it

to operate prematurely.

Installation

NOTICE

A 1/2 inch NPT nozzle joint should be

obtained with a minimum to maximum

torque of 7 to 14 ft.lbs. (9,5 to 19,0

Nm). Higher levels of torque may dis-

tort the nozzle inlet and cause leakage

or impairment of the nozzle.

The Type AM4 AquaMist Nozzles

must be installed in accordance with

the following instructions.

Step 1. The AM4 is to be installed in

the pendent position as shown in Fig-

ure 1.

Step 2. With pipe thread sealant ap-

plied to the pipe threads, hand tighten

the nozzle into the nozzle fitting.

Step 3. Tighten the nozzle into the

nozzle fitting using only the W-Type 6

Wrench(Ref.Figure2).Withreference

toFigure1,theW-Type6Wrenchisto

be applied to the wrenching area.

Care and

Maintenance

The Tyco®Type AM4

AquaMist

Noz-

zles must be maintained and serviced

in accordance with the following in-

structions:

NOTICE

Before closing a fire protection system

main control valve for maintenance

work on the fire protection system that

itcontrols,permissiontoshutdownthe

affectedfireprotectionsystemmustbe

obtained from the proper authorities

and all personnel who may be affected

by this action must be notified.

Type AM4

AquaMist

Nozzles must

never be painted, plated, coated or

altered in any way after leaving the

factory; otherwise, the spray perform-

ance may be impaired.

Care must be exercised to avoid dam-

agetothenozzles-before,during,and

after installation. Nozzles damaged by

dropping, striking, wrench twist/slip-

page, or the like, must be replaced.

Frequent visual inspections are rec-

ommendedtobeinitiallyperformedfor

nozzles installed in potentially corro-

sive atmospheres to verify theintegrity

of the materials of construction and

finish as they may be affected by the

corrosive conditions present for a

given installation. Thereafter, annual

inspections per NFPA 25 are required.

The owner is responsible for the in-

spection, testing, and maintenance of

their fire protection system and de-

vices in compliance with this docu-

ment, as well as with the applicable

standards of the National Fire Protec-

tion Association (e.g., NFPA 25), in

addition to the standards of any other

authorities having jurisdiction. The in-

stalling contractor or sprinkler manu-

facturer should be contacted relative

to any questions.

Water spray fixed systems should be

inspected, tested, and maintained by a

qualified Inspection Service in accord-

ance with local requirements and/or

national codes.
