Refer to Technical Data Sheet
TFP2300 for warnings pertaining to
regulatory and health information.
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
installation can permanently damage
a sprinkler system or its compo-
nents and cause the sprinkler to fail
to operate in a fire situation or cause
it to operate prematurely.

General
Description
TYCO Ultra Low Flow AQUAMIST
Type ULF AM33 Horizontal Sidewall
Nozzles are closed (automatic) nozzles
intended for use with engineered, water
mist systems. They are low-pressure
nozzles that utilize a single fluid jet
impinging on a diffuser to produce a
spray having a range of water droplet
sizes suitable for the control of Class
A fires.
It is recommended that the end-user
be consulted with respect to the suit-
ability of the materials of construction
for any given corrosive environment.
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 AQUAMIST Type ULF AM33
Nozzles described herein must be
installed and maintained in compli-
ance with this document and with the
applicable standards of the CEA 4001
“Sprinkler Systems Planning and Instal-
lation”, or EN12845 “Automatic Sprin-
kler Systems - Design, Installation and
Maintenance”, in addition to the stan-
dards of any authorities having jurisdic-
tion. Failure to do so may impair the
performance of these devices.
The design of individual water mist
systems can vary considerably,
depending on the characteristics and
nature of the hazard and the basic
purpose of the water mist system.
Because of these variations, the design
of water mist systems for fire protec-
tion must only be performed by expe-
rienced designers who thoroughly
understand the limitations as well as
capabilities of such systems.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or product manufacturer with any
questions.
Approvals
TYCO Ultra Low Flow AQUAMIST

Nozzles are intended to be used as
part of an engineered, wet-pipe water
mist system. Testing was performed in
accordance with the accommodations
portion of VdS test protocol “Protection
of Office Spaces and Accommodation
Areas with Water Mist Sidewall Sprin-
klers”, dated April, 2016.

Design
Criteria
Obtain guidance for the design of a
water mist system that utilizes the
TYCO Ultra Low Flow AQUAMIST
Type ULF AM33 Horizontal Sidewall
Nozzles from the Technical Services
department.
Installation
TYCO Ultra Low Flow AQUAMIST Type
ULF AM33 Horizontal Sidewall Nozzles
must be installed in accordance with
this section.
Do not install any bulb type nozzle if
the bulb is cracked or there is a loss
of liquid from the bulb. With the nozzle
held horizontally, a small air bubble
should be present. The diameter of
the air bubble is approximately 1,6 mm
(1/16 in.) for the 57
°
C (135
°
F) tempera-
ture rating.
A leak-tight 1/2 in. NPT nozzle joint
should be obtained by applying a min-
imum-to-maximum torque of 9,5 to
19,0 N∙m (7 to 14 ft-lb). Higher levels
of torque can distort the nozzle inlet
and cause leakage or impairment of
the nozzle.
