Ultra Low Flow AQUAMIST
Type ULF AM28 Nozzles
Automatic (Closed)
General
Description
TYCO Ultra Low Flow AQUAMIST Type
ULF AM28 Nozzles are closed (auto-
matic) 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 temperature,
concentration of chemicals, and gas/
chemical velocity should be consid-
ered, at a minimum, along with the cor-
rosive nature to which the nozzles may
be exposed.
NOTICE
The TYCO Ultra Low Flow AQUAMIST
Type ULF AM28 Nozzles described
herein must be installed and maintained
in compliance with this document and
with the applicable standards of the
VdS CEA 4001 "Sprinkler Systems
Planning and Installation" or EN12845
"Automatic Sprinkler Systems - Design,
Installation and Maintenance", in addi-
tion to the standards of any authorities
having jurisdiction. Failure to do so
may impair the performance of these
devices.
IMPORTANT
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.

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
The TYCO Type ULF AM28 AQUAMIST
Nozzles are VdS approved when used
as part of an engineered, wet-pipe
water mist system. In particular, the
VdS approval was performed in accor-
dance with test protocols "Fire tests
for 'Office, OH1' and similar" dated
December 6, 2007, and "Fire tests for
'Hotel, OH1' and similar" dated October
10, 2011.
