Ultra Low Flow AQUAMIST Nozzles
Type ULF AM27
Automatic (Closed)
General
Description
The TYCO Ultra Low Flow AQUAMIST
Nozzles Type ULF AM27 are closed (au-
tomatic) 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 con-
trol of Class A fires.
It is recommended that the end user
be consulted with respect to the suit-
ability of the materials of construction
and finish for any given corrosive envi-
ronment. The effects of ambient tem-
perature, concentration of chemicals,
and gas/chemical velocity should be
considered, at a minimum, along with
the corrosive nature to which the nozzles
may be exposed.
NOTICE
The Type ULF AM27 AQUAMIST Nozzles
de scribed herein must be installed and
maintained in compliance with this docu-
ment and with the applicable standards
of the National Fire Protection Associa-
tion, in addition to the standards of any
authorities having jurisdiction. Failure to
do so may impair the performance of
these devices.
The design of individual water mist sys-
tems can vary considerably, depend-
ing on the characteristics and nature
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
Installation can permanently dam-
age 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.

of the hazard and the basic purpose
of the water mist system. Because of
these variations, the design of water
mist systems for fire protection must
only be performed by experienced
designers who thoroughly understand
the limitations as well as capabilities of
such systems.
The owner is responsible for maintaining
their fire protection system and devices
in proper operating condition. The install-
ing contractor or nozzle manufacturer
should be contacted with any questions.
