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.

Description
TYCO Ultra Low Flow AQUAMIST
Nozzles Type ULF AM29 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 and the
protection of data centers�
It is recommended that the end user be
consulted with respect to the suitabil-
ity 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 ULF AM29 AQUAMIST
Nozzles de scribed herein must be
installed and maintained in compliance
with this document and with the appli-
cable standards of the NATIONAL FIRE
PROTECTION ASSOCIATION (NFPA),
in addition to the standards of any
