Description; Backpack And Cylinder; First Stage Pressure Reducer - Honeywell TITAN SCBA Operation Manual

IV. DESCRIPTION
The Titan SCBA provides the wearer with respiratory
protection in hazardous environments, and may be used
for entrance into and escape from atmospheres that are
immediately dangerous to life or health (IDLH).The Titan
SCBA is an NFPA- and NIOSH CBRN-compliant SCBA,
and may be used for fi refi ghting and/or CBRN incident
response. It may be used as a supplied air respirator (in
non-CBRN applications only) or self-contained breathing
apparatus.
WARNING
Not all components
approved for use on the Panther and Warrior
SCBAs are approved for use on the Titan
SCBA. You must check the NIOSH approval
label in this manual for components and
accessories approved for use on the Titan
SCBA. See the Table of Contents. Failure
to comply with this warning may lead to
personal injury, illness, or death.
The Titan SCBA meets all requirements of the NFPA 1981
Standard, 2013 Edition, Open-Circuit Self-Contained
Breathing Apparatus for Emergency Services.
See NFPA 1500, Standard on Fire Department Occupa-
tional Safety and Health Program, for proper use of SCBAs
in the work environment.
The Titan SCBA meets the requirements of the NIOSH
CBRN standard and has been granted NIOSH CBRN ap-
proval. The NIOSH CBRN approval label is located on the
right side of the pressure transducer cover on the back-
pack frame.
A. Backpack and Cylinder
1. The backpack consists of a lightweight aluminum
backplate with an aluminum hip plate that both swivels
and hinges on the backplate. The backpack has an
integrated carrying handle and an attached webbing
strap handle. The cylinder is attached by a stainless
steel band with integrated adjustment mechanism, and
has a release latch on the right side (when looking at
the cylinder with the valve pointing down). The Titan
harness is made of Kevlar straps. The pressure gauge,
mounted on the right shoulder strap, is integrated
with the PASS device on units equipped with a PASS,
and is a standard chest-mounted gauge on units not
equipped with a PASS. The gauge indicates the cylin-
der pressure once the cylinder valve has been opened.
The intermediate pressure hose is routed over the left
shoulder, and includes an optional electrical/pneumatic
quick connector in line, which allows for easy removal
of the second stage regulator. Connection of the
quick-connect automatically connects the electronics
required for the Heads-Up Display (HUD).
2. The air cylinder is of composite construction with
an aluminum inner liner overwrapped by carbon fi ber,
and has a maximum working pressure of 4500 psig
(high pressure) in 30-, 45-, and 60-minute durations;

or 2216 psig (low pressure) in 30-minute duration. An
all-aluminum cylinder and fi berglass composite hoop-
wrapped cylinder with a maximum working pressure of
2216 psig (low pressure) in 30-minute duration are also
available.
DO NOT pick up or carry a cylinder by
the handwheel. Use the cylinder valve
handwheel ONLY to open or close the valve.
Do not drop a cylinder on the handwheel, or
bump the handwheel. This may cause the
cylinder valve to open inadvertently and the
cylinder to become airborne under the thrust
of air released from the open valve, causing
injury or death. ALWAYS pick up and carry
an air cylinder by the cylinder body. Failure
to comply with this warning may lead to
personal injury, illness, or death.
B. first Stage Pressure Reducer
1. The fi rst stage pressure reducer contains:
• Pressure reduction components.
• Primary low air alarm activation and adjustment
mechanisms.
• Intermediate pressure connections to the second
stage regulator, audible alarm, and buddy breath-
er (EBSS), if so equipped.
• High pressure connections to the HUD transducer,
remote pressure gauge, the universal air connec-
tion, and the audible alarm.
2. The fi rst stage pressure reducer lowers cylinder
air pressure to a nominal 115 psig. The relief valve
activates to protect the system when the intermediate
pressure exceeds 200 to 225 psig.
3. The fi rst stage pressure reducer is connected to a
warbling whistle or a bell alarm. The alarm is located
on the fi rst stage pressure reducer body, protected by
a metal cover. The low pressure SCBA audible alarm
activates at 731 to 820 psig (2216 psig system); the
high pressure SCBA audible alarm activates at 1485 to
1665 psig (4500 psig systems). The audible alarm will
continue to sound until the air pressure drops below
200 psig.
• You must use a CBRN facepiece when
using this SCBA in a potential or known
CBRN contaminated atmosphere. Use of a
facepiece other than a CBRN facepiece will
void NIOSH CBRN certifi cation and NFPA
compliance certifi cation.
• If the low battery alert activates (amber
LEDs on the front and back PASS fl ashing
every ten seconds) during storage, the
batteries must be replaced before using the
SCBA.
• Activation of the visual low air alarm
(fl ashing red LED) in the HUD may or may
not coincide with the audible alarm (whistle,
warbling whistle, or bell) on the SCBA. As
soon as the fi rst alarm activates, PROCEED
IMMEDIATELY TO A SAFE AREA.
