1 TECHNICAL DESCRIPTION
The S9 and S9 Incurve is a compressed air breathing apparatus for work in a
contaminated environment. The apparatus consists of:
• A harness assembly
• An air supply cylinder
• A face mask with breathing valve and by-pass including:
-A wireless Heads-Up Display (HUD) inside the face mask
• A regulator unit including:
-A Breathing apparatus computer (BAC)
-A Digital Display Unit (DDU)
-A Rapid Intervention Crew/Company Universal Air Connection System (RIC UAC)
-An integrated Personal Alert Safety System (PASS)
-Optional tracking senders
-Optional telemetry unit
• An extra air/rescue hose connection
The S9 and S9 Incurve self contained breathing apparatus (SCBA) uses clean dry air
compressed in a cylinder, carried on the back. The air is fed to a pressure regulator
which reduces the cylinder air pressure to a secondary pressure of approximately 110
psi. The air is then supplied to the face piece through the mask mounted breathing
valve.
The breathing valve is of the pressure-demand type that releases air on inhalation.
The S9 and S9 Incurve operates with positive pressure which keeps toxic gases from
leaking into the facepiece. Even if leakage was to occur, the positive pressure keeps
surrounding air out of the mask, although under such conditions duration of the air
supply may decrease.
A primary audible low air warning device placed at the pressure gauge / DDU is
located at the left shoulder in front of the user. A wireless Heads-Up Display (HUD)
installed inside the face mask acts as a visual pressure gauge and also provides a
secondary visual low air warning at both 1/2 and 1/3 cylinder pressure. The HUD
allows both the cylinder pressure and the visual low air warning to always be in the
wearer’s eld of vision. The HUD also includes a low battery indicator.
The apparatus is equipped with a Personal Alert Safety System (PASS) which is an
integrated PASS unit designed to meet the NFPA 1982 Standard on PASS for Fire
Fighters 2018 Edition. The PASS unit is integrated into the SCBA and is automatically
activated by air pressure from the SCBA. Tracking system and telemetry system can be
installed as an option.
1.1 HARNESS ASSEMBLY
The S9 incorporates a unique double pivoting padded harness assembly. The heavily
padded harness includes a rescue/carrying handle. Chest strap and a buddy
breathing hose pouch are optional features.
The harness can be adjusted for different body sizes by changing the distance
between the hip belt and the shoulder harness. The height adjustment can be made
with cylinder mounted on the SCBA.

9
1.2 INCURVE HARNESS
An alternate S9 Incurve harness is also available. The S9 Incurve harness is the same
as the padded harness with the pneumatics mounted on the same backframe. The
difference being the Incurve harness includes a minimum of textile parts making the
Incurve harness easy to clean, robust and light weight - without compromising comfort.
1.3 AIR SUPPLY
The compressed air supply utilize lightweight aluminum/composite cylinders wrapped
in berglass, kevlar glass or carbon ber available in 30, 45 and 60 minute
duration*.
The cylinders are tted with a valve which includes a built-in pressure gauge. The
cylinder valve is equipped also with a burst disc, designed to rupture and let air out if
the cylinder should be inadvertently overcharged.
CAUTION! SHOULD THE CYLINDER BE EXPOSED TO A PRESSURE THAT CAUSES THE BURST DISC TO RUPTURE, IT
MUST BE RETURNED TO AN AUTHORIZED SPIROMATIC S SERVICE CENTER FOR INSPECTION AND REPAIR.

WELL AS ON ENVIRONMENTAL PRESSURE AND WHETHER THE CYLINDER WAS FULLY CHARGED AND WHETHER
THE FACEPIECE FITS. DURATION CAN VARY 50 % OR MORE.

10
1.3 FACE MASK
The outer and inner masks are made from a specially compounded rubber material to
ensure a high degree of resistance to ozone ageing and acceptability to the wearer.
The mask is equipped with a large, easily replaceable visor which is held in place
by two half frames and two screws. The S9 mask includes a visor meeting the Lens
Radiant Heat Resistance Performance and Elevated Temperature Heat and Flame
Resistance Performance requirements of NFPA 1981-2019. The S9 mask is available
with either a fabric head harness or a rubber head harness. The face piece also has
provisions for tting spectacles.
A speech diaphragm is mounted within the inner mask with a direct outlet to outside
the mask to ensure the best possible communication. In addition, an inner cone over
the speech diaphragm enhances the speech diaphragm performance. As a further
enhancement to speech reproduction an external speech cone is tted which also acts
as a positive security lock for the breathing valve.
The S9 mask is available in four sizes: SMALL, MEDIUM, LARGE, and EXTRA LARGE.
The standard size facemask is the LARGE size.
Size markings:
• The SMALL mask is marked “S” on the outer mask and “M” on the inner mask.
• The MEDIUM mask is marked “M/L” on the outer mask and “M” on the inner mask.
• The LARGE mask is marked “M/L” on the outer mask and “L” on the inner mask.
• The EXTRA LARGE mask is marked “XL” on the outer mask and “L” on the inner
mask.
Size marking on outer mask Size marking on inner mask
AMBIENT AIR HATCH MASK
Positive pressure is activated by closing the ambient air hatch by pushing the
exhalation valve cover against the face mask. To shut off positive pressure and
breathe ambient air, simultaneously press down the indicator arm and push the
exhalation valve cover away from the face mask.
Activated positive pressure Ambient air mode

11
FIRST BREATH MASK
Positive pressure is automatically activated by the rst breath and can be switched off
manually by pushing the lifting arm on the breathing valve away from the diaphragm
cover.
Activated positive pressure Positive pressure switched off
1.4 BREATHING VALVE AND BY-PASS VALVE
The SPIROMATIC S breathing valve has a “plug-in” connection to connect it to the
face mask. The outer speech cone locks the breathing valve into position. This feature
provides a safe positive connection between the face mask and breathing valve and
prevents accidental disconnection.
The by-pass valve overrides the normal automatic function of the pressure demand
valve. When the by-pass valve is opened the air will free ow into the mask. To open
the valve turn the red knob counter clockwise. To close the valve turn the red knob
fully clockwise.
NOTE! WHEN THE BY-PASS VALVE IS OPEN THE DURATION TIME WILL BE SHORTER. WHEN THE BY-PASS VALVE IS
OPERATED THE WEARER SHOULD ABORT ANY OPERATION AND RETURN TO AN AREA OF RESPIRABLE AIR.
1.5 REGULATOR ASSEMBLY WITH RIC UAC
The pressure regulator used in the S9 and S9 Incurve models is a balanced piston
pressure reducer with an extremely high ow capacity. The very high capacity ensures
that the positive pressure is maintained in the mask even at low cylinder pressures and
at extremely high breathing rates.
The regulator unit is of a “plug in” type which means that it is pushed into a manifold
and locked in place with a locking clip and cover. This modular system enables
simple servicing to be carried out with minimum down time for the apparatus by using
service exchange of modular components.

12
The manifold assembly is comprised of a regulator manifold with a handwheel
connector for the cylinder valve, a particle lter, and a high pressure Rapid
Intervention Crew/Company Universal Air Connection System (RIC UAC).
The RIC UAC will permit replenishing the breathing air cylinder of an SCBA user to be
replenished from an independent rescue breathing air supply source while the SCBA
victim remains trapped or unable to be removed from the hazardous atmosphere.
The S9 is equipped with a supplied air connector that is conveniently placed on the
right shoulder. This makes connection of air line hoses and accessories easy for the
user.

The BAC is a computer unit and pressure sensor mounted in the backplate. It is
powered by 6 AA batteries.
The wireless HUD is a combination pressure gauge and electronic low air warning
device. It also indicates PASS Pre-Alert mode and PASS Alarm mode. The HUD is
installed in the face mask.
The BAC and HUD will link together based on an address code received from each
other. The BAC and HUD to be used together must linked before use, following the
procedure in section 2.7. When the BAC is started it will only connect to the HUD it
previously has been linked to.
The HUD includes a light sensor to measure the ambient light. The brightness of the
LEDs is automatically adjusted according to the ambient light conditions. The pressure
indication displayed in the HUD is refreshed every 2 seconds. The HUD is powered
with 2 AAA batteries.
The DDU is located on the left shoulder with the mechanical pressure gauge and
mechanical whistle. The DDU is connected with a cable to the BAC. It is powered
from the BAC and has no batteries.
The motion sensor for the integrated PASS and the sensor for measuring absorbed
temperature are both located in the display unit.
The BAC, HUD and DDU activates when the SCBA cylinder valve is opened.
1.7 AUDIBLE AND VISUAL LOW AIR WARNINGS
The S9 and S9 Incurve is equipped with dual redundant low air warning End of
Service Time (EOST) indicators.
The primary low air alarm (EOST) is an audible mechanical whistle. The secondary
alarms (EOST) indicators are visual ashing yellow and red LED’s on the HUD.
Audible Warning and Pressure Gauge
When the primary air supply pressure has dropped to approximately 33 % the
audible alarm will start to sound. An analog pressure gauge is located along with
the audible mechanical whistle on the left shoulder in front of the user. An optional
secondary audible electronic low air warning is available. The sounders for the
electronic low air alarm, when activated, are located on both sides of the BAC. The
electronic low air warning also has an optional mutable function depending of the
preference of the Fire Department. If mutable, the electronic low air warning will be
silenced for 10 seconds by pressing the backlight button on the DDU (see section
3.2).
The DDU pressure gauge is a secondary pressure gauge.

14
HUD Visual Pressure Gauge and Visual Warning, BAC and DDU Visual Warning
A wireless Heads-Up Display (HUD) inside the face mask acts as a secondary visual
pressure gauge and also provides visual low air warnings at both 1/2 and 1/3
cylinder pressure. Flashing yellow and red LED’s will activate when the primary air
supply pressure has dropped to approximately 50% and the ashing red LED only at
approximately 33%. The visual ashing red LED will continue to ash until the cylinder
content is depleted and the unit is switched off.
Flashing red LEDs are also activated on the BAC and the Digital Display unit at 1/3
cylinder pressure for other reghters to see.
