2.2 HARNESS
Contour is available with a flame-
retardant polyamide/ polyester or a
TM
Kevlar
/NomexTM harness (identified by
a -K in the unit part number). Buckles are
of black nylon or stainless steel. Pressstuds are of brass or nickel plated brass.
On Kevlar
TM
versions the pneumatics and
hoses are attached to the harness by
loops closed by press-studs. On EN
versions the loops do not open.
For wearer comfort, a lumbar pad (fitted
as standard), or a full back pad (fitted as
an option) is provided. Both are fabricated
from flame-retardant material and packed
with flame retardant, closed cell foam.
The lumbar pad is held in place by four
press-studs. The full length pad is held by
press studs and the harness straps.
A chest-strap is available as an option.
2.3 CYLINDER BAND
Contour can be configured for use with
one or two (Duo), 200, 207 or 300 bar,
steel or fully wrapped aluminium carbon
fibre composite cylinders (see Table 3).
Cylinders are secured to the light-weight
back-plate by a webbing cylinder band
and a cylinder valve retainer (CVR). A
conversion kit is available for converting
single cylinder apparatus to Duo.
The webbing cylinder band is closed by a
cam lock buckle with a latch that prevents
accidental opening. The band can be
adjusted to accept the range of cylinders
listed in Table 3. The cam-lock buckle
facilitates replacement of similar size
cylinders without cylinder band
adjustment.
Contour Duo cylinder bands can be
easily altered by the wearer (no tools
required) to mount a single cylinder,
centrally on the back-plate.

CONTOUR
2.4 THE PNEUMATIC
SYSTEM
The pneumatic system has two pressure
reduction stages: air from the cylinder is
reduced to a medium-pressure (MP) of
between 5.5 and 11 bar by the reducer.
The second pressure reduction is
performed in the facemask Demand
Valve (DV).
Air from the cylinder passes through a
sintered bronze particle filter in the
cylinder connector, which protects the
pneumatic system, then through a short
length of High Pressure (HP) braided
hose to the reducer inlet manifold.
2.5 REDUCER
The reducer is a simple, self-regulating,
spring and piston device, which requires
no adjustment. It has a pressure relief
valve (PRV) that protects the MP system
from over-pressurisation.
On versions fitted with the IRIS data-
communications system, the warning
whistle and pressure gauge are
incorporated within the IRIS unit.
The warning whistle sounds when
pressure in the cylinder falls to 55 bar (±5
bar).
The duration of the air remaining in the
cylinder, from the start of the warning
whistle, is listed for each cylinder type
under Warning Period in Table 3.
The pressure gauge dial is photo
luminescent to aid use in low light levels.
The lens is impact resistant
polycarbonate. A rubber shroud protects
the gauge.
Should the gauge, whistle or hose
become damaged, a restrictor in the
reducer limits air-loss to less than 25
litres per minute.
2.7 DEMAND VALVE
The DV operates in conjunction with the
facemask spring-loaded exhale valve to
maintain a positive pressure within the
facemask.
The DV has a servo-assisted tilting
diaphragm mechanism that responds to
pressure changes within the facemask to
regulate the flow of air to the mask,
ensuring that pressure within the mask
remains safely above ambient.
Air from the reducer is connected through
a reinforced chlorinated polyethylene
hose to the facemask-mounted DV, which
regulates the air supplied to the wearer.
2.6 GAUGE AND WHISTLE
A high-pressure hose from the reducer
inlet manifold connects air, at cylinder
pressure, to a warning whistle and
pressure gauge mounted on the Contour
shoulder strap.
On standard versions, the warning whistle
and pressure gauge are mounted on the
left-hand shoulder strap.
The DV has a reset button that enables
wearers to close the air-flow through the
DV, allowing the facemask to be removed
during test procedures and at the end of a
task without loss of cylinder air.
6
CONTOUR
When the apparatus is donned the DV is
normally “reset” (closed), and is opened
(activated) when the wearer takes a first
breath.
The DV has a supplementary flow device
(bypass), that the wearer can open using
the bypass knob.
When the bypass is used the unregulated
flow of air through the DV reduces
cylinder duration.
The DV is connected to the facemask by
a Quick-Fit (QF) bayonet fitting with a
spring-loaded locking catch to prevent
accidental disconnection.
2.8 OPTIONAL
ATTACHMENTS
The options available are:
• Decontamination attachment (DCC)
- facilitates airline connection into a
gas-tight chemical suit, permitting
the wearer to breathe from an
airline during extended
decontamination procedures.
• Rescue mask attachment (RSM) -
permits the wearer to supply a
rescue mask or an air powered
resuscitator from own cylinder air.
This reduces the duration of the
cylinder supply.
• Airline attachment (AL) - permits
Contour to be used with an airline.
The cylinder provides emergency
backup.
Note:
Air for use with airlines must conform to
Breathable Air as detailed in Section 1.
PanaSeal is suitable for medium and
smaller face sizes; PanaVisor is suitable
for medium to larger face sizes. Vision 3
is available in three sizes: small, medium
and medium/large which cover most face
sizes. Promask PP is available in two
sizes: small/medium and medium/large.
Vision 3 is moulded in grey silicone,
while PanaSeal and PanaVisor are of
non-dermatitic, black neoprene or blue
silicone. Promask PP is moulded in
hypo-allergenic, black Procomp
soft silicone inner mask.
The polycarbonate visors conform to EN
166 Grade B for medium impactresistance and AS/NZS 1337 : 1992 for
high-impact resistance.
Versions of the above masks are also
available with helmet attachment clamps
fitted. Please contact Customer Services
for further information.

MONTHLY CHECKS
3.1 CHECK APPARATUS
Contour must be clean and in good
condition. Check that all hose retaining
press-studs (if fitted) are closed. Fully
slacken the waist-belt and shoulder
straps ready for use.
3.2 REPLACING CYLINDERS
WARNING:
On Duo models, always fit matching,
fully-charged cylinders.
1. Close the cylinder valve (on Duo
Sets, close both cylinder valves).
2. Open the facemask bypass to vent
the system.
3. Undo the cylinder connector(s).
8
CONTOUR
4. Grasp and pull the edges of the
cam-lock buckle with index finger and
thumb of the left hand and use the right
index finger to slide the ribbed, release
catch. Pull the cam-lock fully open.
5. Open the buckle and remove the
cylinder(s).
6. Place fully charged cylinder(s) on
the back-plate with the cylinder outlet(s)
through the cylinder valve retainer(s).
7. On Duo, ensure that the dividing
loop is between the cylinders.
firmly onto the cylinder valve (onto the
Duo manifold).
Note:
In some instances it may be necessary to
adjust the size of the cylinder band. To do
this:
i) Engage the buckle hinge, but do
not close the cam-lock.
ii) Tighten the cylinder band using the
slide buckle, until the band holds the
cylinder securely.
iii) Close the cam-lock buckle.
When Contour is used with an airline
check that:
i) The airline is in good condition, free
from splits, bulges and abrasions.
ii) The airline connector is in good
condition and that it connects securely to
the Contour pigtail.
iii) The air supply conforms to EN
12021 or AS/NZS1715 : 1994 (see
Section 1.3 - Compressed Airline
Supplies).
iv) The Contour airline coupling is in
good condition.
3.3 DUO CYLINDER BAND
The Duo cylinder band can be adapted to
hold two or one cylinder.
In normal use, the dividing loop passes
between the two cylinders, to separate
and secure them. By flattening the
dividing loop against the cylinder band
wearers can configure Duo for single
cylinder operation.
To alter the Duo cylinder band to hold
only one cylinder:
1. Slide the dividing loop so that it is
next to the back-plate and lying flat on the
cylinder band.
8. Check that the cylinder hand-wheel
connector O-ring(s) is (are) clean and in
good condition and screw the connector
