Panther/Cougar/Puma SCBA Operation Manual
dition to the audible alarm located on the rst stage reg-
ulator. On a 2216 psig SCBA, the ¼ LED will turn red
and begin to ash between 510 and 598 psig; on a 3000
psig SCBA, the ¼ LED will turn red and begin to ash
between 690 and 810 psig; on a 4500 psig SCBA, the ¼
LED will turn red and begin to ash between 1035 and
1215 psig. When the pressure drops to 10% of cylinder
capacity, the red LED begins to ash noticeably faster
and continues ashing in this manner until air pressure
drops below approximately 200 psig, at which time the
display will turn off. No lighted LEDs represents zero air
pressure.
An external red LED, mounted on the front of the HUD
module, warns others of the user’s low air status by
ashing at the same time the ¼ LED is ashing inside
the HUD module. The external red LED ashes notice-
ably faster when the pressure drops to 10% of cylinder
capacity.
A photodiode is mounted externally on the top of the
HUD module. It senses ambient light conditions and
adjusts the intensity of the green HUD LEDs to match
these conditions. If the ambient light is bright, the LEDs
are in bright mode. In no-light or low-light conditions,
the LEDs are in dim mode so that they are not distract-
ing to the user.
The transducer module on the backpack has a red LED
that acts as a battery status indicator. When the SCBA is
in storage (the cylinder valve is not opened), the amber
LED will ash once every 10 seconds to indicate a us-
able battery condition. The amber LED ashes every two
seconds to indicate a low battery condition, and it will
cease ashing altogether to indicate a dead battery.
WARNING
A Duracell Ultra 123 or Eveready En-•
ergizer EL 123A PBP must be used in
the HUD transducer module in order to
maintain the intrinsic safety certica-
tion of this product.
Failure to comply with this Warning •
may lead to personal injury, illness, or
death.
To replace the battery, remove the slotted battery cap
located on the top of the transducer module (located on
the side of the cylinder band) using a coin or a large,
at-blade screwdriver. Remove the old battery, install a
new battery in the orientation shown on the side of the
case, and replace the battery cap.
WARNING
If the low battery alert activates (am-•
ber LED on the backpack-mounted
transducer module ashes every two
seconds) during storage, or if the am-
ber LED on the backpack-mounted
transducer module does not ash at all
during storage, the battery must be re-
placed before using the SCBA.
If the low battery alert in the HUD ac-•
tivates during actual use (amber LED
at the lower right of the display ashes
once every second), the SCBA may
continue to be used. The battery must
be replaced before the next usage.
Failure to comply with this Warning •
may lead to personal injury, illness, or
death.
D. Chest-mounted Gauge
(Optional for Panther SCBA, and Optional for Cougar
SCBA if a HUD Is Installed)
The chest-mounted pressure gauge is mounted on the
right shoulder strap and may be swiveled 360° for easy
viewing. When the cylinder valve is opened, the gauge
indicates the air pressure remaining in the cylinder.
E. Second Stage Regulator
WARNING
An impact to the second stage regula-
tor when the cylinder valve is open may
inadvertently activate the First-Breath-
On mechanism, causing air to ow from
the regulator and diminishing the air in
the cylinder. Failure to comply with this
Warning may lead to personal injury, ill-
ness, or death.
The pressure-demand second stage regulator is
mounted on the facepiece by the SPERIAN AIR KLIC
™
system. The mechanism automatically locks in place
when the regulator is pushed into the AIR KLIC, and
is detached when the release buttons are pressed. To
prevent inadvertent air ow, the regulator will not oper-
ate until the First-Breath-On mechanism is activated or
the manual override button on the front of the regulator
is pressed. The ow of air can be stopped by pressing
the shutoff button. A large red knob on the right side of
the regulator controls an adjustable bypass valve. Turn-
ing this knob counterclockwise provides a constant ow
of air.
