Honeywell Titan SCBA, 2013 2
WARNING —Continued
• You must have binocular vision (vision from
both eyes) to see and interpret th e display
correctly. Your visual acuity while wearing
the facepiece must meet the requirements
set forth by the authority having jurisdiction
over your operation and/or workplace.
• Failure to comply with this warning may
lead to personal injury, illness, or death.
C. Heads-up Display (HUD)
NOTE
The Titan SCBA comes equipped with a Heads-
Up Display (HUD).
1. The HUD is mounted on the second stage regula-
tor. When the second stage regulator is installed in the
Twenty/20+ facepiece, the display can be seen through
openings in the facepiece nozzle cover. When the
cylinder valve is opened, the HUD activates automati-
cally, and indicates the air pressure remaining in the
cylinder. The display consists of four green LEDs,
representing Full, 3⁄4, 1⁄2, and 1⁄3. At full cylinder pres-
sure, all four LEDs are illuminated. As the air pressure
in the cylinder decreases, the LEDs turn off one at a
time, thereby indicating the air pressure status. When
the pressure drops below 50% of cylinder capacity, the
LED representing 1⁄2 cylinder capacity starts to fl ash,
and continues to fl ash for a short time (approximately
20 seconds) before returning to being continuously lit.
When the pressure drops to 1⁄3 (33%) of cylinder ca-
pacity, the last green LED turns red and begins to fl ash,
giving the user a visual low pressure alarm in addition
to the audible alarm located at the upper left of the
backpack. On a 2216 psig SCBA, the 1/3 LED will turn
red and begin to fl ash between 731 and 820 psig; on a
4500 psig SCBA, the 1/3 LED will turn red and begin to
fl ash between 1485 and 1665 psig. When the pressure
drops to 10% of cylinder capacity, the red LED begins
fl ashing noticeably faster and continues until air pres-
sure drops below approximately 200 psig, at which time
the display will turn off. There are no LEDs represent-
ing zero air pressure.
2. An external red LED, mounted on the front of the
HUD module, warns others of the user’s low air status
by fl ashing at the same time the 1⁄3 LED is fl ashing
inside the HUD module. The external red LED fl ashes
noticeably faster when the pressure drops to 10% of
the cylinder capacity. A red LED at the lower right of the
backpack performs the same functions.
3. The back PASS has an amber LED battery status
indicator. In storage or when the SCBA is activated
manually or by pressure from the cylinder, the amber
LED fl ashes every ten seconds to indicate a low battery
condition, and will cease fl ashing altogether to indicate
a dead battery. An audible beep will also sound every
ten seconds to indicate a low battery condition.
WARNING
The following alkaline battery types must be
used in the battery compartment in order to
maintain the intrinsic safety certifi cation of
this product:
• Duracell MN1400
• Duracell PC1400
• Energizer E93
• Energizer EN93
4. To replace the batteries, remove the slotted battery
cap located on the lower right hand side (when look-
ing at the cylinder with the valve pointing down) of the
backpack, using a coin, a large, fl at blade screwdriver,
or the male end of the waist strap buckle. Remove the
old batteries and install new batteries in the orientation
shown on the molded battery cover. Replace the bat-
tery cap hand tight.
NOTE
Refer to applicable local ordinances for
appropriate disposal of used batteries.
WARNING
• Prior to re-installing the battery cap,
ensure that the cap O-ring is not damaged.
Replace damaged O-rings as required. After
installation, ensure that the cap O-ring is not
exposed or pinched in the seal area. Failure
to comply with this warning may lead to
personal injury, illness, or death.
• If the low battery alert activates (amber LED
on the back PASS fl ashes every 10 seconds,
along with an audible beep) during storage,
the batteries must be replaced before using
the SCBA.
• If the battery alert in the HUD activates
during actual use (amber LED at the lower
right of the display fl ashes once every
second), the SCBA may continue to be used.
The batteries 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
If the SCBA is not equipped with a PASS device, the
chest-mounted pressure gauge is mounted on the right
shoulder strap and may be swivelled 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 regulator
when the cylinder valve is open may
inadvertently activate the First-Breath-On
mechanism, causing air to fl ow from the
regulator and diminishing the air in the
cylinder.
