27
Q

How do you disengage the Second Stage regulator?

A

Press Shutoff button, then Air Klic buttons and remove from face piece.

28
Q

How many Liters per minute does the second stage regulator supply air

A

350 LPM

29
Q

Emergency bypass valve does what? During what kind of situations?

A
  • Turning the bypass valve knob counterclockwise provides a constant flow of breathing air.
  • Intended for emergency use only to supply breathing air should 2nd stage regulator failure occur.
  • Can also be used as a de-fogger for mask
  • Capable for supplying a maximum of
    130 liters per minute of breathing air.
30
Q

What does the manual override button on the second stage regulator do?

A

Provides the user with a burst of air, manually turns the regulator on.

Can be used to de-fog face piece.

31
Q

What does the Shutoff button on second stage regulator do?

A

Shuts off airflow to the face piece

32
Q

How many lights in the HUD and what do they mean

A

4 lights

Full- 4 green lights

¾- 3 Green lights

½- Green Light flashes for 20 seconds then both solid green

1/3- Light flashes red at rate of 500 milliseconds

10%- 1/3 light flashes at rate of 100 milliseconds

when bottle drops below 10% the red light flashes noticeably faster and continues until air
pressure drops below approximately 200 psi,
at which time the display will turn off
completely. There are no LEDs representing
zero air pressure.

33
Q

External LED Locations

A

Front of the HUD

Lower right of the backpack

(displays same lights as the HUD)

34
Q

How can you manually activate your PASS?

A

Hold the red button on the PASS for 2-3 seconds

35
Q

Chest Air Pressure Gauge increments

A

From full “F” to empty “E” using
increments of 3/4, 1/2, and 1/3.

36
Q

How can you reset a Full PASS Alarm?

A

Depress the yellow reset button twice on the side housing

37
Q

The PASS staged alarm activates after how many seconds of no movement?

A

20 seconds

38
Q

What happens if the Staged Alarm continues?

A

The alarm will increase in volume approximately every 4 seconds until full alert at 30 to 35 seconds. In full alert, the LED lights flash red and the alarm tones alternate between the front and rear mounted speakers.

39
Q

PASS is powered by what

A

4 “C”
alkaline batteries in the backpack.

40
Q

Motion reset points are located where and what is their purpose?

A

Located on the front PASS and in the rear PASS. This will reduce unwanted activations by 85%.

41
Q

Emergency Breathing Support System (EBSS) purpose?

A

Intended to supply shared EMERGENCY
AIR to a fire fighter who has become lost,
trapped, or disoriented in an IDLH
environment.

42
Q

EBSS works off of which bottle first?

A

The fuller bottle first, until both are equalized.

The SCBA with the higher dynamic intermediate pressure (70 -155 psi) will automatically supply both SCBA’s until that air is depleted.

43
Q

Location & length of EBSS hose?

A

Left side, 39 inches

44
Q

Universal Air Connection (UAC) Purpose and location

A

Located next to the
CGA handwheel for easy access. Connection
to the UAC via the mating fill coupling allows
a one direction flow of air into the user’s air
cylinder.

UAC is intended for refilling of an air
cylinder under an emergency situation.

45
Q

Facepiece name and material

A

The TITAN Twenty/20+ facepiece is made of
butyl rubber which enables it to pass the
CBRN certification test.

46
Q

Lens material / coating

A

Poly-carbonate lens, abrasion resistant coating outside, anti–fog solution inside

47
Q

What are the two ways to communicate via the Voice Amplification System (VAS)?

A

Push to talk and hands-free

48
Q

How to turn the VAS off

A

Double click power button

49
Q

Low battery indication on VAS

A

Blinking amber light

50
Q

The VAS is powered by what?

A

3 AAA batteries

51
Q

What is the purpose of the Last Chance Rescue Filter?

A

Filter provides an emergency air filter should the user become lost or trapped in a hazardous environment and deplete all air cylinder pressure.

52
Q

True/False - does the Last Chance filter cartridge generate oxygen?

A

False

53
Q

How many minutes will the cartridge provide protection?

A

15 min

54
Q

What does the Pathfinder location system do?

A

Tracks a fallen firefighter using ultrasound technology. Consists of two omni-directional transmitters (beacons) and a narrowly focused receiver (tracker). The beacons are located on the rear of the backpack on both sides.

55
Q

Who are the Pathfinder tracking systems issued to?

A

Truck Companies and USAR

56
Q

What are the colors of the Pathfinder tracking system?

A

Auxiliary beacons: yellow

Exit beacon: green

Tracker: red

57
Q

How do the lights on the PASS device operate?

A

Flashing green: Normal operation

Alternating red/green: Pre-Alarm

Flashing red: Full Alarm

58
Q

What are the SCBA shoulder straps made of?

A

AraShield material that provides a tacky surface, yet allows exceptional movement
