-6 month stale air date (sticker with month and year of when to change)

Question 9

What is the back frame made from?

Answer 9

ionized aluminum and high temp plastic with articulating kevlar straps rated for 1000lb beaking force with a drag strap

Question 10

How many sensors are on the back of the pack, and what are the colours associated when working?

Answer 10

2 Pak-Alert sensors
Green- in use
Amber - Low air (33%-50%) low battery
Red- PASS alarm activation/ full alarm
Emits radio frequency to communicate with PakTraker

Question 11

What sounds are emitted from harness?

Answer 11

Chirping: pass activation and or low battery
Crescendo Alarm: full activation of pass alarm

Question 12

When does the PASS activation start, and when does the full alarm start?

Answer 12

Activation: 20 seconds of no movement
Full Alarm: 12 seconds after activation
Total: 32 seconds

Question 13

What does the tags on the harness indicate?

Answer 13

1: indicates the apparatus it belongs to
2: When the harness needs to be flow tested

Question 15

How does air go from the bottle to the face piece?

Answer 15

Dual Redundant Pressure Reducer which has 6 components:
1. High pressure inlet
2. Primary reducer (feed) 5500 to 85-110psi
3. Secondary reducer (feed) 5500 to 145 - 170psi
4. Low Cylinder transfer valve
5. Automatic transfer valve
6. Relief Valve

Both reducers are connected by the automatic transfer valve

Reduction in the primary feed line automatically causes the system to move to secondary line activating the Vibralert (also switches at 33% air)

Question 16

How does the hand held console get power/ gauge readings from the pak?

Answer 16

Through the transducer which takes power to the console and the pressure from the bottle through two lines.

Question 17

At what PSI does the vibralert activate at?

Answer 17

1815

Question 18

At what PSI does the RIC UAC relief valve activate at?

Answer 18

5500psi

Question 19

What does the SEMSII console have on it?

Answer 19

Large sweep gauge indicating the pressure in the cylinder (must be within 10% of the pressure from the cylinder sweep gauge)

3 buttons:
1. Red - PASS activation
2. Yellow - reset, acknowledge, turn off
3. Grey - ID login, and withdrawal from structure acknowledgment

Lights around red pass alarm:
1. Green flashing: 34% - 100% air, normal operations
2. Pass alarm activation or <34%: alternating red lights

Buddy system HUD under sweep gauge:
1. Green light = 100-50% air
2. Yellow = 34-49% air
3. Red <34%

ID lights:
1. Red evacuation light (running person logo)
2. Green ID light (shows “ID”)
3. Yellow range Light (triangle with radio wave symbol)
4. Red Pass alarm (triangle with “!” in the middle)

Question 20

What does the regulator deliver PSI at?

Answer 20

Inhaling - 0.8 to 1.5 PSI
Exhaling - 1.5 to 3.0 psi

Question 21

What PSI and LPM does the purge valve deliver?

Answer 21

15.7 PSI
125 to 225 lpm of flow

Question 22

What is the button on the regulator called, and what is its intended purpose?

Answer 22

Air saver switch
Saves air so there is no free flowing air when regulator is not in use, but cylinder has charged the system

Question 23

What is the spray bar?

Answer 23

it releases air into the face mask

Question 24

What are the lights on the HUD on the regulator?

Answer 24

2 green lights: 100-76% air
1 green light: 51-75% air
1 amber light: 34-50% air
1 red light flashing: <34%
1 red light on right hand side indicates low battery

Question 25

What is the max working pressure of the regulator?

Answer 25

300PSI

Question 26

When does the vibralert activate?

Answer 26

When the secondary system in the Dual Redudant Bypass system has been activated at 135PSI

Question 27

What is the face mask made of?

Answer 27

High temperature polycarbonate

Question 28

What temp can the face mask withstand?

Answer 28

it meets the NFPA required 500f for 5mins, then 1800f for 10 seconds then a 6” drop test. Must maintain integrity, visibility through mask is not a requirement

Question 29

What does the headdress made of?

Answer 29

kevlar

Question 30

What other features on the face mask?
