BA 002: PSS 7000 BA Set Flashcards
When does the electronic low pressure warning activate?
84 BAR
When does the pneumatic low pressure warning activate?
74 BAR +/-5
When the battery drops below 5.5 volts, how long is left to use the BA set?
2 hours
What is the name of the BA facemask?
The FPS (face protective system) 7000 facemask
What are the two buttons on the LDV and what do they do?
First breath button
Stops air escaping the set until the first breath is taken
Additional flow button
Provides additional air into the mask
What are the benefits of having a positive pressure inside the mask?
If a leak occurs, the pressure is released outwards instead of outside air rushing into the mask
What is the reducer and where is it mounted?
The reduce assists in the reduction of cylinder pressure to a breathable pressure (6-9 BAR). The LDV then supplies the breathable pressure to the mask
Mounted on the backplate
What is the inline connection, and what is the second person connection? What couplings do they both use?
Inline connection
Main connection from the LDV to the set
Second person connection
Used in the case of another BA wearers needing to share the same air
Both use quick release couplings (QRC)
What are the three non-kink hoses on the BA set, and where do they go?
High pressure - electronic management unit (EMU)
Medium pressure - to the LDV via the inline connection
Medium pressure - to the second person connection
