BA Airline system

Hi, I got some questions on the usage of Draeger Airline Breathing system.
When using the system connected to our BA set ,do we  need to turn on our own BA set ?
I've tried not to turn on my BA set. I still got the air supplied by the airline system but the problem is that the warning whistle at the pressure gauge of my own set sounded!
Next , I turn on my set. That definately shut the warning whistle. But when i checked my gauge , it shows that I'm taking air from my own bottle, not from the airline system!
I thought the airline system should feed the air whilst our own bottle is for emergency purposes? My own set could not be faulty because i've tried with other sets as well and it gave the same outcome.
Anybody working with Draeger can help?

From my recollection an airline system is exactly what it says - the normal supply is fed from a high pressure airline connected to a bank of cylinders. As a safeguard it is common practice to incorporate cylinder BA into the circuit, which may be a 10 minute escape set or a normal duration 30+ min set depending on the circumstances. This set should be incorporated into the system, but there should be a changeover valve to switch between supplies. Both the airline and the personal BA set (unless an escape set) should have pressure whistles.

Something doesn't sound right with the adjustment of your overall set - are you using a compatible system or have you just thrown an independant BA set & airline system together?.

if you are an industrial user, I suggest you ask ARCO for advice as they deal with a lot of airline and BA systems

What worries me is the training issue - i.e. you shouldn't need to be asking on here - your employer (be it FRS or industrial) should have provided (either internally or via approved training provider/OEM) full training in all types of BA/airline and combinations , hold the instruction manuals from the OEM (that should answer your questions) & have a planned preventative maintenance regime by competent persons

Thank you Anthony for the info. I'll  definately check with my training side. But just to get info from other sources. And I believe its its the compatibility issue. i'll try again.
Cheers
