Warning sounds

[Debowing 12]

I am en route cruising at FL 320, I get a warniing sound, I am not sure what it may be, perhaps the pressurization? There is no visual warning light just the non stop sound.

Sounds like the cabin is not pressurised. There is a button to silence the horn between the two cabin pressure gauges on the FE panel. 

 

To pressurise the cabin, you need to turn on the manifold pressure switches (to "LOW"), turn on the cabin compressors and set the cruise altitude on the gauge. I'll post a screenshot in a moment to show the relevant controls.

 

Also, please read the the sticky at the top of the forum.  Not much is going to work properly without XML tools installed.

Thanks the pressurization alarm sound has been silenced by this circular button and I have re-positioned the manifold switches to LOW.

Yes that’s right but I should have set these before departure I believe.

Correct, but better late than never. 

 

To do it by the book you are supposed to have only two cabin compressors on for take off and then turn on the other two later when you have a chance.  Two are enough to pressurise the cabin.
