posee alarma de llenado ? ejemplo, ¿ si lo graduo a 32 psi , avisa con sonido cuando llega a esa presion ? ¿ para automaticamente ?

Sí, se alarmará y se detendrá automáticamente.

How do you know when your tire is at the right psi as this is on the wall and I am outside?

It beeps loud enough to hear. I have mine mounted on the inside wall of my garage and fill the tires on a diesel zero turn mower outside and can hear it overthe engine noise. It will also stop filling when it reaches the set pressure

Does this unit cycle on/off while filling to check press? Does it automatically stop filling or deflating when set press is reached?

It will beep when it gets to set pressure and will do for at least 3 times that is as long as it took me to unhook it, and I will air semi-truck tires to 120 or 130 and before putting them on recheck air pressure before installing them if I set the pressure to 105 and they are filled to 120 it will deflate the tire to the set pressure and beep when at set pressure

Want to use this when mounting tires in my shop. Does the unit have good air flow volume? How long does it take to inflate an average tire?

I have one in my shop at home. I use it to fill semi tires. The thing works great, you set the pressure and it beeps when it's done. If the tire is over inflated it will reduce the tire pressure. To put 20 pounds in a semi tire it takes a minute or two.
