Just installed with DSC PC1616, how to arm Stay Mode?

[ppeewang]

I can't figure out how to arm the alarm in stay mode on the Envisalink admin web interface. Any ideas?

EDIT: Ok so by default entering my code will enable stay mode on the panel if I don't exit the premises. If there a way to arm in away mode from the interface ?

When you select "ARM", just click on Stay Arm instead of using a code
