How to Turn off security features when device is found

Hi,
I got that to locate my phone I have to send a text to my number saying lost from the friend numbers I have chosen for the anti theft features to get activated. Once I find the phone how do I turn the features off? Also, is there an option to play only siren sometimes or to have two different anti theft features profiles? If my phone is misplaced I would first like the siren to sound (useful when phone is on silent) and if I am sure its stolen I would then like then data erased and receive sms from my phone about the new location. Is it possible to do this?
Thank you in advance!
