Accenta8 mini controls?

Hi, my daughter has moved into a new house and cannot figure out the above alarm. The main box is in the garage with a seperate keypad with zone info etc etc. However in the house there is just a keypad with 0 to 9 on it and a yes button and a no button. Can anyone help me understand how to set the alarm using the keypad in the house. The code works on that keypad to stop the alarm when i "tampered" with it.
