Seperate areas with two key pads. How to handle the input delay

Hi, i have following setting at a german locationFlat:1 base station1 key padsome door contactsbasement1 key pad1 door contactCurrent situation:If i enter the flat door, the input delays gets activated. Both key pads play the input delay sound.What i want to achieve:I want to serpate the sound notification for the input delays. So if I enter my flat only the keypad in my flat should play the input delay notification.If i enter my basement, only the keypad in the basement should play the notification.So how is this possible?
