So I have set up two keypads and two programs (P1 & P2) set. P1 will be used to enter/exit and sets all used zones. P2 is used for nighttime with one PIR disabled and set for silent timed. The 'nighttime' keypad is upstairs in hallway and the idea is that last to bed will set P2. Only thing is that the keypad beeps on code entry and before getting P2 selected is again does a few beeps. Is there any way to completely set the keypad to silent so that any interaction will not disturb other occupants who may be sleeping? I can't find a setting in the manual. Thanks.
