You may want to disable announcements for keypads in certain bedrooms (announcements like "Nigh Mode, Security Mode, doorbell chime and other programmed announcements)
Go to the keypad for which announcements are to be disabled, and go to Program Menu 3,1.
Press 1 to enable announcements, 0 to disabled them on that keypad alone.
This is also described in the User Manual. To selectively disable selected keypads, say based on time or in certain modes, use Action 139 (Keypad Announcement Enable/Disable).
This action allows any keypad ID to be enabled or disabled for announcements
