John – The decision to require a pin to code off troubles was due to UL Listing preparations for commerical requirements. We do plan to expand the options to include disabling this requirement and audiable trouble beeps in general.
The Keypad are equiped with a “Quite Time” Option that is ON by default. Quite time is configurable but we default it to run from 11pm to 6am. During this time, trouble beeps are silent. You can view this in Keypad Settings. It is configuable per keypad in the event you what a bedroom keypad to be quite at different times than a entry keypad.
