I have the parts sitting on the shelf beside me. A small 'glass speaker'
that can play a selected audio file when the bell push is depressed. I am
torn between a voice intoning "the bell has been activated, please wait"
and the start of 'Time' from Dark Side of the Moon.

I like the 2nd idea, but if it's like the couriers round here, they knock
the glass immediately after pressing the bell, even though they must hear
the bell which is in the hall.

Why does it matter if they do ?
