Where to install a buzzer if you want it to work (6)
I believe the answer is:
apiary
This clue might be a double definition.
'where to install a buzzer if you want it' is the first definition.
Although both the answer and definition are singular nouns, I don't understand how they can define each other.
'work' is the second definition.
The definition and answer can be both man-made objects as well as being singular nouns.
Perhaps you can see an association between them that I can't see?
'to' is the link.
(Other definitions for apiary that I've seen before include "Place where bees are kept for profit" , "Collection of beehives" , "Place for keeping bees" , "Place to keep bees" , "Home for bees" .)
