Hello,
After shopping around much, purchased a nighthawk digital for $33 from
wal-mart.
These are expensive and I'm wondering if the best placement would
be high in the hallway near the bedrooms. There are 3 bedrooms that are
occupied.

Is this a good idea?

Should it be directly under a vent?

Thanks much!

Read The Fine Manuals (RTFM) that came with the detectors. They go
into detail on where to and where not to place them. Head level
(while sleeping) in bedrooms are good ideas as I recall from reading
my own.

You got a great deal on those detectors. Target sells them for around
$50.
