Best place to put it would be back on the shelf at the store.

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!


For what it's worth, that Nighthawk won't alarm or even go off until CO has
reached danger levels. As I recall, they won't alarm until CO reaches 50PPM
for an eight hour period. That's not good enough for me, but it's good
enough to satisfy UL2034.

The card sitting in front of me tell me that (supposedly) 9PPM is acceptable
in a living space. 50PPM is the max concentration over an 8 hour period.
400PPM will give you frontal headaches in 1 to 2 hours and life threatening
after 3 hours. 800PPM will cause nausea and convulsions, death within 2
hours, etc, etc.

A lot of people don't like the low level alarms, but that's what I recommend
to customers. Your money is better spent on having your heating system
checked on an annual basis.
