Will smoke alarms work if they are upside down?

my smoke alarm was too sensitive to my cooking/burning contained by the kitchen so i took it down and set it in a soaring place (on top of my secretary desk). I realize now its upside down, and since smoke travels up.. will it still work?


Answers:    They work contained by any orientation, but entail to be high up, to do you any obedient.

I wouldn't have a smoke detector surrounded by a kitchen anyways, due to film departed from grease and oil contained by the air. The motion picture left contained by the detector, will attract dust and could render the detector useless or inaccurate.

Find a location hard by the kitchen, but not in it.
Yes, but by the time it registers any smoke, you will enjoy an inferno going.

Smoke rises, which is why smoke detectors are at the highest points possible.

Do yourself a favor and reinstall the detector where on earth it's supposed to be, and then cram how to cook without torching the food.
Not unless the desk is smoking...
The smoke detector wishes to be high and surrounded by its normal situation for two reasons.

High because it is a cheap ionization type,which is lookiing for smoke from a hot fire. When upside down, it is a dust collector, and dust can generate it false alarm.

A bit of explanation on the "cheap ionization" bit. Ionization-type detectors work best on the smoke from flaming fires. Photoelectric-types work almost as well on smoke from flaming fires, and much better on smoke from smoldering fires. Photoelectrics cost more, so most ethnic group buy ionization-types. Sadly most organizations (including fire departments) who grant away detectors, are not sufficiently aware of the differences, and chose to give the smaller quantity effective ones.
