There are basically two types of smoke detector;
one type measures the opacity of the air to literally "see" if there is smoke.
The other type tests for ionization that occurs when there is a fire. That type smoke detector uses a small radioactive chip to determine if freshly ionized smoke is present. It's a far more accurate means of determining the presence of fire and associated hazardous smoke.
Many smoke detectors use a combination of both detectors.
A separate type of detector is the carbon monoxide detector, which senses the presence of harmful carbon monoxide in the air. Most will even indicate the percentage of carbon monoxide. Note that carbon monoxide is typically present when a furnace or other heating device malfunctions.

What are the answers for fema IS 3?
many smoke detectors contain:
What are smoke detectors?
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
Can smoke detectors detect smoke in the ciling?
No
Are smoke detectors and smoke alarms the same?
no
Are interlinked smoke detectors a good idea?
There are several types of smoke detectors that can be used in the home. Interlinked smoke detectors can interlink smoke and heat detectors for better convenience. Also, wireless units can be configured specifically to your needs. More safety and smoke detector information can be found on: http://www.safelincs.co.uk/Smoke-Alarms/
What are the answers for fema IS-3?
many smoke detectors contain:
What kind of nuclear decay occurs within most smoke detectors?
Many smoke detectors use Americium-241, which emits alpha rays, to keep air ionized.
How many smoke detectors are needed in a house?
Ideally, a smoke detector for every room should be in place.
What control type includes environmental security devices such as fire alarms and smoke detectors?
Operational
Many smoke detectors contain?
a. Americium-241 Smoke detectors might have an ionizing chamber. If it does, the chamber holds a radioactive nuclide to ionize the particles in the smoke to set off the detector. Usually the radioactive source is americium.
