Cheap and effective when maintained properly.
Smoke detectors will run out of battery over time as they are not wired in to the houses electrical system.
Statistics show that far fewer people die in house fires when smoke alarms are present.
When the smoke alarms are placed to close to bathrooms steam may interfere with the detector, triggering false alarms.
Ionization detectors seem to respond better with high flames which could be a problem under certain circumstances.

What gauge wire is used to run smoke detectors?
14-3 Is the standard wire use for residental smoke detectors.
What are the advantages for smoke signals?
The smoke spreads very far.
How often should you test your electrical equipment?
Electrical equipment should be tested every 6 months like your smoke detectors and your furnace . Electrical fires are the 3rd leading cause of fires in Canada, so test ,test test.
What are smoke and CO2 detector code requirements?
The codes are local and may be different in each jurisdiction. Check with the local fire inspector. At any rate I recommend both, especially if you have a gas fired heating stove or fireplace for the CO2 detector. I have combined detectors everywhere. The other question is if local code requires a hard wired detector with battery backup.
The M157 smoke generator set uses what kind of smoke generator?
gasoline
Was there americium in the first smoke dectores?
Alpha particles from americium ionized the air. An air with smoke has a different ionization, ionization currents which are also different are measured, compared and the detector (which was before calibrated) is ready ! The americium smoke detectors (with ionization) are not the first smoke detectors.
What are the common smoke-sensing technologies?
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization
What are some of the smoke-sensing technologies we used?
There are two smoke-sensing technologies commonly used in residential smoke detectors: photoelectric and ionization
How does the sensor control smoke detector?
The smoke detectors use the photoelectric effect or a sensor based on the ionization differences between smoke and air.
What does americium do in smoke detectors?
Yes, americium is used as ionizing source in smoke detectors.
Why is the isotope americium 241 safe to use in smoke detectors?
An ionization type smokes detector with 241Am is sure if you don't destroy this device.
How is americium 241 used in smoke detectors?
Americium-241 being radioactive - emit alpha particles - is used as a source to ionization of air.
Explain why americium-241 would be an ideal isotope to use in a smoke detector?
Alpha particles from americium ionized the air. An air with smoke has a different ionization, ionization currents which are also different are measured, compared and the detector (which is before calibrated) is ready !
Is technetium a synthetic element used in smoke detectors?
Americium is the radioactive element used in ionization type smoke detectors. It is a by-product of the nuclear power industry. In the device, it is present as the oxide, which is rather chemically inert and has a high melting point. As a small capsule enclosed in metal foil. Your exposure to radiation from an ionization smoke detector is smaller than your exposure received by sleeping alongside your partner who is converting K40 into Ar40.
Do smoke detectors use infrared rays?
Photo-electric (PE - as opposed to the ionization type of) smoke detectors do indeed use the reduction of light energy at the receiving end to "Sound The Alarm". Whether or not this is IR energy, I can't say. Might someone else please fill this in? Thanks.
How Do smoke alarm Work?
There are 2 types of smoke detectors: ionization detectors and photoelectric detectors. Although they use different mechanisms both essential set off an alarm when smoke obscures the line of sight between 2 objects within the detector.
What are the advantages and disadvantages of a halving joint?
A joint is a herbal cannabis that you can smoke
