How do smoke detectors detect smoke?
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
Who invented smoke detectors?
king man
Why were smoke detectors invented?
To warn and protect people against fires.
Why is curium 242 not suitable for use in smoke detectors?
It is radioactive. ------------------------------- Incorrect answer: americium-241, the usual isotope in smoke detectors is more radioactive.
How is radioactivity used in smoke detectors?
There are two types of smoke detectors:Photoelectric Smoke detectorsIonizing Smoke DetectorsIonization smoke detectors are more commonly used. The smoke detector uses an ionization chamber and a source of ionizing radiation to detect smoke.Alpha particles are emitted from from the chamber, which ionize the air, so that the air conducts electricity and a small current flows.If smoke enters the alarm, it absorbs the alpha particles causing the current to reduce, and the alarm sounds.Generally, smoke detectors use a weak source made of Americium-241 (241Am95).Note: Alpha particles are the nuclei of a Helium Atom (4He2).
Does radar detectors beep?
Most will beep when they receive a signal.
Why do smoke detectors make a beeping noise when the electric goes off they are not hooked to any electric?
When the electricity goes out, a smoke detector may make a final beep as it's capacitor is discharged, as a warning. If the smoke detector has a battery backup, some detectors will beep just to let you know the power is off, and some other units will only beep when the power is off AND the battery is low. Usually there is a legend on the back of the unit that will tell you what the different beeps mean.
Why does your smoke detector beep only at night?
Incase you are sleep and a fire starts the smoke detector will wake you up
Will a short circuit cause smoke detectors to beep after resetting the circuit breaker?
If your smoke detector is bleeping you have a serious risk of fire and the circuit breaker must not be reset until the fault that caused it to trip is investigated.
Where are Masterguard smoke detectors made?
Masterguard Smoke Detectors are made in Coppell, TX.
What are smoke detectors?
Smoke detectors are devices that detect smoke. They are used as warning devices in houses to warn people of fire.
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/
Can smoke detectors detect smoke in the ciling?
No
Are smoke detectors and smoke alarms the same?
no
How long has americium been used in smoke detectors?
Americium become to be largely used in smoke detectors after 1970.
How do smoke detectors detect smoke?
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
What year were smoke detectors invented?
Smoke detectors were invented in the year 1967. :P
