How many kwh would a smoke detector use that is 120 VAC 60 HZ 80mA?

kW = I x E x pf/1000. Take this figure and multiply it by the amount of hours that the smoke detector is in operation. pf = power factor.

Where can you buy smoke detectors?
Check out the smoke detector installation section of this link for more information. Its in section 3. There are many guidelines that may vary from state to state, so you may have to get a local codebook for your state or territory.
What equipment would I need for radon testing?
You need a radon detector to perform radon testing. Essentially it's a geiger counter. Radon is radioactive and you locate it just the same way. Many radon alarms are available for areas where Radon is a problem. You would need a radon detector for radon testing. You can purchase one from amazon.com for $130 shipped. http://www.amazon.com/dp/B000CEAY64
Should you have a natural gas detector in your home, and if so where can I purchase one?
Every home should have a fire detector and a natural gas detector. Natural gas can cause many health problems, and if breathed in for too long will be fatal. Go to www.instrumart.com or www.amazon.com for different products and prices available.
What's the best option for radon gas detection?
You can buy a radon gas detector at many sites and mount them at your home. At amazon.com they are $130. Try http://www.amazon.com/Safety-Siren-Pro-HS71512-Detector/dp/B000CEAY64
How many wired doorbells in US?
most of them before electricity was common there were knockers and mechanical bells one of the worst possible wireless technologies is in the burglar/fire alarm systems with every window door and smoke heat glass break detector requiring a battery it becomes rather tedious replacing batteries. most alarms rely on wired phones they tend to function when there is a power failure.
Is it illegal to cover a smoke detector?
If you mean to interfere with a smoke detector on an airplane, that would be a federal offense. If you cover up a smoke detector in your own house, that would be not be smart to do but is likely not illegal. For rental properties or office buildings, you would probably have to check local building and safety codes to find out if it is illegal, but covering one there would not be a smart thing to do. Many codes in public buildings require working detectors.
How many square meter does the smoke detector cover?
83m^2
How many smoke detectors are needed in a house?
Ideally, a smoke detector for every room should be in place.
How does a fire alarm detect smoke?
Smoke detectors work in several ways. A point to point smoke detector detects smoke when the beam projected by the transmitter is obscured in a measurable way and detected by the receiver. A photoelectric detector sees smoke particles inside the detection chamber of the smoke detector because light inside the chamber is scattered in a measurable way. An ionization smoke detector detects smoke because the smoke particles change the 'charge' on the detection plate inside the smoke detector.
How many type of smoke detectors?
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.

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.
What is smoke density?
measures how many (usually) parts per million (ppm) of whatever smoke/gas/etc is being looked for. For instance a smoke detector looks for X ppm of smoke in air, or a CO2 sensor measures the ppm of CO2 in air - ppm is a measure of density.
What are four sentences for the word smoke?
You can often smell smoke before seeing any flames.The smoke billowed into large clouds that drifted above the city."Do you smoke," the doctor asked her patient.Smoke typically contains many chemicals.
What is a smoke alarm made out of?
Most smoke detectors work either by optical detection (photoelectric) or by physical process (ionization), while others use both detection methods to increase sensitivity to smoke. For the alarm part, in many single family detached and smaller multiple family housings, a smoke alarm is often powered only by a single disposable battery. An optical detector is a light sensor. When used as a smoke detector, it includes a light source (incandescent bulb or infrared LED), a lens to collimate the light into a beam, and a photodiode or other photoelectric sensor at an angle to the beam as a light detector. In the absence of smoke, the light passes in front of the detector in a straight line. When smoke enters the optical chamber across the path of the light beam, some light is scattered by the smoke particles, directing it at the sensor and thus triggering the alarm. An ionizing detector type of detector is cheaper than the optical detector; however, it is sometimes rejected because it is more prone to false alarms than photoelectric smoke detectors. It can detect particles of smoke that are too small to be visible. It includes about 37 kBq or 1 µCi of radioactive americium 241, corresponding to about 0.3 µg of the isotope. The radiation passes through an ionization chamber, an air-filled space between two electrodes, and permits a small, constant current between the electrodes. Any smoke that enters the chamber absorbs the alpha particles, which reduces the ionization and interrupts this current, setting off the alarm. From Wikipedia.

How many lives has the smoke detector saved?
A self-contained residential smoke alarm lasts about 12 years, but must be replaced no later than 10 years for safety. Some units now have a 10-year battery life or other features that cannot be extended, thus requiring it to be discarded and replaced at 10 years.
