Then it wouldn't be a smoke detector, but there are fire alarms that are triggered by temperature.

Smoke detector for cigarettes?

In such smoke detector an analog address is given to smoke detetctor which can be directly read at the fire alarm panel.


What are the advantages of hard wired versus battery only smoke detectors?

If the battery dies the smoke detector sill works, that the biggest advantage to using hard wire.


Why do nuclei that emit alpha particles such as americium-241 are safe to use in smoke defectors?

Nuclei that emit alpha particles, such as americium-241, are safe to use in smoke detectors because alpha particles can only travel a short distance through air and are easily stopped by a thin sheet of paper or clothing. The radiation emitted by the nuclei is low energy and poses no harm to humans. Additionally, the amount of americium-241 used in smoke detectors is very small, further reducing the risk.


Can you fool a motion detector?

yes you can disable it by covering the motion detector. remember the detector works with heat and if is cover no signal will be register only a ligth switch will over rite the sensor if you turn the ligth on is going to stay on all ways is not turning of that's y you can disable it


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.

Is it illegal to have a smoking hotel room without a battery in the fire alarm?

Normally in a hotel you would not have battery operated smoke alarms. You would have a mains powered fire alarm system connected and networked throughout the hotel building. In this case, heat detectors may be installed as they do not detect smoke...only heat. Although, removing the detector head or disconnecting the detector is illegal and dangerous as it may disconnect the rest of the fire alarms in the hotel and for your electrical safety.

Does the ADT home security system cover fires, or only intruder alarms?

ADT will only cover intruders. Leave fires to your smoke detector.


Why do batteries in smoke detectors have to be replaced in 6 months?

They don't. Normally the 9 volt alkaline batteries in a smoke detector need to be replaced every year. If yours needs to be replaced every 6 months then something is wrong. If you are using a standard battery and not an alkaline battery it may only last 6 months. Use nothing but alkaline batteries. You sould hear a chirp from the detector when the battery needs replacing. A hard wired smoke detector has a battery back-up that should last around 2 years. If it only lasts 6 months then there is no power to the smoke detector and it is wired wrong or the wiring has come loose. The only reason to recommend changing batteries every 6 months is bacuase people tend to not change the batteries as they should. It has been proven by tests that about 35% of smoke detectors in homes have dead batteries.


What are Two type of heat detectors are?

They are: -Rate of Rise -Fixed Temperature Rate of rise detectors can be adjusted to different temperature settings to which detect heat. Once the temperature in that area reaches your chosen point, it will activate the heat detector. Fixed Temperature is when you buy a heat detector, it only has one fixed detection point on it. So you cannot adjust this.


Why does your car only blow heat when moving?

the smoke comes out the rear of the car in a pipe. the smoke comes out only when the engine is on. you do not have to be moving to have smoke come out. just the fact that the engine is on creates smoke due to the byproduct of the fuel and energy.


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 do you convert heat into sound?

For example, if you have a lot of heat in one place, you can get an explosion, which is accompanied by a sound. Note that in general, it is only possible to extract useful energy from heat if there is a temperature difference.

Do rental car have smoke detect?

no they do not. Neither does any other car.I received a call just this morning from a car renter who had a quest who smoked in the rental car he had to turn in. He stated that the tape (Smoke detector) had turned a deeper color, indicating someone had been smoking. I was unsure of the tape system he was speaking of, and the only suggestion I had was to not only shampon the carpet and upholstery, I would have to sanitize the air circulation systems to eliminate the smoke odor. I'm researching the smoke detector systemthe renter was speaking of. So I suppose there is a smoke detector in some rental cars. Stay tuned.Next Answer:If you are wondering how you might smoke in a rental car and not get caught, you're out of luck. I can always tell when a customer has smoked in a car. The smell gets into the upholstery and the interior plastics and is very obvious to people who don't smoke. You might not smell it, but we can.And if that smell is so hard to get out that we have to send the car to a detailer for a $300 shampoo job, you can expect to be billed for it. :)
