What is the difference between a smoke alarm and a smoke detector?

There are a number of differences between a smoke detector and a fire alarm system. A smoke detector simply acts as a sensor and detects the smoke while a fire alarm system acts on it. A fire alarm system has a number of different devices all joined together to give your building protection from fire.

Secondly, which type of smoke detector is better? Photoelectric Smoke Detectors are best at detecting the large particles typical of smoky, smoldering fires but poor at detecting fast, flaming fires.

Smoke detectors must be connected to a building's fire alarm system and are NOT a stand-alone unit. Put simply, a smoke detector senses smoke only and must be connected to a fire alarm system control panel. Smoke detectors are a detection device only – not an alarm.

How do I know what kind of smoke alarm I have?

If you are unaware which type of smoke detector you have in your home, now is the time to check. You can do so by taking the smoke alarm down and look at the back for either “Photoelectric” or “Ionization,” or a symbol with the letter “P” or “I” on the back.

How much radioactive material is in a smoke detector?

Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year. This is well below the background radiation level of about 360 millirems a year. If a smoke detector contains radioactive materials, a printed notice on the packaging will say so.

Do smoke detectors detect vape?

After all, e-cigs produce vapor not smoke, so in theory, an e-cigarette won't set off a smoke detector because there's nothing to detect. There are three commonly used smoke detectors available, and the likelihood of vapor being detected as smoke by them depends on which kind is being used.

How do you cover a smoke detector?

Rip off a piece of aluminum foil to fit over the smoke detector and around its sides. Wrap the piece of aluminum foil around the smoke detector. It should stay by itself, but if it doesn't, wrap a large rubber band around it.

What is an ionization smoke alarm?

Ionization smoke alarms are the most common type of smoke alarm and are quicker at sensing flaming, fast moving fires. This type of alarm uses a small amount of radioactive material to ionize air in an internal sensing chamber. This scattered light is detected by the light sensitive sensor which sets off the alarm.

When there is an actual alarm, the unit that detects the smoke triggers all the others to sound an alarm. Different manufactures use different signalling schemes for this common wire. Other units may or may not work together, or may mix up a smoke alarm versus a carbon monoxide alarm, so don't mix them!
