How they work: Ionization-type smoke alarms have a small amount of radioactive material between two electrically charged plates, which ionizes the air and causes current to flow between the plates. When smoke enters the chamber, it disrupts the flow of ions, thus reducing the flow of current and activating the alarm.
Can smoke detector detect cigarette?
Yes. Yes they can. That being said it takes a good amount of smoke in an area to set off most detectors. If you smoke one cigarette in a larger room and aren’t close to the detector it probably won’t set it off.
How does smoke set off the alarm in a smoke detector?
Ionization smoke detection employs the use of ions and electrons that whizz around electrodes. When smoke enters the ionization chamber, it sticks to the ions, which disrupts the chemistry and activates the alarm.
What are the 3 types of smoke detectors?
There are three types of smoke alarms, ionization, photoelectric and a combination of the two which is commonly called a “dual” detector.

What is the difference between smoke detectors?
Ionization smoke alarms tend to respond faster to the smoke produced by flaming fires than photoelectric smoke alarms. Photoelectric smoke alarms tend to respond faster to the smoke produced by smoldering fires than ionization smoke alarms.
Do all smoke detectors have the same plug?
Most hard-wired smoke detectors have a connection from the electrical wires to the smoke detectors that engages and disengages. The key is knowing what connector your smoke detector has so that you buy a new smoke detector with the same connector.
