There are three available types of household smoke detectors — ionization, optical (photoelectric), and combined. They are very cheap and are available everywhere. The combined detectors are effective at detecting slow-burning as well as flaming fires, both common types of fire in the home.

What is the difference between ionization and photoelectric smoke alarms? Ionization smoke alarms are the most common type of smoke alarm and are quicker at sensing flaming, fast moving fires. ... A photoelectric type smoke alarm consists of a light emitting diode and a light sensitive sensor located in a sensing chamber.

The 1st-generation Nest Protect has a basic photoelectric sensor. The 2nd-generation model still only has a photoelectric sensor, but Nest says that it's greatly improved so that it can detect other types of fires that ionization sensors normally detect, getting rid of the need to have two separate sensors.

Fire detection systems are those that detect hazardous conditions. ... Fire suppression systems are those that control or contain hazardous detection and suppression systems decrease loss through prompt notification and early mitigation and control of the fire.

An optical beam smoke detector is a device that uses a projected beam of light to detect smoke across large areas, typically as an indicator of fire. They are used to detect fires in buildings where standard point smoke detectors would either be uneconomical or restricted for use by the height of the building.

Ionization chamber and photoelectric smoke detectors are the two most common types. Both work very well and are safe to use. ... They react quickly to fires that give off little smoke. Ionization smoke detectors expose people to a tiny amount of radiation—about 1/100 of a millirem per year.

There are actually five main types of fires. Fires can be classified in five different ways depending on the agent that fuels them: Class A, Class B, Class C, Class D, and Class K. Each type of fire involves different flammable materials and requires a special approach.

Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Both monoammonium phosphate and sodium bicarbonate are commonly used to fight this type of fire because of their nonconductive properties. Fire extinguishers are classified by fire type.
