For the best protection, both types of alarms or combination ionization-photoelectric alarms, also known as dual sensor smoke alarms, are recommended.
How do smoke alarms use radiation?
Ionization chamber smoke detectors rely on radiation to “ionize” the air inside the chamber. A radioactive source “decays,” or sheds particles and photons from unstable atoms. The particles interact with neutral air molecules flowing through the chamber.
What is the triangle for fire?
The fire triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite: heat, fuel, and an oxidizing agent (usually oxygen).

What do smoke detectors detect?
A smoke detector is an electronic fire-protection device that automatically senses the presence of smoke, as a key indication of fire, and sounds a warning to building occupants. Commercial and industrial smoke detectors issue a signal to a fire alarm control panel as part of a building’s central fire alarm system.
What are the two types of fire?
Classes of fireClass A – fires involving solid materials such as wood, paper or textiles.Class B – fires involving flammable liquids such as petrol, diesel or oils.Class C – fires involving gases.Class D – fires involving metals.Class E – fires involving live electrical apparatus. (More items…
How many types of smoke detectors are there?
Most homeowners don’t know that smoke detectors come in two types: ionization smoke detectors and photoelectric smoke detectors.
Can smoke detectors detect vape?
Despite this, they can still set off a fire alarm if you blow vapor directly into it. All smoke alarms are sensitive to small, airborne particles. … However, just like smoking, vaping is unlikely to trigger a fire alarm if only one or two vaporizers are in use and you don’t aim directly at a smoke detector.
