A smoke detector is a life-saving device designed to detect smoke and alert occupants to potential fires before they escalate. Although these safety gadgets are small in size, they play a huge role in determining the safety of your home and workplace. This smoke detection system can keep people safe by providing early warnings that allow people to evacuate and firefighters to respond quickly. This blog explains the different types of heat and smoke detection systems and explains how they work. We’ll also share some of the best smoke detectors that provide optimal safety. 

Types of Smoke Detection Systems

There are different types of smoke detection systems and they have their own way of detecting hazards. However, they can be divided into two main types–ionization and photoelectric detectors. Let’s take a closer look at what they are and how they work.

• Ionization Smoke Alarms

This heat and smoke detection system is great for detecting fast-flaming fires. Such fires often contain materials that ignite quickly, such as paper and wood. Moreover, this smoke detector contains a tiny amount of radioactive material that ionizes the air inside the detector. So in case of smoke in the area, the particles enter the detector and disrupt the ionization process, triggering the alarm.

How Ionization Smoke Detection System Works

This smoke detection system works with the help of two plates inside it. The plates have an electric current flowing between them. The radioactive material, usually Americium-241, ionizes the air, creating a conductive path for the current. So, when smoke enters it, it disrupts that flow, and this causes the current to drop. When the electrical current drops below a certain level, the detector senses this change and triggers the alarm.

• Photoelectric Smoke Alarms

Photoelectric smoke alarms are better at detecting slow, smoldering fires that burn for a long time. These fires are capable of producing a lot of smoke before bursting into flames. These types of fires are common with upholstery, bedding, and other materials that burn slowly.

How Photoelectric Smoke Detection System Works

The photoelectric smoke detector works with the help of a light source and a sensor. When smoke enters the chamber, it will scatter the light beam in the detector. As a result of this change in light, the sensor will be triggered, which activates the alarm. Since this type of detector is better at sensing thick, smoldering smoke, it can provide an early warning before a fire fully ignites.
