Fire detection using ionization smoke alarms

Fires can occur for a variety of reasons and can occur in an arbitrary part of your home or office. In such circumstances, detection systems such as smoke alarms are often a major step in fighting fire. With a similar mission to minimize loss of life and property due to a fire, fire protection companies in bangalore home and business owners often choose to install smoke alarm systems. Since its invention, smoke alarms have proven to be critical in early fire detection. Having a well-installed and well-maintained smoke alarm system means a guard operates 24 hours a day to warn you, your family or your employees of the first fire situation. Although smoke is an essential by-product of a subsequent fire, different types of fire mean different types of smoke, which in turn translate into differences in smoke detection systems. Let's take a look at a type of smoke alarm known as an ionization smoke detector and explore the technology associated with the device.

How does ionization smoke detectors work?

The two main parts that make up the smoke detector are the smoke detector sensor and a built-in sound alarm system to notify people of the fire, Fire Protection Services in bangalore In the case of an ionization smoke detector, the sensor is replaced with an ionization chamber containing a small amount of radioactive element called americium-141. By applying the principle of ionization with the use of two metal plates and radioactive materials, an electric current is formed inside the chamber. This small amount of current is generated by free electrons with a negative charge and positively charged atoms. When smoke from a nearby fire enters the room, it cuts off the current flow. Smoke particles stick to and neutralize the electrically charged particles. As a result, the camera suffers from a current decrease between the panels and immediately activates the audio notification system, which is usually a siren or horn.

It should be noted that the radioactive materials kept in the ionization chamber emit only a small amount of alpha radiation. This type of radiation is so weak that it can barely penetrate a piece of paper.

Where and when to install it?

Among two types of smoke alarms, the ionization type easily responds to a fire. Fire is classified as such when the ignition sources are wood, paper, or flammable liquids. Despite the fact that flame fires produce very little smoke compared to slow-burning fires, they are not a problem for ionizing smoke detectors, because they are able to detect even a small amount of smoke. Since flame fires generally occur in homes, it is advisable for homeowners to choose an ionization smoke detector. Today, the market also features compact smoke alarms that adapt to all types of fires. Fire safety departments such as NFPA and USFA suggest that the location of smoke alarms should be prioritized over the type of detection system.
