Home Fire Alarms

All homeowners should install some form of security system in their home, and there are three things which would qualify as a security system that can be done easily: A fire extinguisher and a fire alarm are the two easily placed of the three security system options a homeowner can implement. The third and arguably the most common and most important type of security system include fire alarms. Fire alarms are designed to alert a homeowner in the event that a fire could be present, and it does this by detecting smoke in a variety of ways, depending on the type of fire alarms installed.

History of Fire Alarms

Fire alarms and now usually required by law.

In 1890, the first fire alarm security system was invented by Fernando J. Dibble and Francis Robbins Upton. Initially, they were not available widely, and the technology upon which it was designed was somewhat faulty. Over time, this fire alarm security system was modified, and they would eventually become ready for the public by the 1960s. This was because of a huge price drop; prior to that, only the wealthy businesses were able to have them. By 1967, home fire alarms became a reality with battery power for better and easier installation, bringing the price down to an affordable level that work for people even today.

Significance of Fire Alarms

The home fire alarm security system is certainly an improvement as far as home safety is concerned because it provides a good amount of time for someone living with one to have a fair amount of time to react in the event that a fire occurs somewhere inside of the house. The significance is to provide people a peace of mind and know that even if everybody in the house is currently sleeping, they will still receive an alert should a fire break out in their home. This security system has, to date, become an invaluable part of a home, having saved countless homes and lives.

Function

Home fire alarms function by alerting whoever is home in the event of a fire. it accomplishes this by detecting an unusual level of smoke and sounding a very loud alarm that is designed to be heard from individuals across the home and wake them up should they be sleeping. Normally, fire alarms will run on batteries so that they can safely work even if the power is out in the house. Smoke is detected in a variety of different ways depending on the fire alarm design, but they will also wind up with the same result.

Type of Fire alarms

There are two primary types of alarm security systems, and they are categorized by the way they detect smoke. The first contains an optical detector, which uses a laser light to shine over something called a photoreceptor. As the smoke protrudes the alarm, the light becomes displaced and alerts the siren. The other type of alarm uses something called ionization, where radioactive material ionizes the air and creates an electrical charge. When smoke dissipates it, an alarm sounds.

Risk Factors
As far as a home fire alarm is concerned, there are typically no real risk factors other than a small one that involves the handling of an ionization fire alarm on the inside. As it was previously stated, the way this type of fire alarm operates is due to having some radioactive material inside of it. While it is too small to affect anybody who happens to stand near it, it is best to never touch the inside of fire alarms directly as it can burn and damage exposed skin.
