An Historical Overview of Fire Alarm Systems and Automation Since the invention of fire alarm systems, fire alarms have advanced from simply ringing bells to more complex other automated systems, which can connect with the advanced technologies of contemporary buildings. The development of fire alarm systems has enhanced fire identification and reaction to such incidents, besides increasing the safety of habitation and industrial units. In the following article, the author compares fire alarm systems over the years, the effects of automation technologies, and leading brands of fire alarms for the future. What is Fire Alarm System and Its Brief History Fire alarms have been used since the mid-nineteenth century. The primary forms of fire alarms included hand crank sirens/bells that used levers to alert the people in the building of fire. Such systems were elementary, which meant one had to manually set off the alarm as soon as they spotted a fire. Even in the 1900s, electric fire alarm systems were installed, which can be considered one of the biggest jumps. https://ramautomations.com/ These systems were equipped with heat sensors and manual pull stations and were a better way of detecting the fire and passing the word around. However, these early systems were simple, and many had direct interfacing with human operators to optimize their performance.
