The first smoke detector was invented in the 1930s by Walter Jaeger
The history of fire alarm systems is a fascinating one. In 1852, Dr. William Channing, along with Moses Farmer, designed the first fire alarm system. This system comprised two fire alarm boxes, a key, and a handle. Operating it would alert an operator who would then pass the message to the fire station. The first electric fire alarm was invented in 1890 by Francis Upton, a partner of Thomas Edison.
In the 1930s, Swiss physicist Walter Jaeger invented the first smoke detector. Jaeger was attempting to invent a device that could detect poisonous gas. He expected the gas to enter the sensor and bind to ionized air molecules, thereby altering the electric current in the circuit. However, his device failed to detect small concentrations of gas. Out of frustration, he lit a cigarette and noticed that the smoke particles had altered the current. This discovery led to the creation of the modern smoke alarm.
At the turn of the 20th century, other detection devices such as smoke and carbon monoxide detectors were invented, which would eventually become essential components of modern fire alarm systems. However, these early detectors were often too expensive or too large for viable use in homes or businesses. It wasn't until 1965 that the first affordable home smoke detector was invented by Duane D. Pearsall and Stanley Bennett Peterson. These early home models were battery-powered, fire-resistant, and shaped like beehives.
Over time, improvements in manufacturing and technology led to the development of more advanced fire alarm systems. By the 1970s, the first "single-station" detectors, similar to those found in homes today, were introduced to the market. These detectors were battery-operated and could be easily installed and replaced. Today, fire alarm systems have become even more sophisticated, incorporating voice evacuation systems that provide specific instructions during a fire emergency.
