Why are smoke detectors important?
A smoke alarm is critical for the early detection of a fire in your home and could mean the difference between life and death.

How did the first smoke detector work?
Ernst Meli developed a device with an ionisation chamber that could detect gasses in underground mines. He also invented a cold-cathod tube that could amplify the small electronic signal created by the detection mechanism to a strength sufficient to trigger an alarm. The result was the ionisation smoke alarm.
What is the fastest reacting type of fire detector?
National Institute of Standards and Technology Consistent with prior findings, ionization-type alarms provided somewhat better response to flaming fires than photoelectric alarms, and photoelectric alarms provide (often) considerably faster response to smoldering fires than ionization-type alarms.”
