There are two types:
- ionization - a tiny piece of Americium ionizes air in the transducer. a tiny electric current passes through this ionized air. smoke deionizes this air, reducing the current and tripping the alarm.
- photoelectric - a light and photocell in the transducer looks for smoke. smoke reduces the light falling on the photocell, tripping the alarm.

What does americium do in smoke detectors?
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
Why the Americium is used in smoke detectors?
Americium is used in smoke detectors because it emits alpha particles that ionize the air, creating an electrical current. When smoke enters the detector, it disrupts this current, triggering the alarm. Americium has a long half-life, making it reliable for long-term use in smoke detectors.
What did the first smoke detector look like?
The first smoke detector was invented in 1890 and used a simple design with a bent bellows chamber filled with air that would expand when smoke entered. This expansion would trigger a lever mechanism to sound an alarm. It was a basic system with limited effectiveness compared to modern smoke detectors.
Do smoke detectors detect ciggarette smoke?
Yes, smoke detectors are designed to detect all types of smoke particles, including cigarette smoke. When cigarette smoke particles enter the detector, it triggers the alarm just like any other type of smoke.
How can I initiate the return process for a Kidde smoke detector?
To initiate the return process for a Kidde smoke detector, contact the retailer where you purchased the detector and inquire about their return policy. Provide proof of purchase and follow their instructions for returning the product.
