The technology behind it involves using a radioactive isotope of americium usually, it’s Americium 241 to ionize the air inside a chamber and, if the sensor detects any changes in the air, it triggers the alarm. The disadvantage of using such type of detectors is that they are more prone to false alarms such as when you’re cooking or when there’s a large amount of steam. The photoelectric sensor is more sensitive to larger particles which are specific to slow burning, smouldering fires which could originate from a forgotten cigarette on the couch, but the sensor is not as sensitive to flaming fires. The way this type of detector works is that it uses a light source can be infrared, ultraviolet or visible which points away from the sensor, but, in the event of smoke entering the small chamber, the light particles will be scattered, therefore, some will hit the sensor and trigger the alarm. This type of technology is used a bit different in larger spaces, where the light beam is directed towards the sensor, but if the intensity of the light drops under a certain level due to smoke, the alarm will be triggered. 2.
