The way to differentiate the first and the second generation of Nest Protect is by verifying if it has a battery door the Nest Protect 1 does not have one, verify the back plate the second generation has a round backplate, while the first has a square plate and the easiest one is to look at the edges of the device the second generation has rounded corners all around the case, while the first gen has straight edges. Right now, on the market, there are three types of smoke detectors: those that use ionization sensors, those that use photoelectric sensors and lastly, those that use both type of sensors also called dual sensor smoke alarms. The Nest Protect, theoretically, falls into the last category, but things are a bit more complicated because it doesn’t have a ionization sensor, but it does use the Split Spectrum Sensor which nullifies the need of the radioactive ionization sensor as you know, it detects smoke produced by flaming fires which burn at a fast rate so, if the ionized air is disrupted by smoke, it triggers the alarm. The photoelectric sensors is used to detect any smouldering fires that uses a light beam which, normally does not hit the sensor, but when smoke scatters the light particles, it will hit the sensor, therefore triggering the alarms – this method is used to detect a fire in its early stages, therefore reacting a lot faster. Now, the Split Spectrum Sensor should detect both the flaming fires and the smouldering ones, by adding a blue LED light at a wavelength of 450nm to look for small particles which are an indicator of a rapid, fast burning fire and keeping the usual photoelectric sensor to detect smouldering fires. To make sure it doesn’t repeat the mistakes of its predecessor annoying false alarms, the new sensor is isolated from any outside light and the encasing is designed to only allow smoke in and nothing else this worked just fine since the second generation of Nest Protect is indeed less prone to false alarms.
