63 x 5. 28 inches and the install process follows the same steps: after choosing the rooms in which you’re going to install the Nest Protect at least in every room which has a fuel burning appliance, you need to make sure there is a minimum of 10 feet from any cooking appliance and avoid placing it on a corner you can choose either a wall or the ceiling. Then, you need to take the provided backplate and fix it to the wall/ceiling using the four screws and afterwards, just connect the smoke detector to the backplate using a circular motion if you have the wire powered version, the installing process also includes connecting the device to a power source, but, it’s ideal that this is done by a qualified person, to make sure the installation is made in accordance with the country or state’s regulations. 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. Besides the Split Spectrum sensor, there’s also an Electrochemical carbon monoxide sensor yes, the Nest Protect is also a Carbon Monoxide Detector which detects the CO concentration level inside the room and, if it’s beyond safe levels, it triggers the alarm CO detectors usually last about 6 7 years, but Nest advertises that the sensor on the Protect can last up to 10 years. Furthermore, there’s also a heat sensor so you’ll get notified when the home gets either too cold or too hot, a humidity sensor so it makes it unlikely that the alarm will be triggered when there’s lots of steam, an ambient light sensor so the detector knows when the lights are shut off and it can activate the Pathlight feature or the Nightly Promise – the LED will be green if everything is fine, otherwise, it will become yellow and an occupancy sensor it is used with the Pathlight feature, so it will detect movement and will shine a light on your path during the night – so you don’t stumble on the furniture.

Note: Right now, the water alarm feature only works using the iOS app, but the manufacturer promised that the Android version will also have it available soon. When the device will recognize the specific alarm, it will flash red and you will receive an alert on your phone it can also call you. You can set the device to play a short recorded message of the sound of the alarm when you are called some complained about the low volume. Besides your own phone number, you can set other emergency contacts on the app: it will try to contact you first by pushing a notification, then call you and if you don’t answer/acknowledge the notification alarm, it will contact the other numbers you added to the list. So, in case of smoke, you will get a notification: Smoke alert, Emergency, which will prompt you can take action, by listening to the 5 second recording of the beeping, calling 911 or clicking on the “false alarm” button. The app gives you the numbers of the local authorities to contact in case of an emergency what’s great about this, is the fact that it will direct you to the authorities close to the location of the device, not close to your current location, which I think it’s smart.

Note, Android has blocked users with rooted devices from using the movie rental options. The phone ships with 2. 5 MB of built in memory and a 32 SDmicro card more than enough room to store all your pictures and videos. To sum things up, the Thunderbolt is Verizon's premier phone. It is a better option for you even if you do not have access to the 4G network than the Droid X, merely because the interface from HTC Sence has better functionality than Motorola's MotoBlur. If you are toying with the iPhone, don't.
