You can silence any of the alarms by pressing the Test/Silence button: if the smoke alarm has been silenced, then it will remain silent for about 15 minutes before reactivating if the smoke has not been cleared; if the CO alarm has been silenced, it will remain silent for up to 4 minutes before reactivating again if the CO levels haven’t decreased. Now, let’s get to the smart part of this smoke/CO detector. There isn’t really a dedicated app for the First Alert Z Wave, but it can be integrated into a smart home environment by using the Samsung SmartThings hub. The whole process is incredibly simple and it requires using the SmartThings app on either your mobile phone or on a tablet and having the First Alert device ready: start the app and afterwards, in My Home, tap Add a Thing and Connect Now; the app will now look for ‘Things’ and as it does so, slide the batteries into the device while holding the Test button wait for the detector to beep and release the button. After it is powered on, the SmartThings app will detect the device it will be called Z Wave Smoke Alarm and you can tap to configure it give the detector a name and select the room where it will be mounted. Note: The First Alert 2 in 1 works with most other smart home hubs from the market, but it is not compatible with WINK. After finishing the process, you can access the device from the app where you can see the percent of battery left, silence the alarm or checking the notifications and you can pair the First Alert 2 in 1 with other smart devices from your network for example, when the alarm gets triggered, you can configure the lights to turn on or activate any available fans. Note: Inside the package, there is the First Alert 2 in one Z Wave smoke and CO detector, two AA batteries, two screws, two nuts and some documents, including a User Guide the device gets a 7 year limited warranty. The advent of the IoT Internet of Things has shown that there’s great potential for connecting all your home devices and creating a single large network to maintain and configure everything using a single hub which is the heart of every smart home. But, while there are some futuristic advantages your whole house can be controlled by a single phone app from anywhere in the world, there are also some disadvantages: while easier to configure, the smart devices tend to rely on more complex functions to properly operate, so they’re more prone to bugs and failures and, because of that, the warranty usually comes with fewer years than on the devices which lack any smart capabilities these devices are also in continuous draft state since the technology still evolves at an unprecedented pace. Even though this isn’t a smart IoT smoke detector, you still can inter connect up to 16 First Alert alarms wirelessly and, since the SCO501CN 3ST also comes with a programmable talking alarm, it deserves a place in this article.
