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. Some may argue that smoke detectors shouldn’t necessarily have an elegant exterior and that functionality is more important than the design. While it is true that a smoke detector should have its main focus on the reliability factor, it is also a device that will undoubtedly attract some attention since it will be either mounted on the wall or ceiling. So, aesthetics are important and it is nice to see that the newer smart detectors are better looking with each iteration and have taken advantage of different types of LEDs. But, sometimes, a flashy design is overkill and a simple, non intrusive case is the better choice some don’t like a multitude of LEDs to shine from their ceiling. As you may have guessed, the First Alert SCO501CN 3ST indeed features a relatively simple white round case, on the front with a large Test/Silence Weekly button, as well as two LED indicators CO and Smoke and several cut out areas in form of a leaf and underneath it, there’s the speaker. On the lateral side, you’ll be able to identify a small cover which, when removed, will reveal a dedicated space for inserting the two batteries.
