Because of its nature, the ionization sensor tends to be more sensitive at detecting small particles, therefore more often triggering false alarms. The First Alert 2 in 1 steered clear of the ionization sensor and only went for the photoelectric type. The photoelectric sensor is better suited at detecting larger particles usually from smouldering fires, that don’t erupt immediately into flames by using a light beam inside the detector which doesn’t directly hit the sensor, but will do so in case smoke enters the device and forces the light towards the sensor. Besides the smoke detecting sensor, the First Alert 2 in 1 also has a Carbon Monoxide Electrochemical sensor which has the role of detecting any rising levels of CO inside the room and triggering the alarm when the concentration crosses the safety levels there will be both visual and audible signals – up to 85dB at around 10 feet. If the sensor detects increasing levels of Carbon Monoxide, the CO LED will flash a red colour and the audible alarms will have the following pattern: four beeps, then pause, four beeps and then pause. Otherwise, if the sensor detects smoke in the room, the Power/Smoke LED will flash a red colour, while the audible alarm will beep three times, pause and again three beeps and pause. 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.
