The X-Sense XS03-WX smoke alarm has a photoelectric sensor that uses a light source positioned at a specific angle. If there is smoke in a room, the smoke will agitate and scatter the light in the alarm’s chamber.

The detector will initiate an alarm sequence and alert you of the presence of a fire. You will get information about the presence of smoke in your house via the colored LED indicator and a beeping buzzer.

The buzzer will have constant short beeps, and the LED will flash RED once every second. If you install the alarm in a Wi-Fi network, you will get an instant app push notification to allow you to respond.

They are also loud with alarms of up to 85 decibels, and their prices from the official manufacturer are the same. The difference between the two is that you get a technically advanced version when you go for the X-Sense XS03-WX.

Although you can connect both devices to the internet, the XS03-iWX allows you to connect similar detectors via the SBS10 base station to create a fire safety network. If one alarm goes off, the rest will also go off.
