Voice output alarm with location: Choose from up to 17 preset locations. In case of smoke development, a voice alarm sounds in German, e.g. "Warning! Smoke in the dining room. Evacuate." Studies show that children respond faster to human voices than to alarm sounds. (Does not support other languages)
Night mode: set custom times in the app to turn off the green light, allowing you to sleep peacefully without annoying light sources; the night mode does not affect the operation of the alarm
Never miss an alarm: once smoke is detected, you will immediately receive an alarm on your phone. So you are always up to date, no matter where you are. The base station and all networked detectors produce sounds of up to 100 dB, so everyone in your home is alerted to the situation and can immediately leave the building
Increased safety: this talking detector informs you with practical voice messages about important information such as tests, low battery charge, malfunctions, locations, mute the detector and WiFi pairing; Voice messages from the detector contribute to your safety and are especially helpful for people with visual impairment
Home assistant support for individual automations: Own scenarios possible, e.g. Light or smoke detection notifications (manual setup required; no direct device control via Home Assistant)
Convenient device sharing: make life easier by sharing your device with up to 12 family members with the X-Sense Home Security app; so they can effortlessly check alarm status, receive important alerts, and mute the device when needed
App test: Test the detector conveniently via the app on your smartphone. You do not need a ladder to reach the smoke detector, but can check the safety at the touch of a button
