Smart Wi-Fi Smoke Detector NOUS E17, with Audible Alarm, TUYA

NOUS E17 is a compact photoelectric smart smoke detector designed for continuous fire hazard monitoring in homes and commercial premises. When smoke is detected, the detector alerts you not only with an audible ≥85 dB alarm and light indicator, but also sends a notification to the “Nous Smart Home” app on your phone.

The compact NOUS E17 takes up little space and can be mounted on the ceiling using the included mounting plate. The detector is powered by a replaceable CR123A 3 V battery with an expected operating life of 3–5 years, so no power wiring needs to be installed to the device.

Integrated 2,4 GHz Wi-Fi connectivity allows the detector to connect directly to your home wireless network and the “Nous Smart Home” app. When smoke is detected, three alert methods are used: an audible alarm, light indication and an app notification. The detector complies with the EN 14604:2005/AC:2008 smoke alarm standard.

Who Is This Product For?

The NOUS E17 smart Wi-Fi smoke detector is suitable for residential and commercial indoor premises where a local smoke warning and the additional option of receiving a notification on a phone are required.

• Home and apartment residents who want to supplement their fire protection with a smart smoke detector.
• Owners of holiday homes and less frequently occupied properties who can benefit from receiving an app notification when the detector is triggered.
• Offices and other commercial premises where a compact photoelectric smoke alarm is required.
• TUYA and NOUS smart home users who want to monitor safety sensors in the same smart home app.

Practical Applications at Home and in Other Premises

• Use the detector in residential areas to provide audible and visual warnings when smoke is detected.
• Install separate detectors on different floors of the building in accordance with applicable fire safety requirements and the manufacturer's installation recommendations.
• In a holiday home or another less frequently occupied property, use the Wi-Fi function to receive remote app notifications.
• In an office or commercial premises, integrate the detector into the “Nous Smart Home” system together with other compatible smart devices.
• Regularly use the test button to check the audible alarm.

Smoke Alerts Not Only in the Premises, but Also on Your Phone

A conventional smoke alarm can only be heard when you are at home or nearby. NOUS E17 supplements its local ≥85 dB alarm with Wi-Fi connectivity and notifications in the “Nous Smart Home” app. This is particularly useful when you are away from home, but the phone notification is an additional feature and does not replace the local audible smoke alarm.

The detector is powered by a separate battery, so no additional power wiring needs to be installed in the premises. Thanks to its compact design and the included mounting plate, it can be neatly installed in a suitable location that complies with the manufacturer's safety requirements.
