Fosmon WaveLink Motion Sensor for Wireless Motion Sensor Door Chime - White - 1 pack

Magnetic Door Sensor / Motion Sensor / Wireless Entry Alert Doorbell / Wireless Door Chime
With your Fosmon WaveLink system installed, this wireless alert solution ensures you never miss anyone entering your space. Designed for both home and business use, the system integrates magnetic door sensors, motion sensor transmitters, and plug-in receivers to provide reliable alerts whenever doors, windows, or monitored areas are triggered.
Magnetic Door or Window Sensor
The magnetic sensor activates when the magnetic strip is separated. It transmits a signal to the plug-in portable receiver (not included in some models) and alerts you with a ringtone every time the door or window is opened.
Motion Sensor Detection
The motion sensor activates when movement occurs within a detection area of up to 16.4 ft (5 m) at a 110° angle. It sends a signal to the receiver and triggers a ringtone alert, making it ideal for monitoring entrances, hallways, or open areas.
Wireless Plug-in Receiver
The receiver plugs into any standard 110V outlet, providing a simple and reliable setup. Once plugged in, it can be paired with multiple transmitters for full coverage.
Unique Ringtones with Volume Levels
Customize your alerts with up to 52–58 unique ringtones and 4–5 volume levels (up to 110dB). Choose a soft chime or a loud alarm depending on your needs, with mute options available on select models.
Built-in LED Indicator
Both transmitters and receivers feature LED indicators that provide visual alerts when triggered, making the system accessible for the hearing impaired.
Easy Installation
Wire-free and simple to install. Use included double-sided tape or mounting hardware (anchors and screws) to secure sensors. Plug in the receiver, pair the devices, and the system is ready to use within minutes.
Versatility & Expandability
The WaveLink system allows pairing of up to 10 transmitters and 10 receivers. Expand coverage across multiple entry points, stairwells, or rooms to suit your needs.
