- 【3 Alert Modes: Chime / Alarm /Mute】Chime Mode plays your chosen ringtone once when the door opens, with the alert length depending on the selected ringtone. Alarm Mode continuously repeats the selected ringtone until you press any left-side button on the receiver to stop it, while Mute Mode provides silent LED flashing alerts. Set a different ringtone for each sensor to easily identify which door has been opened.
- 【Door Alarms When Opened】When you’re resting at home or busy with chores, a simple one-time chime can be easy to miss if your child opens a bedroom door or a loved one with dementia tries to leave the house. Alarm Mode keeps the receiver sounding continuously, so you don’t have to worry about missing the alert, helping you stay aware of your family’s movement and enjoy greater peace of mind.
- 【Business Entry Chime】When employees are busy restocking in the back, Chime Mode plays your selected ringtone once when a customer opens the door, such as a clear “ding-dong” to welcome visitors and alert staff in time. Even when the entrance is unattended, employees can hear the chime and come forward quickly, making every guest feel warmly welcomed and thoughtfully served.
- 【Home Security】While you sleep at night, this alarm instantly sounds a 110 dB siren if a door or window is forced open, or if someone opens a door to a restricted area such as a storage room or stockroom without authorization, alerting you right away to possible unwanted entry. It gives you valuable time to respond, so you can check the situation and act quickly to help protect your family and property.
- 【IP55 Waterproof Sensor】The IP55 waterproof sensor is suitable for indoor and outdoor use and can withstand light rain or splashes. Keep the sensor and magnet within 1.18 inches for proper detection. Do not mount it on metal door frames, as this may cause magnetic field interference, affect performance, and lead to false alerts.
- 【Long Battery Life】Designed with low power consumption, this door sensor is lab tested for over 30,000 door open and close triggers, helping reduce the need for frequent battery replacement. The sensing distance stays stable and does not shrink as the battery level drops. With no on/off switch on the sensor, there’s no need to worry about children accidentally turning it off.
- 【Custom Chimes & Volume Levels】Choose from 30 ringtones, including chimes, alarm tones, and voice prompts, for daily reminders or safety needs. With 5 volume levels from silent 0dB to up to 110dB, the receiver is loud enough to hear across your space. For large or multi-story homes, place the receiver where alerts matter most to stay aware of door activity.
- 【2 Installation Methods】Use the included 3M adhesive pad to mount the sensor on most doors or windows without tools, screws, drilling, or wall damage — ideal for renters. For a firmer setup, secure the sensor back cover with screws. Not recommended for metal doors, as they may affect performance.
- 【After-Sales Service】Video tutorials are available in the user manual and on the product page to help you get started. If you have any questions or run into any issues while using the product, please contact us through the order channel, and we will assist you as soon as possible.
