Door Chime, Know Which Door Opened, Home & Business Entry Chime | Door Sensor

About this item

• 【Door Chimes When Door Opens】Use this wireless door chime at home by placing one sensor on each door you want alerts for, such as the front door, bedroom door, or back door. Assign each sensor a number, such as 01 for the front door. When a door opens, the receiver instantly chimes and displays its number, so you know which door opened without checking every entrance.
• 【Door Chime For Business When Entering】Install this door sensor chime at a store, office, or café entrance. This door entry chime gives a clear ding-dong when someone enters, welcoming customers and alerting staff at once. Even if no one is by the door, your team will know a visitor has arrived, so staff stocking shelves or working in back can quickly step forward to greet them, ensuring every guest feels welcomed and attended.
• 【Door Alarms When Opened】At night, this door open alarm sounds through the receiver as soon as a child or toddler opens a bedroom door or an elderly family member opens an exit door. It helps you avoid missing nighttime door activity while asleep or in another room, so you can respond sooner and rest with greater peace of mind in a home with kids or elderly family members.
• 【Custom Chime & Volume Levels】This door alarm sensor offers 40 tones and 5 volume levels from mute to 110 dB. Alerts remain clear in larger spaces, and receivers can be placed on different floors. The range reaches up to 600 ft in open areas, with indoor use recommended within 100 ft or 30 m. Expand the system with up to 14 sensors per receiver and up to 20 receivers per sensor.
• 【Long Lasting Battery Life】Featuring an ultra-low-power chip and a replaceable CR2450 battery, the door sensor has been tested through 100,000 activations and can provide up to 2 years of use. For doors that open throughout the day, this means fewer battery changes and less time spent on upkeep.
• 【Easy to Install】This door chime comes pre-paired for quick setup. Plug in the receiver, clean the surface, peel off the adhesive backing, align the sensor horizontally, and press firmly for 5 seconds. No tools, drilling, or wiring are required, making it convenient for renters. The memory function keeps your selected tone after unplugging. Not suitable for metal doors.
