Expandable Wireless Doorbell - Waterproof Alert System, Starter Kit for Multi-Unit

The Patent-pending sound chip in the 52 Premium Chimes offers the largest premium selection of real ding-dong chimes, ensuring no annoying or "tinny" childish melody ringtones. This product boasts an effective long operating range, with a proven wireless range of over 1000 ft in open areas and the ability to operate through walls and doors, making it suitable for large homes, apartment buildings, offices, or warehouses.

Featuring an ultra-long battery life, the transmitter button includes a long-life battery that can last up to 3 years on low usage, 1-2 years on medium usage, and up to 1 year on high usage, providing convenience and cost-savings. The doorbell system is also weatherproof and waterproof, operating in all weather conditions between -4°F and 140°F.

With 4 volume levels up to 115dB, the doorbell is always loud enough when you need it, and the convenient low-level setting allows for quiet areas. The smart memory function retains the chime and volume settings during power outages, eliminating the need to reconfigure the doorbell settings if it is unplugged.

Available in a variety of vivid color options, including White, Black, Matte Black, Grey, Beige, Blue, Yellow, Red, and Green, the doorbell button ensures that everyone notices your doorbell. The versatile and expandable system allows you to build your own simple alert system, with the ability to add up to 20 additional buttons, receivers, or sensors.

As seen on Business Insider, Fox, ABC, NBC, and CBS News, the 52 Premium Chimes are praised for their build quality and minimalist style. The built-in receiver memory feature retains the doorbell chime/ringtone selection even when the receiver is unplugged or powered off, and the long-range operation can reach over 1000 feet.

The base start kit includes 2 plugin receivers and 2 remote transmitter buttons, along with double-sided stickers, anchors, screws, and an A23 battery. Customers can listen to the 52 different ring tones before making a purchase by downloading the PDF file from the Specification Guide link.
