Overview

Meet the AVANTEK CW-21 wireless door bell, built for everyday living with a long range and flexible setup. With a robust 1000 ft (300 m) wireless reach, you can place the receiver in a living room, bedroom, or even another floor and still hear a crisp, reliable chime. The kit includes two transmitters, ideal for monitoring two doors or entry points, with the option to expand coverage using AVANTEK RB-1 or CR-1 plug-in receivers if your space grows. Quick wall mounting, plus all the mounting hardware, makes setup straightforward without any wiring.

Key Benefits and How They Help

• Wire free installation: fix the transmitter on a wall with included screws, anchors, and adhesive pads for a clean setup without wiring.
• Long range and minimal interference: 1,000 ft range helps you stay connected to visitors from different rooms or levels.
• Rich audio and customization: a 1.1 inch stereo speaker delivers clear sound; choose from 52 melodies and 5 volume levels up to 115 dB; assign tones to each transmitter to identify which door rang.
• Durable and weather ready: IP55 rated for dust and water exposure; operates reliably across a broad temperature range from -4 F to 140 F, covering many climates.
• Low maintenance power: the transmitter uses a lithium battery with lengthy lifespan, reducing replacement frequency and upkeep.
• Memory function: last melody and volume are remembered after power outages, so you return to your preferred settings automatically.

Real Life Scenarios

Imagine a multi level home where you want different alerts for front and back doors. Set separate tones for each transmitter and receive a distinct chime on the receiver when the front door or back door is pressed. In busy households, a clear chime coupled with the LED indicator can help family members notice a visitor even from quieter rooms.

In all seasons, the CW-21 provides a dependable notification system. The visual LED flash can complement the audible alert, helping you respond quickly in bustling mornings or while handling chores in other parts of the house.
