Expandable with Additional Transmitters/Receivers
Expand your AVANTEK D-3B wireless doorbell system in seconds with up to 2 transmitters and multiple receivers, thanks to a simple, built-in pairing method. If you’ve purchased this long range doorbell kit, it’s recommended to purchase our D-3G or D-3B doorbell kit (1 transmitter and 2 receiver) or DW-11 plug-in receiver (ASIN: B07BDJTB1R), matching them to meet your specific needs.
With unparalleled 1300 ft wireless range and strong signal penetration, the cordless doorbell will never fail to alert you when someone shows up at the door. Be it a friend or a delivery, you can always rest assured that you'll never miss them again. Feel free to use it for the home, factories, hospitals, offices, apartment blocks, villas and other large areas, knowing that the long operating distance will always get you covered.
The transmitter uses a 230 mAh CR2032 lithium battery which has an ultra long three-year lifespan, freeing you from the hassle of frequent battery purchases. Functional between -4 °F to 140 °F, its tough construction allows this wireless doorbell with 2 receivers to operate in even the harshest weather conditions.
The huge selection of 52 tunes like "We Wish You a Merry Christmas" ensures you will be able to find something you like. In addition, the built-in 40 mm stereo speaker delivers clear and well-balanced sound up to 115 dB, ideal for helping even senior citizens notice when someone rings the bell.
Mother Nature can be fierce. In order to withstand whatever the elements may throw at it, the transmitter has a high waterproof rating of IP55. Even heavy rain will not interrupt the operation of the robust transmitter while stationed outside.
Thanks to its smart memory function, every time you power on the device, it remembers your previous melody and volume level - even after a power outage. This thoughtful feature ensures your personal touch doesn't get removed.
Choose from two simple installation methods: apply the adhesive patch to fix the waterproof doorbell to your wall or use the provided screws to secure it in place. All the required accessories are included in the package for an effortless setup.
