AVANTEK Wireless Doorbell Bundle (D-3B + CB-11), 2 Push Buttons + 3 Plug-in Receivers, Waterproof Chime up to 1300 ft for 2 Doors & Whole Home, 52 Melodies, 5 Volume Levels, LED Flash, No Wi-Fi, Black

“Never miss a visitor again with the AVANTEK Wireless Doorbell Bundle (D-3B + CB-11) — two complete doorbell kits in one box. You get the D-3B kit (1 push button + 2 plug-in receivers) and the CB-11 kit (1 push button + 1 plug-in receiver): 2 weatherproof buttons and 3 plug-in receivers in total, so you can cover two separate doors and hear every ring throughout your whole home. Mount one button at your front door and the other at a back, side, garage, office, classroom, store, or warehouse door. Plug the 3 receivers into outlets on different floors and rooms — kitchen, bedroom, basement, or upstairs — so a chime always reaches you, even rooms or floors away. The D-3B transmits up to 1,300 ft / 400 m and the CB-11 up to 1,000 ft / 300 m in open areas, making this a true long-range wireless doorbell for large or multi-story homes. Both kits offer 52 melodies and 5 adjustable volume levels up to a loud 115 dB, plus a bright LED flash — a great choice as a doorbell for the hard of hearing, the elderly, or noisy rooms. Set a different chime for each button so you instantly know whether it is the front or back door ringing. Built to last outdoors: the push buttons are weatherproof (IP55 dust- and water-resistant) and work from -4°F to 140°F through rain, wind, and cold. They run on long-life lithium batteries (up to 3-year lifespan) with no wiring, no hub, and no Wi-Fi or monthly fees. The Memory Function remembers your last melody and volume after a power outage. Setup takes minutes — fix each transmitter with the included screws, anchors, and adhesive pads, then plug in the receivers. Both the D-3B and CB-11 use the AVANTEK plug-in system and can be expanded with extra AVANTEK RB-1/CR-1 receivers anytime. Bundle includes: D-3B (1 button + 2 receivers), CB-11 (1 button + 1 receiver), mounting hardware, and AVANTEK customer support.”
