Hear It From the Kitchen to the Garage With a 1300ft (400m) openair range, this wireless doorbell reaches every room in a large home, store, or workshop. The stable signal resists interference from walls and other devices, so you won't miss a visitor whether you're in the basement or the backyard. You can pair multiple kits together to expand your whole system. Pair different chimes to different buttons to know exactly which door is ringing. | 55 Chimes, 5 Volume Levels, Plus a Mute Mode Pick from 55 classic ringtones to match your style, or set different tones for the front door and back door. Adjust volume across 5 levels up to 110dB loud enough for a busy classroom or a large home. A mute mode silences the chime when you need quiet, and the LED flash still alerts you visually. | Weatherproof Button That Lasts for Years The IP55 dustproof and waterproof button stands up to rain, snow, and summer heat, working from -22F to 158F (-30C to 70C). Powered by a 12V 23A battery with ultra-low power draw, it runs up to 3 years on one battery so you wont need to change the batteries every few months. | Plug In and Go No Wiring Needed Works right out of the box with no wiring or electrician required. Plug the receiver into any outlet, pull the plastic tab from the button to activate the battery, then mount the button with the included double-sided tape or screws. Most setups take under a minute. | Everything You Need Is in the Box Includes 1 plug-in receiver, 2 battery-powered buttons (batteries included), 2 door plates, 4 screws, 1 mini screwdriver, 3 double-sided adhesive stickers, and an English instruction manual. This 2-button + 1-receiver kit lets you place receivers in the living room, kitchen, and garage or use it as a wireless call button for seniors or anyone who needs assistance at home.
