Wireless Entry Alarm with 1000ft Range, 60 Chimes and 5 Volume Levels for Business/Store/Home/Office

[Easy Installation] This door chime has been pre-paired before delivery, eliminating the need for wiring or professional installation. Simply plug the receiver into a socket, and use the provided double-sided adhesive to attach the door sensor to the door – you're all set.

[Extended Range] With a range of up to 1000 Feet (300m) in open air, or 150m with walls in between, this system ensures you'll never miss a visitor, whether at home or in your store. The included 23A 12V battery is designed for Ultra-Low-Power consumption, allowing it to last 1-3 years.

[Versatile Features] The door sensor chime offers 60 different chime options and a 5-level volume range from 0dB to 110dB, enabling you to create a comfortable environment for your family. If you prefer a silent notification, the system also features a LED-only flash mode.

[Sensor Power Management] To conserve battery life during storage and transportation, the sensor unit has a power button. If you won't be using the system for an extended period, simply turn off the sensor to extend the battery's lifespan.

[Differentiate Doors] Regardless of which door is opened, all receivers will ring, but each door will have a distinct tone, allowing you to know which entrance your guests are using. If you prefer a one-to-one sensor and receiver setup, refer to the "How to clear the frequency and re-pair" instructions.
