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

[Plug and Play Convenience] This door chime comes pre-paired, eliminating the need for wiring or electrician installation. Simply plug the receiver into a socket and affix the door sensor using the provided double-sided adhesive – you're good to go.

[Extended Range Coverage] Boasting a range of up to 1000 feet (300m) in open air and 150m through walls, this system ensures you'll never miss a visitor, whether at home or in your store. Powered by a long-lasting 23A 12V battery included in the package.

[Customizable Features] With 60 different chime options and a 5-level volume range from 0dB to 110dB, you can create a comfortable environment for your family. A silent mode with LED flash is available when you don't want to be disturbed.

[Battery-Saving Sensor] To avoid battery drain during storage and transportation, the sensor is equipped with a power button. If not in use for an extended period, simply turn off the sensor to extend the battery life.

[Dual-Door Differentiation] All receivers will chime when either door is opened, but each door has a distinct tone, so you'll know which one your guests are coming through. If you prefer a one-to-one sensor-receiver setup, follow the "How to clear the frequency and re-pair" instructions.
