SanJie Door Chime: 500 ft Range, 3 Sensors + 1 Receiver, 26 Chimes, 5 Volume Levels

Overview

Meet the SanJie Door Chime, a flexible wireless alert system designed to fit homes, stores, and offices. With a 500-foot range, this kit helps you notice door activity wherever you place it, turning quiet spaces into safer, more attentive environments.

Three magnetic door sensors plus one plug-in receiver form a core setup that can be expanded. Each door switch can be paired with its own tone, so you can tell at a glance which door opened without looking. The system includes 26 chime tones and five adjustable volume levels, including a quiet option and a high-volume setting for busy spaces. LED indicators provide a quick visual cue to accompany the audible alert. When power is restored after a temporary outage, the unit remembers your last tune, so you do not have to reconfigure settings.
