SanJie 3 Sensors +2 Receiver Wireless Door Chime with 26 Tones

Magnetic door sensors trigger a chime or alarm as soon as a door opens, giving you an audible cue for home or business entry points. Choose from 26 tones and five volume levels, including mute. Need to tell which entrance was opened? Each sensor can be assigned a different chime.

What matters most

This wireless door chime is designed to alert you when a monitored door or window opens. At home, that cue can help caregivers stay aware of a young child’s room or an older family member’s exit. In a shop, it can announce that someone has entered while you’re occupied elsewhere. Compared with a basic push-button doorbell, its magnetic sensors respond to opening doors and can identify different monitored entrances with distinct tones.

You can select from 26 sounds and adjust the volume across five levels, with a mute setting available when you don’t want an audible alert. The receiver also has LED indicators and a memory function that retains the previous tone after it is unplugged and reconnected. Its alarm output is listed at up to 110 dB, giving you options for different spaces and listening preferences. Buyers often praise the sound choices, volume adjustment, and straightforward setup, feedback on the alarm’s consistency is mixed, so follow the pairing and sensor-placement guidance during installation.

Getting the most from it

The receiver plugs into an outlet, while the magnetic sensors attach to a door or window with the supplied adhesive tape or screws. Position each sensor and its magnet with their triangles aligned and less than 0.4 inches apart. This close alignment helps the sensor register the door’s movement. For a practical home setup, place sensors on the entrances you want to monitor and assign a distinct tone to each one. When a child’s bedroom door or an exterior door opens, the sound can help you recognize which entry point was triggered without checking each sensor individually.

The system can be paired with additional magnetic sensors, and each can use a different ringtone. To change a sound, use the arrow buttons to select a tone, then press and hold the center SET button near the door magnet for 6–8 seconds, repeat the pairing process for other sensors. Walls and metal obstacles can affect wireless signal strength, so place the receiver where it can communicate with the monitored entry points. The light stays on while the unit is chiming, and the chime stops after sounding even if the door remains open.

Practical tips

Choose tones that are easy to distinguish if you’re monitoring multiple doors, then set a volume that suits the room and the people nearby. For a small retail space, a clear entry chime can alert staff when a visitor comes in, at home, a quieter tone may work better for routine monitoring. If a sensor becomes unreliable, check that its magnet is aligned and within the recommended spacing. Replacing a sensor battery requires pairing the chime again, so complete that step after a battery change.

Final verdict

SanJie’s wireless door chime is a practical choice for households and small businesses that want an alert when a monitored door or window opens. Its combination of selectable tones, adjustable volume, mute, and sensor-specific chimes makes it useful for distinguishing entry points as well as hearing that one has opened. For monitoring a child’s room, a household entrance, or a customer-facing door, it offers a flexible alternative to a single-tone entry bell.
