SECRUI Door Chime M508+D7 – Adjustable Volume, 400 ft Range, 52 Chimes, Easy Install

Designed for homes and small businesses, the SECRUI M508+D7 Door Chime pairs a plug‑in receiver with a compact magnetic door sensor to deliver timely alerts whenever a door or window opens. The setup is quick and the system feels reliable in daily use.

With 52 chimes and five volume levels, you can tailor the sound to your space, from a gentle notification to a more noticeable alert. The memory function keeps your chosen tune after you re-plug the receiver, so you don’t have to reset every time you power it back up.

The wireless range reaches up to 400 ft in open space, giving you flexibility to place the receiver in a different room or on another floor. The magnetic sensor is small and discreet (3.0 x 1.0 x 0.6 inches) and can be mounted with adhesive or screws for a secure, low-profile setup.

• Plug the receiver into a standard outlet and mount the door sensor with adhesive tape or screws.
