SECRUI Door Sensor Chime for Business/Home, Adjustable Volume, Easy Installation, 400ft Range, 52 Chimes - White

Installation is easy with our doorbell system. Simply plug the doorbell receiver into a standard outlet and use the double-sided adhesive tape on the back of the door sensor to attach it to your door or window. Alternatively, you can screw it in place. Just remember to remove the insulating paper before using the sensor.

Our door sensor acts as a 24/7 lifeguard for your family, alerting you when a burglar opens the door and deterring break-ins with an entry alert chime. The chime activates when the magnetic sensor separates.

You can easily customize your experience with adjustable volume control and 52 chime options. Choose from 5 levels of volume ranging from 0-110 dB and select from 52 elegant music options, from the traditional "Ding Dong" to other well-known chimes. Plus, the memory function keeps your selected tune even after re-plugging the device.

With a wide working range of up to 400 ft in an open area, our wireless door open chime ensures that you are alerted immediately whenever a door or window is opened. The magnetic door sensor automatically triggers the receiver when the magnetic strip is separated.

The mini contact sensor is compact and versatile, with the magnetic door sensor measuring 3.0x1.0x0.60 inches and the magnetic strip measuring 1.7x0.6x0.4 inches. This small size allows for easy installation at any indoor location, providing you with a reliable door entry chime/alert system.
