Upgraded 2-in-1 Door Stop Alarm for Home & Travel, Silver

The door stopper alarm can provide effective security protection when you are sleeping or engaged in other activities. Even if intruders attempt to force the door, they cannot gain entry to your home, apartment, or hotel room when the alarm is activated. The package includes 1 door stopper alarm (9V battery not included).

To install the battery, ensure the on/off switch is in the "off" position. Then, turn the unit over, open the battery compartment, insert one 9V battery, and close the compartment. The gap between the door bottom and the floor should be 1 - 3.5cm.

When the door stopper alarm is in the "on" position, it will trigger an extremely loud 120dB alarm if any pressure is applied to the door. This can help wake or alert the homeowner or renter, deter the intruder, and possibly notify nearby neighbors, providing valuable security protection.

In the "off" position, the door stopper's high-damping rubber bearing can prevent the door from sliding, keeping it in an open position without any loud alarm sound.

The door stopper alarm offers three levels of sensitivity: high, medium, and low. The adjustable sensitivity switch on the side allows you to select the appropriate level. The "H" setting is the most sensitive, while the "L" setting is the least sensitive. If the alarm sound gradually becomes smaller, it may be time to replace the battery.

The door stopper alarm is easy to use and requires no installation or wiring. Simply place it behind any door, whether at home, in a hotel, or elsewhere. It is powered by a 9V battery (not included) and is highly portable, weighing only about 120g. The loud 120dB alarm can provide peace of mind when traveling or living/working alone, making it suitable for use in bedrooms, hotels, apartments, dorm rooms, and front doors.
