A door stop alarm serves a dual purpose as both an alarm and a door stop. It helps prevent doors from sliding and deters unauthorized entry, offering added protection for your home and during travel. This door stop alarm features three sensitivity levels: High, Medium, and Low. Adjust the setting based on the gap between the door and floor, as well as the flooring type. It is ideal for doors with a gap between 0.6 and 1.2 inches, providing reliable security. The device includes a loud 120-decibel alarm that activates upon detecting unauthorized entry. If someone attempts to open the door, the alarm sounds to alert you, while the door stop physically blocks intrusion. Please note that the alarm volume is not adjustable. Powered by a 9V battery, the door stop alarm can last up to one year under normal usage. For optimal performance, replace the battery when the sound becomes weak or stops. Battery is not included. Designed for convenience, no installation is required. Simply place the alarm behind any inward-opening door.
