3-Pack 2-in-1 Portable Door Stopper Security Alarm

A Straightforward Breakdown

DOOR STOPPER SECURITY ALARM – ON STATUS When the door stopper alarm is in “on” status, it becomes an immediate security enhancer. Apply pressure to the door, and the alarm triggers instantly, emitting an extremely loud 120dB alarm. This helps awaken or alert homeowners and renters, deters intruders, and even notifies neighbors.

NON-SKID DOOR STOPPER – OFF STATUS In “off” status, the door stopper can serve as a common non-slip rubber base for holding doors in an open position. There is no loud alarm sound, making it a perfect tool for various situations without disturbing anyone.

EASY INSTALLATION Installation is straightforward; no wiring is required. Power is battery-operated (one 9V battery needed, not included). Place it under the door. Ensure the gap between the bottom of the door and the floor is between 10mm (0.38 in) and 35mm (1.35 in). It won’t slide on tile when the door opens. For smooth floors, use the H-type sensitivity vibration-sensing alarm.

3 SENSITIVITY LEVELS Adjust the sensitivity with a switch on the side. The H level is the most sensitive, where even slight vibrations will trigger the alarm. When the alarm sound diminishes, it’s time to replace the battery.

PORTABLE DOOR STOPPER ALARM The package includes three door alarms, each weighing about 120g, making them easy to carry. The alarm is loud at 120dB, providing excellent security. Perfect for travel, bedrooms, hotels, apartments, dorm rooms, and front doors, ensuring peace of mind whether you’re traveling alone or working by yourself.
