This alarm is sold in packages of two so you can have one for the front door and one for the back door. Simply place the alarm behind any door. If an intruder attempts to open the door the wedge-shaped design will prevent it from opening and activate a 100 dB alarm. The alarm will scare off the would-be intruder and alert you to the attempted entry. This door stopper alarm comes with a movement sensor. When the alarm is turned on you have a 10 second delay before the movemement sensor activates. When traveling just toss this lightweight unit in your luggage. The on / off switch will prevent the unit from accidentally sounding.

This alarm requires 4 AA batteries (2 batteries for each alarm) that are not included. Each door stop measures 6 inches x 1 and seven-eighth inches x 1 and five-eighth inches.

For a single pack of this alarm please see item ID14 or for a door stop alarm with a adjustable movement sensor and streetwise security packaging please see item SDS85.
