Use this DOOR STOP to block a door from being opened. If anyone tries to open the door, the 120db alarm will sound. Alarm shuts off when pressure is released from door stop plate. The alarm is pressure sensitive and also works as a door jam.

There is also a movement sensor with adjustable sensitivity to activate the alarm if tampered with. An on/off switch allows the alarm to be turned off so that it doesn't go off in your luggage. Uses one 9-volt battery.
