Add an instant alarm to ANY door anywhere with the GE 50246 Smart Home Door Stop Alarm. Just place the doorstop next to any door and when the door is opened the pressure sensitive doorstop is triggered and the loud 120-decibel alarm sounds. No wires, no drilling, no cords, just set it down- a rubber base provides traction to keep it in place and a 9volt battery powers it. Great for security while traveling- use in hotels, dorm rooms, or any other temporary rooming situation- even around the house (maybe even outside on a fence?).
