spring loaded plunger door stop
Unfortunately for Jenny it happened around 1 AM when she was asleep and she didnt hear the storm. But the local hotel burglar did hear it and knew how to take advantage of the situation and to get into as many rooms as possible. He already had success in two rooms - the occupants never even knew that he was in their room. So when he got to Jennys room he felt very confident. No lights were on and it should be easy pickings. But when he tried to open the door it hit the lip of the Door Stop Alarm and set off the 120 dB alarm -- which is very loud. Needless to say Jennys room was not burglarized that night and she stayed safe.
The slower or faster the door opened made no difference on the hard surfaces while the slower you opened the door on the carpet the longer it would take to engage because it would slightly slide back before engaging. As for the strength the stronger you forced the door open the quicker on both surfaces the unit jammed the door. I would recommend it for college students; who want to keep unruly friends out of their dorm room while sleeping renters and travelers who are looking for an inexpensive way to stay safe at there home away from home.
