Title: THIS COULD BE REPLACED WITH A BELL!
Review: As others have already said, I don't know what GE was thinking when they designed this device. It has an operating range of only 20 feet, but has a 30 second delay! That means any intruder has a full 30 seconds to cross the short effective range of the alarm before it alarms! Even at a rate of one foot per second that still leaves a full 10 seconds before it alarms. A human being has to crawl to move that slow and I doubt any intruder will be crawling. As an alarm it's a joke, as an entry door chime, it's OK. However, for about half the price you can get a brass merchant's bell on a nice "s" spring and mount it to your door. It will look a lot nicer too! Don't waste your money on this. I'm sorry I did.
