Gabe, not sure, as they did not have many false (or any Real) alarms, but in the case of an intruder, I really wouldn't care what my neighbors thought, Id be glad that they were woke up if necessary though

My sister has an audible alarm inside the air conditioner ductwork, so it really amplifies the sound and is very hard to disconnect if you are a burglar.

My wife worked (for about 3-4 weeks) for an alarm dispatch company. they would field calls from all over the US and Canada. She said that false alarms were very common, and that in a lot of cities, if you have more than 2 false alarms over a certain period (Sorry, I forget how long) that your alarm permit could be revoked by the city you were in.
