Weird Glass Break False Alarm: Pretzels

dropped pots and pans are common. 

Im not sure but I would speculate that the barrel itself could make the low frequency noise required and the pretzels could make the higher frequency noise required to trigger the alarm. 

Yes, barking dogs in the same room, action movies on TV, especially  depicting explosions, and back fire noise from automobiles, just to name a few.

Most times I program them to be active in the away mode, but sometimes in both stay and away.

Embarrassing story time: the first time I used an acoustic sensor was in the master bathroom of a very nice house. High ceilings, marble everything- weird acoustics, in other words. I had armed the panel in STAY mode, which left all the glassbreaks on. Nature called, and I chose to answer that call in the nicest bathroom I had ever seen, because why not?

I had a big ol janitor-style key ring with a thousand keys on it hanging from my belt. As soon as my keys hit the marble floor, the glass break falsed, setting off the sirens and scaring the... living daylights out of me. 

Last time I put an acoustic in a marble-lined room, let me tell you. The reason I'm so good at my job is because I have slowly and methodically made every mistake it is possible to make. 

There is a local daycare that installed glassbreaks in the indoor play area.  The variety of FA causing objects in that room is significant.  Toys hitting the floor, thumps, thuds, sudden shrieks, etc.

I helped them decide to reconfigure those glassbreaks so they were no longer part of the 'stay' arming zones and only on 'away' to solve the issue.

Happens all the time at my house. Kids get up early on Saturday morning and they start clanking their chairs on the wood floor, or trying to climb up on the shelves and drop something. BAM, glass break. One of them dropped a bowl of cereal off the table one day, that was fun.

Ive shied away from glassbreaks because of that. Any change in acoustics makes all the work you did setting it up pointless. Then they go and get a yip dog and its even worse.
