I'm looking for a glass break detector (prefer wireless for Concord 4 panel).

The requirements are that it be as close to possible immune from the typical false alarm these devices seem to exhibit from what I've been reading.

Is there any such device?

If you want Concord compatible wireless, then you have no choice but the GE model (wireless devices are specific to the system brand/model).

False trips from glassbreaks are actually fairly rare. You may be confusing them with motions. Basically a glassbreak is a tuned microphone system. Sudden sharp pitched noises in the same range as breaking glass _can_ trip them, but they are not as easy to trip as some make out.

The reason I ask is that I had one in a vacation house, and thunderstorms set it off several times. It was somewhat annoying to deal with the false alarms, so I eventually disconnected it.

I wasn't sure in the intervening years if they had improved. My major concern is thunder storms, since we have them pretty frequently in the summer here.

I would consider wired if there was a more reliable model and/or technology, but wireless would be easier for the location it's in.

We're in central FL. You don't get too many more thunderstorms per capita, and the only recent false trip from a glass break came from someone dropping a cake plate right under the glassbreak with the system armed.

Some of the older models were based on a piezo technology, and could be touchy.
