Hurricane windows & glass break sensors

[Rick DeBay]

While helping a neighbor put up plywood, her brother was telling me about his
PGT hurricane windows (which I also have). He said that a few years ago some
kids tried to break in, and had to smash the window a dozens of times in order
to be able to slit the plastic inner liner and reach in to the door latch. His
glass break sensor never went off.
I assume this is because the newer alarms are tuned to avoid false positives,
and only react to the signature of a normal glass window.
Have any companies recorded the sound of an impact-glass window breaking? If
so, I'd like to get their sensors.

Thanks, Rick DeBay

P.S. I might not reply for a few weeks, for obvious reasons.

Which sensor did he have (manufacturer and model)??

looks like it is going to hit Florida worse than Frances - Good luck
to you guys there, we missed it here in Nassau, maybe 30mph max with
alot of rain, northern Bahamas is still getting it, Grand Bahama was
still devestated from Frances with lack of food and water, and now
this one has been battering them for 16+ hours, and quite a few of
them being 100mph winds, along with a ton of rain, aiport is under
water again, and most of the island is under water again... if you are
far enough away from it like we were, 150miles to the south, then you
will be ok, but it goes out 200miles to the north with 60+ mph winds!

Anyway, on to those storm windows, I wouldnt know of any glass breaks
that will work with them, Id suggest a contact for sure, you can get
them premade with contacts in them already, we had ordered some from
Canada actually for high end clients like this, also motion sensors,
or beams across the inside, or yard beams. Arent they basically
plastic, thats why I imagine if you made a GB to detect that breakage
it would false too much? Anyway post it if you find one..

Thanks. It made a mess of the east coast and other places. This is the
fourth hurricane in a month to hit the state. We were fortunate again. I
saw a few places that were damaged, including a transmission shop on Cortez
Rd in Bradenton. They had a huge billboard in front mounted to four phone
pole size wooden posts, each about 25 feet high. The wind snapped the
posts, toppling the heavy sign directly onto a nice car parked in the lot.
The car is totaled.

Other than that and a few trees down I didn't see much wreckage in my area.



I'm not certain but I think they're some form of tempered glass. One thing
is for sure. They don't break when you punch or kick them. Some sales
droid told us they have to stand up to an 8-foot long two by four traveling
60 mph or some such thing. The demo included him jumping up and down on a
sample which did not break. I gave it a snap kick and it didn't even scuff.
Then again, my snap kick is a little rusty. :^)

Two sheets of thick, tempered glass sandwiching a thick plastic liner.
Large missle impact test:
9lb 2x4 at 34mph, one on center and one near edge.
Cyclic pressure test:
+70PSF to -70PSF for 9,000 cycles.
Static load:
165 mph wind.

You can break in if you have enough time. Repeated bashing will reveal the
plastic, which you can then slit with a big knife.
If anybody knows anyone who makes sensors, I'm sure PGT would love to hear from
you.

Power went out Saturday night at 8:30PM (last time it went out at 2PM, after the
first puny band). This time it came back on within 24hrs.

A new neighbor designs/installs standby generator systems. I've already started
the process to get some propane tanks installed for the block. Next time we'll
have power for weeks:

Properly installed, they won't even look "ugly"...

Do they have to be wired or can they be wireless? If they're wired, how do you
protect a glass door? Or should I just let the installer deal with it? And how
hard of a thump does it take to activate?
