Re: Glass breaks again...

["Robert L. Bass" <robertlbass@xxxxxxxxxxx>]

Hi Larry,

I've used glass break detectors for many years with very good results.  My
installations were mostly in southern New England where summer T-storms are
common though certainly not as common as they are here (Florida).  Visonic's
glass breaks proved very good in terms of catch performance and limited
false alarms.

However, you are right about nearby thunderstorms.  If there's a storm
raging very close by, they will sometimes false.  By "close" I mean directly
overhead.  The Visonics I used did not usually false unless the storm was
very intense.  I would not recommend them in Florida because T-storms are
virtually a daily occurrence during summer here.

Also note that Visonic now has a 1600 series of glass breaks.  Having sold
my alarm company several years ago, I now sell online and Visonic glass
break detectors are among our most popular sensors.  I've sold many hundreds
of FG-1625 units and have had very few trouble reports.
