Hi All:
I'm trying to find some documentation for some glass break detectors that are built into the wall of a house I'm buying. I'm guessing that these are about 12 years old. They are manufactured by International Electronics, Inc., model IEI-552LS, Audio Glass Break Detector.
They look a bit complicated, and I'd like to figure out how to test/calibrate them.
Anyone heard of these, and can you point me in the direction for documentation?
Thanks, as always,
Rob Houston
