TRI-GARD 555LS/557LS SIGNATURE SERIES™
audio glassbreak detectors employ state-of-the-art Advanced
Signature Analysis ™ algorithms to sample four bands of audio
instead of one or two like most other detectors. Digital Signal
Processing (DSP) is used to continuously sample and analyze
the sound. Within milliseconds after an audio "event" begins,
the microprocessor starts crunching data. Approximately 1200
comparisons and decisions are made before an event is reject-
ed or confirmed about 0.3 seconds later. Eight glassbreak sig-
nature models and four false alarm models, stored in memory,
are referenced during the confirmation process. The result of
this high-tech performance is more accurate glassbreak detec-
tion and improved false alarm rejection in tough environments.
TRI-GARD 555LS/557LS FEATURES

NOTE 1: The use of mini-blinds, shades, drapes* and sun film* can
reduce the range of the detector by 50%. Since room acoustics and win-
dow coverings can vary considerably, all detector installations should be
checked with the 517 tester.
* Not for sound deadening drapes
* Tested w/ 3M sun film #SH2CLAR (3M is a trademark of 3M Company)
