TRI-GARD 510 AUDIO DETECTOR
The Tri-Gard is a patented passive sonic glassbreak detector designed
to detect the sound signals produced by the breaking of most types of
uncovered glass, including 1/8" and 1/4" plate glass and 1/4" wired
glass.
The Tri-Gard features two individual stages of frequency filtering, pro-
viding excellent rejection of audio signals out of the glassbreak spec-
trum, and patented signal processing which analyzes all three sound
dimensions- “Amplitude” (loudness), “Frequency” (tone, pitch) and
the “Rate of Change” of the amplitude and/or frequency.
The maximum range is up to 60 feet from the unit in an open area -
hard acoustical environment. The IEI-510 is self adjusting to compen-
sate for background noise and/or rising audio signals.
The TRI-GARD utilizes 3 LED'S to provide a constant visual readout.
The green LED indicates power on normal status. The amber LED
shows a reading of both amplitude and frequency. The red LED shows
an alarm condition. The red LED can either automatically reset or can
latch-in requiring the unit to be reset by power interruption. The unit
will still detect with the LED on.
