INTRODUCTION.
The PATROL-501 recognizes
particular sound patterns emitted
by glass breakage.
The PATROL-501 provides
complete protection of all known
framed glass types.
The PATROL-501 uses unique
algorithm, based on two-channel
recognition analysis of the
characteristic frequencies and
signal sequence of framed pane
glass breakage.
The LED will light continuously
for 3 seconds and the alarm relay
will be open on alarm.
DESCRIPTION
.
Low-frequency sound occurs upon
the impact on the glass.
High-frequency sound occurs upon
the glass breakage.
HIGH-FREQUENCY LOW-FREQUENCY
SOUND SOUND
For creating an alarm, both a
low-frequency sound of the glass
impact and a high-frequency glass
breakage sound must be registered
within a predetermined time frame.
Since both detector channels
must register the actual glass
breakage, false alarms are
practically excluded.
The program of microcontroller,
based on the mathematical
algorithm, analyzes signals
and detects only the actual
breakage of all standard framed
glass types.
PATROL-501 RELIABILITY.
Due to the unique program and
perfectly adjusted filters the
PATROL-501 provides excellent
protection from false alarms in
extremely harsh environments.
Highly selective sensitivity of the
high frequency channel enables the
PATROL-501 to detect real glass
breakage with high accuracy among
a variety of background noises.
The above features enable the
PATROL-501 to be used in
extremely harsh environments,
such as airports, industrial plants
as well as in the vicinity of noisy
restaurants, bars, etc.
High RFI and EMI immunity allows
the detector to be mounted next to
radio and electromagnetic emission
sources.
