To install radiators on heating pipes use authorized holders.
2.2. Installing SEL SP – 55/VG vibro-transducers
Glue vibro-transducers SEL SP – 55 /VG using strong waterproof glue,
according its description.
2.3. Installing acoustic radiators
Acoustic radiators should be installed in protected areas (air lines, ventilating
mines, behind false ceilings, etc.).
For minimization of acoustic discomfort the direction of acoustic radiators should
be to places of the most probability of installing pick-up devices.
III. Connecting vibro-transducers and acoustic radiators
The scheme of connection of
vibro-transducers or
acoustic radiators to one
channel:
“
А
” “B”
“
А
”
– full power output on each radiator (1 – 3 radiators).
“B”
– half power output on each radiator (4 – 12 radiators).
It is not allowed
to connect
vibro-transducers and
acoustic radiators to one channel!
Attention!
All channels should be disconnecting galvanic with each other.
The system can be turned in two modes:
-
WORKING – acoustic and vibroacoustic noise generation
mode;
-
SETUP – noise tuning and the system settings mode.
The default settings:
1. Noise is disabled – in all channels;
2. Management of the system – turning on/off the noise
generation:
-
ON – from the front panel;
-
OFF – from the RC.
1.1. Functional characteristics
The system provides:
•
Active protection by wide range acoustic and vibroacoustic
noise for the informational objects from
:
-
microwave systems, including laser microphones,
used for interception of audio information through
glass of windows;
-
stethoscope /contact microphones, used for intercep-
tion of audio information through solid structures
(walls, ceilings, floors, window openings and glass),
gas and water piping;
-
wireless and cable-microphones and devices of
magnetic recording, installed in wall cavities, above
false ceilings, ventilation channels, etc.
•
Optimal parameters of acoustic and vibroacoustic noise for
any channel by setting them up by octave strips, using the
microprocessor and 5-band equalizer;
•
Preservation in RAM all acoustic and vibroacoustic noise pre-
set parameters for each channel;
•
Automatic self-diagnostics system, which will inform the op-
erator about all errors with sound and light alarm;
•
Opportunity of management by the voice activation system
(VOX system) or wire RC.
