1. INTRODUCTION
SV 279 PRO is an outdoor monitoring station
based on the SVAN 979 Class 1 sound level
meter and SA 279 outdoor microphone kit. The
solution is recommended for short term and
semi-permanent noise measurement in the
environment.
The IP 65-rated case contains a lead-acid
battery the operating time of which can be easily
extended by connecting an external battery or a
solar panel. The intelligent charging unit enables
the use of a solar panel without expensive
controllers or heavy batteries. The case is fitted
with very robust, waterproof connectors (military
standard).
The station provides broad-band results such as
Leq, Max, Min and Peak with all standard
weighting filters together with an incredible time-
history logging feature with two adjustable
logging steps. The broad-band results can be
recorded in three acoustic profiles which enable
parallel measurements with 3 different filters
(e.g. A, C, Z) as well as 3 different detector time
constants (e.g. Fast, Slow, Impulse).
The SA 279 outdoor kit protects the SVAN 979
preamplifier and microphone from weather
conditions. The SA 279 is made of lightweight
materials and can be easily installed on a mast
with standard mounting threads.
SVAN 979 can be easily removed from the station case and used as a hand-held
sound level meter. The monitoring station uses a 3G modem for remote
communication with the Internet. SvanNET, a relay server, supports the connection
between PC and station. Thanks to SvanNET users may use a mobile phone or
tablet to check the status of the monitoring station.
FEATURES:
•SV 279 PRO is a portable monitoring station housed in an IP67 waterproof
case dedicated for periodic outdoor measurements.
•The station is based on the SVAN 979 which can be easily removed from the
case and used as a hand-held sound level meter.
•Class 1 noise measurements are performed over a very wide dynamic range
over 110 dB from 3 Hz up to 20 kHz.
•The Time history of results such as Leq, Max, Min and Peak is saved on a
micro SD-card.

The monitoring station case is equipped with an
air pressure compensation valve that enables the
user to open the case easily if the internal
pressure is lower than the atmospheric one.
Any remaining moisture after closing the lid will be
absorbed by the silica gel bags (optional
accessory).
Note: The valve must be closed when the
station is used outdoors, otherwise the case is not
sealed against moisture.
The valve should be released if opening the top lid
is problematic.
The station case is equipped with three Souriau UTO type connectors for:
•input signals from the microphone
(INPUT).
•external Interface for SP 274 meteo
module or alarm lamp.
•powering station and charging the internal
battery (DC SUPPLY).

Monitoring Station SV 279 PRO 10
To connect the cable to the case socket, start by
lining up the key on the plug and socket, then lock
the connector by turning the ring clockwise (only
the ring close to the socket will rotate).
To disconnect cables, push the connector towards
the station and turn it counter-clockwise. New
connectors require more force so using a closed
hand is more effective than using only fingers.
The station is equipped with a Lead-Acid
rechargeable battery (17Ah, 12V), located in the
bottom of the case.
The battery can be used in any chosen position
without the risk of leakage. The battery has a
pressure relief valves that allows safe dispersal of
any excess pressure inside the cell (VRLA).
Battery capacity may vary depending on the
ambient temperature.
The safety fuse is located on the left side of the
connection plate.
Note: Do not remove the battery from the case! This operation must be done
only by the authorised service.
Note: Battery is not restricted for air, surface and water transport. Classified
as non-hazardous material (IATA/ICAO Special Provision A67, DOT-CFR Title 49
parts 171-189, IMDG amendment 27).
Note: It is necessary to charge the battery after any total discharge, otherwise
the battery may lose its capacity.
Note: It is recommended to charge the battery at least every 6 months in the
case of the station not being used.

Monitoring Station SV 279 PRO 11
The case cover is equipped with an antenna.
2.1.2. SD 270 PRO Controller
The SV 279 PRO monitoring station is equipped
with the SD 270 PRO controller thatintegrates and
controls all system modules and is responsible for
the powering of all elements and communication
between the following elements of the monitoring
station:
•SVAN 979 instrument,
•3G modem
and optionally
•SP 274 meteo module, alarm lamp etc.
A very important task of the controller is power distribution - it provides appropriate DC
power to every element of the system (managing external power sources such as a
power supply SB 270 or optional solar panel or external battery).
The next key task of the controller is the integration of the whole system –examining
the communication, state and condition of every module of the system and the
immediate indication of all problems on the control panel by means of several LEDs or
remotely using 3G Internet connection.
The controller also analyses the temperature condition inside the monitoring station
case. If the internal temperature is higher than 50oC, the controller will switch off
internal battery charging. If the temperature further increases over 65oC, the controller
will switch off the monitoring station. The station will be also switched off, if the internal
temperature falls below -30oC.
A mini USB connector is positioned on the front panel of the controller and is
designated to the controller firmware upgrade.
Note: The mini USB connector on the controller panel doesn’t provide any
measurement or setup data exchange with the PC. Such data exchange is carried out
via the USB Device 1.1 interface of the SVAN 979 (USB socket).

Monitoring Station SV 279 PRO 12
Note: Communication of controller or SVAN 979 with a PC requires installation
of the USB drivers on your PC. USB driver for Svantek devices are available on
http://svantek.com/support-drivers-software.html
Note: Before starting upgrading be sure that your SvanPC++ software is Off! If
not, please Exit it before starting any upgrading.
To upgrade the firmware of the controller go through the next steps:
1. Switch off SVAN 979 and wait until all LEDs are off.
2. Connect the controller to the PC with SC 56 cable.
3. Run the “file2usb.exe”file on the connected PC. The BAT 1 LED will start
flashing a green colour.
4. After “Success” is registered on the PC, disconnect the SC 56 cable.
Note: In case of any problems with the upgrade, switch off SVAN 979 and wait
until all LEDs are off, then extract the controller from the case and repeat steps from 2
to 4.
2.1.3. SP 270 - 3G modem
The 3G modem (SP 270) provides fast data
transfer over the Internet to a PC with standard
Internet connectivity. A 3G modem type
“GeMalto®EHS6 Terminal”is used.
GeMalto®EHS6 Terminal uses mini-SIM cards
25mm x15mm with Internet Access. The SIMslot
accepts 1.8V and 3V SIM cards in accordance
with GSM 11.12 Phase 2.
Note: See also GeMalto®EHS6 Terminal user manual.
The SIM-card is inserted with the circuit side
facing left in the slot pushing it until it snaps hold.

The SIM-card can be removed from the card slot
by using a pen or other flat object. Press on the
card until it snaps out. Use tweezers to remove
the SIM-card from the slot.
If settings of SVAN 979 in “Wireless Transfer” menu are correct then once you insert a
SIM card in the modem slot the remote communication settings of the modem are
automatically adjusted to connect to the SvanNET server. In some cases APN should
be provided.
Note: Be sure that the PIN of the SIM card is off!
2.1.4. SVAN 979 - Sound and Vibration Analyser
SVAN 979 is a Class 1 Sound & Vibration level meter as well as a real time 1/1 or 1/3
octave analyser and is a core of the SV 279 PRO system. Its role is to make
measurements and save results in files, as well as to control data transfer via modem
to the SvanNET server or directly to thePC. The measurement results can be analysed
later with the use of the SvanPC++ software.
SVAN 979 can be easily removed from the case and used as an independent hand-
held sound or vibration level meter/analyser, not as an integral part of the SV 279 PRO
system.
Main important features of SVAN 979 as a part of SV 279 PRO system:
•Three user configurable profiles allow parallel
measurements with independently defined
frequency filters and RMS detector time
constants. Each profile provides a significant
number of results (like Spl,Leq, Sel, Lden,
LEPd, Ltm3, Ltm5, LN%,LR15,LR60,Ovl,
Peak,Max and Min).
•Advanced time history logging for each profile
provides complete information about the
measured signal using the SD-card fitted in
the bottom of the meter and can be
downloaded to any PC using SvanNET or
SvanPC++ software.
•All required weighting filters: A, B, C, Zare
available with this instrument.
•SVAN 979 can, simultaneously to the meter
mode, perform real time 1/1 Octave or
optional 1/3 Octave analysis including
calculations of statistical levels.

Monitoring Station SV 279 PRO 14
Note: See also SVAN 979 user manual.
SVAN 979, when it works with the monitoring
station, is powered from an external power
supply via the 6-24Vsocket.
Data transfer to the modem is via a USB Host
socket, the serial interface working with speeds
up to 2 Mbit/s.
Other instrument sockets are not used in the
SV 279 PRO system.

Note: For safety reasons, it is recommended to remove the internal batteries
from the instrument when it is inside of the monitoring station case.
To extract the batteries
the user should switch
off the instrument,
unscrew the bolt, take
off the black bottom
cover of the instrument
and slide the battery
tubes out.
The user should then fix the bottom cover back on.
SVAN 979 is delivered with 8GB micro SD-card.
The user may exchange it for a 32GB card, but before insertion the card must be
formatted as FAT32.
The micro-SD Memory Card is in the slot under
the bottom cover and can be accessed after the
bottom cover is removed.
To extract the card from the card-slot, the user
should push on the card and then pull it out of the
slot.
There are three important settings, which should be assured in the instrument as a part
of the monitoring station:

Monitoring Station SV 279 PRO 15
1. The Compensation Filter should be set to
SA279 (90o)or SA279 (0o)filter (path:
<Menu> / Measurement /
Compensation Filter). Both filters are
dedicated for the permanent outdoor
monitoring application. The characteristics of
the outdoor filters depend on the application:
environmental (the acoustic signal is parallel
to the microphone’s grid) or airport (the
acoustic signal is perpendicular to the
microphone’s grid). The frequency
characteristic of the designed filters is given
in App. C to the SVAN 979 manual.
2. Network should be set to GPRS (path:
<Menu> / Instrument / Wireless Connection /
Network).
3. RS232 should be switched on in the
Communication Ports window (path:
<Menu> / Instrument /
Communication Ports).
Other settings depend on measurement and transmission type.
All measurement, instrument and transmission settings can be set up via SVAN 979
user interface, or remotely via the server SvanNET or SvanPC++ program.

Monitoring Station SV 279 PRO 16
2.1.5. SB 270 - external power supply with AC/DC converter
SB 270 is waterproof Single Output Switching Power
Supply which is characterised by:
•Universal AC input / Full range (90 ~ 264VAC)
•Protections: Short circuit / Over load / Over
voltage
•Fully encapsulated with IP65 level
•Fully isolated plastic case

Monitoring Station SV 279 PRO 17
2.1.6. SA 279 - outdoor microphone protection kit
The SA 279 outdoor kit protects the SVAN 979
preamplifier and microphone from weather
conditions. The use of the outdoor kit requires an
extension cable between the instrument and its
preamplifier (SC 279). The SA 279 is made of
lightweight materials and is easy to install on a tripod.
This solution is recommended for short term and
semi-permanent noise measurements in the
environment.
The outdoor microphone kit has ¾” screw on its
bottom which enables the use of standard tripods or
other user specific mountings. Technical data such
as direct and frequency characteristics associated
with the microphone are included in the SVAN 979
user manual.
As an option the user may use desiccator - Silikogel.
The desiccator absorbs moisture commonly
contained in the air. The desiccator should be
regenerated after some period of use, when it
changes colour to red, by drying it for 3 hours in a
temperature of 150°C. The colour of the silica gel is
visible through the hole on the top of the dessicator.
Note: See also SA 279 Assembly Guide to
learn how to assemble and disassemble the
microphone’s outdoor protection.
Note: The correct connection of themicrophone is not signalled by thecontroller
therefore it is recommended to perform a test measurement each time the station is
turned on.

Monitoring Station SV 279 PRO 18
2.2. Optional accessories for SV 279 PRO system
2.2.1. SV 33A –Class 1 Acoustic Calibrator
For result verification purposes, most norms and
standards impose the requirement to calibrate the
measurement channel before and after each
measurement or measurement session.
An acoustic calibrator is a device which produces an
acoustic pressure of defined level and frequency.
SV 33AAcoustic Calibrator produces an acoustic
pressure of defined level 114 dB at a frequency of 1
kHz.
2.2.2. SB 272 - External rechargeable battery
SB 272 is an external source of DC power for the
monitoring station. SB 272 includes a Lead-Acid
rechargeable battery (33 Ah, 12 V) and is dedicated
for outdoor use because of its waterproof case. The
battery capacity enables up to three times longer
operating time of the monitoring station in
comparison to the station’s internal 17 Ah battery.
The SB 272 set includes the SB 273 indoor charger
and a cable for connection between SB 272 and the
monitoring station case.
SB 272 has one connector for charging and for power supply and therefore cannot be
used as a power supply for the monitoring station and at the same time be charged
itself (as the internal station battery with solar panel or external power supply).
Note: SB 272 cannot be charged by the monitoring station SB 270 power
supply!
Note: Battery is not restricted for air, surface and water transport. Classified as
non-hazardous material (IATA/ICAO Special Provision A67, DOT-CFR Title 49
parts 171-189, IMDG amendment 27).
Note: It is necessary to charge the battery pack after discharge, otherwise the
battery may lose its capacity.
Note: It is recommended to charge the battery at least every 6 months in the
case of the station not being used.

Monitoring Station SV 279 PRO 19
2.2.3. SB 271 - Solar panel
The SB 271 solar panel (40 Watt, 12 V) extends the
working time of the monitoring station. The size and
weight of the panel enables easy transportationin the
dedicated carrying bag.
The SB 271 solar panel does not require additional
batteries or external controllers.
The mounting system enables mounting of the
SB 271 solar panel above the monitoring case which
provides a natural shade that protects the station
from overheating.
The SB 271 is equipped with a military standard
connector cable for direct connection to the
monitoring station.
2.2.4. SP 274 - meteo module
SP 274 is a Vaisala Weather Transmitter WXTxx
type meteo module used with the SV 279 PRO
monitoring station.
It measures the 6 most essential weather parameters
(barometric pressure, humidity, precipitation,
temperature, wind speed and direction) and also rain
and hail intensity. It has low power consumption
(working also with solar panels), iscompact and light-
weight, has no moving parts,has internal heating and
USB connection and can be easily installed with a
one-bolt mounting method.
SP 274 has an automatic control circuit that switches
the heating on at low temperatures.
Five measurement weather parameters (barometric
pressure, humidity, temperature, wind speed and
direction) are transferred fromSP 274 via USB to the
monitoring station controller every second.
Precipitation is measured and 3 values for rain and
hail (intensity, accumulation and duration) are
transferred, every 10 seconds, only when it is raining
or hailing These parameters are not averaged but
integrated.
Note: See also Vaisala WXT520 User Guide.

Monitoring Station SV 279 PRO 20
The controller then transfers the weather parameters
to SVAN 979, which saves them in a logger file as a
history if the Meteo position is On in the
Logger Results list (path: <Menu> / Measurement /
Logging / Logger Results).
SVAN 979 also integrates weather parameters for
the period, defined by the parameter
Integration Period in SVAN 979 (path: <Menu> /
Measurement / General Settings) and then saves
them as Summary Results if the Meteo position is
On in the Summary Results list (path: <Menu> /
Measurement / Logging / Summary Results).
