Installation reccomendations
 Verify that the beam tower is fully watertight once the cover and end caps
have been correctly filled at the end of the installation.





Use the cable glands supplied on the tower for all cabling must pass through the lower
end cap using the cable glands supplied.
Avoid any type of obstruction between the transmitter and receiver.
Avoid installing the receivers beams in a position where direct sunlight, at the same
angle as the receivers beams, can enter directly into optics especially at sunset and
sunrise
Do not install multiple beams where the transmitter beam can interfere with other
receiver beams. It is always better place either transmitter or receivers back to back.
Do not use switched power supplies which can induce noise on the power supply
voltage which can in turn be amplified by the optical sync electronics creating
unwanted problems.

Introduction
Parvis
is an active infrared beam perimeter intruder detection system for use in any
application where a covert detection is required.
Designed for external use, Parvis can be employed in all ambient conditions thanks to the
thermostatically controlled heating of the beam tower, high specification optical assemblies,
automatic gain control all of which maintain the effectiveness and reliability of the system.
External installation
It is advisable to take into account any trees, hedges or bushes that are near to the proposed
perimeter detection path during the planning stages; these can in the event of strong winds
interfere with the beam.
In the same way grass that is permitted to overgrow can obscure the lower beam.
Hidden kit
As the Parvis detection system is both covert and camouflaged it is possible to add
illumination with or without detection beams.

Assembling the cable pit
The cable pit has two functions; the first is to permit easy connection of all the cable ducting
and conduit and secondly as a hold solid base to mount the beam tower.
Single cable

Use the supplied nuts
and bolts to assemble
the cable pit.
Overlap the right-hand
edge of one side pan
to the left-hand edge of
the next.
Assembled
cable pit,
ensure that the
mounting flange
is uppermost.
5
Positioning the cable pit
Once fully assembled the cable pit is installed ten centimeters below ground level and is
embedded in concrete; once correctly installed it can be covered (with turf or suitable
decking) so that only the IR beam tower is visible .
6
Correcting a incorrectly installed cable pit
The mounting flange has to be level so that the Parvis beam can be installed correctly.
Small adjustments, to make the beam sit perfectly vertically, can be made via inserts in the
top face of the cable pit flange. Underscrewing the insert raises it thus raising the base of the
tower on that side, adjusting the correct inserts will bring the beam back to the vertical.

Installing the base
Ensure that all the cabling to and from the Parvis beam passes through the supplied cable
glands that should be fitted to the base of the tower. Use the central cable gland for the prewired light cabling.

Once the cabling is

Alignment
To obtain the best alignment with the previous and following Parvis, the complete structure
must be rotated, using the narrow section of each column module as a reference, as shown
by the shaded area in the illustration (see figure on page 14).

Initial alignment
Once beam columns have been correctly installed point the transmitter optics towards its
corresponding receiver and vice versa, repeat for all the beam pairs.
This is achieved by manually positioning the lens holder horizontally and vertically using one
of the two screws (which ever is more convenient) to be found above the lens.

Set-up using the test points
It is necessary to put the transmitter PBC into test mode in order to complete the alignment.
Phase 1 Insert into ON position the TEST P SET Link on the main transmitter PCB
Phase 2 Move in OFF the dip switch corresponding to the beam to be aligned.
Phase 3 Connect the Voltmeter, using the cable supplied, to the corresponding receiver test
point, move the transmitter optics slightly in both axes (horizontal and vertical) until
the maximum voltage is obtained. Repeat with receiver optics.
Phase 4 Once the alignement is obtained replace the dip switch in ON
Phase 5 Repeat the above procedure for all beam pairs after which reinsert, into OFF
position the TEST P SET Link.

FUNCTIONAL DESCRIPTION OF THE LEDS
The five LED’s on the MES-9000 PCB give system status indication.
Placing the appropriate link into the ON position can enable these LEDs.
It is good practice, to increase security, to place the jumper (link) into the OFF position, once
the beams have been set-up.
LED MASK
Indicates BEAM MASKING. The MASK will light or flash if an extraneous
modulated IR source greater than that of the transmitter is detected by
receiver electronics. If the ANTIMASK link is in the ON position an alarm
condition will be generated when such IR source is detected.
N.B.: the LED should be OFF in the quiescent condition. If it is either on
or flashing check the TX beam set-up.
LOW SIG LED
Low signal (ENVIROMENT DISQUALIFICATION). When the LOW
SIG. led lights up, this indicates the presence of INTENSE FOG. In the
case of intense fog, before the missing signal alarm conditions are
triggered, the LOW SIG led lights up and the Enviroment Disqualification
output signal will be on the terminal board (OPEN COLLECTOR).
N.B.: When the LOW Sig jumper is in ON position, and when the OPEN
Disqualification intervenes, the barrier is excluded, returning to normal
function as soon as the fog lifts.
LED ALM
Alarm confirmation LED. Normally OFF indicates and alarm when lit.
The condition on the SANDOR is dependent how the links are set on the
RX P.C.B the delay (between 50 mSec and 500 mSec) set on the on
target SPEED trim pot.
LED HTR
Confirms that the system heaters are ON. The PARVIS beam are
equipped with automatic electronic thermostatically controlled heaters,
which guarantee an operating temperature within the housing between
17°C e i 22°C.
The Led is normally OFF and ON when the heaters are ON.
POWER
POWER ON LED. The Power on LED is always ON and indicates that
the that the supply voltage to the PCB is correct.
SINC LED
Confirms that synchronism system is ON. The Sinc LED is always
FLASHING and indicates that the synchronism connection is correct.
23
DESCRIPTION OF JUMPER SETTINGS AND
CHARACTERISTICS
The MES 9000 S PCB can be set-up in a number of different configurations that are selected
using the appropriate Links.
LEDS
When this jumper is ON , the leds are activated.
AND 1 + 2
This configuration can be useful when tall grass and small animals are
present .
The function can also be programmed through remote control, by entering
a positive command + 12V on the terminal marked AND on the terminal
board
BEAM OFF 1
The first beam at the bottom can be excluded, while the remaining beams
continue to function .
The function can also be programmed through remote control, by entering
a positive command + 12V on the terminal marked BEAM on the terminal
board
BEAM OFF 1 + 2
The first two beams at the bottom can be excluded, while the remaining
beams continue to function
The function can also be programmed through remote control, by entering
a negative command + 12V on the terminal marked BEAM on the
terminal board
RND DLY ON
Each time the alarm is triggered with a random delay that varies
between 0 and 1 seconds.
This function is used to confuse and deceive any intruder who
wishes to identify the sensor system.
RND DLY OFF
Alarm command output is generated in real time.
TEST P. SET
During the alignment stage, the bridge must be set in ON position in
order to block the transmission sequence so that it will not generate
signals that can disturb the alignment value readings.
On completion of the single beam alignment operation, the bridge
should return to the normal OFF function condition.
24
MASTER ON/OFF: Positioned in ON it gives to the barrier the normal operativity to the
barrier, if placed in OFF enables the “anti-creeping”, the first optic to
activate the alarm must be interrupted for more than 2 seconds.
SYNC ON :
SYNC WIRE ON Environment disqualification with low signal on 2 optics
random
SYNC AUTO ON Environment disqualification with low signal on 1 optic
random
SINC ON :
WIRE Function programmed in wire synchronism (always maintain
in this position).
G.IN
TEMPORARY BLOCK COMMAND ENVISAGED ON THE TERMINAL
BOARD.
The alarm signal may be delayed for a time of about 60 seconds.
This function is achieved providing a input to the terminal “G.IN”.
An impulse sent to the negative will block the barrier alarm output
for a period of about 60 seconds.
This command is used when beams need to be crossed to enter or
exit without triggering the alarms, and without the need for
disconnecting and reconnecting the installation, that requires
bringing the keyboard or keys outside the protected area.
