1) GENERAL DESCRIPTION
ERMO 482/... is a microwave system for external protection of the volumetric barrier
type.
Volumetric barrier means the spatial protection obtained by using separate transmitter
and receiver, placed opposite each other, in which one of the three dimensions is
considerably greater than the other two.
This type of systemis able to reveal the presence of a body moving within the sensitive
field set up between transmitter and receiver,
The shape and size of the sensitive field set up between transmitter and receiver in
ERMO 482/... depend on the following factors:
a) Type of antenna used
b) Effective distance between transmitter and receiver
c) Level of sensitivity set up on the receiver
(1) Presence of fixed parts within the sensitive field (1aan walls, fencing, posts, etc.)
e) The type of obstacles, if any
i) Alignment of transmitter and receiver
- Two types of antenna are used:
. 10cm PARABOLIC
. 20cm PARABOLIC'
The 100m PARABOLIC antennae are suitable for the formation of rather wide but
short range fields of protection
The 200m PARABOLIC antenna forms longer fields of protection, but less wide
ranging. (FIG. 1. a-b)

- The effective distance between transmitter and’receiver, depending on the type of
antenna, determines the other two dimensions, due to the fact that the opening angle
of the antennae used remains constant to the variation of the reciprocal distance
between transmitter and receiver. (FIG. 2)
Figure 2 - Variation of the dimension of the sensitive zone on the variation of the
distance
- The level of sensitivity set up on the receiver, according to a particular antenna,
ensures that the microwave barriers can have a sensitivity to more or less intense
disturbance signals. Bear in mind that the weaker signals come from more peripheral
zones of the field, while the more intense signals come from central zones. Thus it is
clear that the regulation of the sensitivity provokes a corresponding variation of the
height and breadth of the field of protection. The length, on the other hand, is
determined exclusively by the distance between transmitter and receiver (FIG 3).
Version 1‘01
Cias Elettronica
Figure 3 - Variation of the dimension of the sensitive zone on the variation of the
sensitivity
- The presence of fixed parts, within the sensitive field, alters the dimensions of the
protection field determined, in theory, by the distance between these and the level of
sensitivity imposed on the receiver.
These dimensions arevalid only when the barrier is installed in a free space .
In all the other cases the obstacles present will provoke distortions of the shape and
alteration of the size of the protection field. ‘
- The nature of the obstacles, eventually present, provokes either a reflection or an
absorption, or a combination of both these phenomena in confrontation with the
electromagnetic energy contained. Therefore, difi‘erent alterations of the protection
field occur depending on the nature of the obstacles (FIG. 4)

- An imperfect alignment between transmitter and receiver provokes, a distortion
of the shape of the protective field which is set up, as well as an obvious reduction of
the signal received. This fact becomes clearly apparent when considering that the
protection field is determined, in the first approximation, by the combination of the
principal radiation lobes of the two antennae, which, if perfectly aligned, will establish
a regular and symmetrical protection field in the two halves of the section, if badly
aligned they will cause asymmetry and a more probable interception of obstacles
(even though apparently outside the sensitive field) (FIG. 5)
FIG. 5 - Sensible zone distorsion for bad alignernent
Bearing these basic considerations in mind, we can state that the general form of the
protection field takes the shape of two trunks of a cone opposed to each other at the
base. The minimum bdimension of the field is the one of the antennae, while the
maximum dimension is determined by all the other factors already examined.
The breadth of the signal received is the vectorial sum of the direct signal and all the
reflected ones. (FIG. 6)

Figure 6 - Vector-ial representation of the signal received
It is easy to see how the introduction of any object into the protected field whether
reflecting or absorbing electromagnetic energy, will provoke an alteration of the
preceding condition, causing a variation in the breadth of the signal received in
proportion to the size of the object introduced and its degree of penetration into the
sensitive fieldlf the object introduced into the protection field is held in movement, it
will provoke a continuous variation of the breadth of the signal received, thus bringing
about a modulating flequency whose breadth is in proportion to the dimensions and
position of the field and of the object introduced, and whose frequency is-proportional
to the speed of movement in the field of the object (FIG. 7)

Electromagnetic energy is radiated from the transmitter in the form of impulses, so that
in the presence of an object in movement within the protection field, as well as the
breadth modulation of the peak of the signal received, we will find a phase modulation
of the impulses detected.
As the fi'equency of the transmitted impulses of electromagnetic energy has 4 difierent
values, it is possible to carry out on the receiver a check of the correspondence of the
frequency received with a sample frequency within the receiver itself.
Thus, we determine a channeling which, as well as offering greater possibilities to
elaborate the signal, makes the system much less vulnerable with regard to any attempt
to neutralise it.

B) Post cover
C) Connector block
D) Connector block cover
6) INSTALLATION
When designing a volumetric barrier protection system, it is first necessary to carry out
an inspection of the site to be protected, in order to note the real operating conditions.
In fact it is necessary to determine:
6. 1) Number of lines to install
6. 2) Length of each line
6. 5) Presence of walls, fences, posts, trees, hedges, other obstacles
6. 6) Breadth of sensitive bands
6. 7) Breadth of the dead zones near the apparatus
6. 8) Height of the apparatus from the ground
6. 9) Supporting poles, their ground fixtures, connector boxes
6. 10) Connections to AC supply
6. 11) Connection of the battery to reserve supply
6. 12) Connections to the elaboration centre
6. 1) Number of lines to install
As the volumetric barrier protection has to be designed within a closed perimeter, as
well as the obvious considerations of the subdivision of the perimeter into a certain
number of lines which take into consideration the operating requirements within the
system, we must remember that it is always best to install an even number of lines,
This is due to the fact that the possxble reciprocal interferences between adjacent lines
are cancelled out if two apparatus with the same name are installed at the vertices of
Cias Elemonica Version 1.01
the polygon obtained by the installation of the various lines: either two transmitters or
two receivers,
Obviously, this can always only takes place when there is an even number of lines.
Ifit is not possible to install an even number of lines, careful considerations should be
given to the possible interferences for the correct choice of the most suitable vertex for
the positioning of the transmitter near the receiver.
The following illustrations show a number of typical cases, with the most appropriate
solution. (FIG. 11)

6. 2) Length of each line
The identification of the length of each line makes it possible to purchase the
appropriate equipment and CIAS supplies, in the same container, a range of four
different capacities and dimensions of the sensitive’ field.
To better understand this subdivision, there follows a table illustrating the various
models, showing the capacity and the type of antenna used. (TAB. 2)

Table 2 - Capacity and antenna used for each model
6. 3) Land conditions
The soul is an enormous obstacle along the entire line, thus ables to exert a notable
influence on the form of intrusion and the response to it. -
To avoid shaded and hypersensitive zones, as much as possflale, particular attention
should be paid to the conditions of the land.
It should be:
a) Fixed
We advise not to install the apparatus where there are vehicle weighbridges, long grass
(over 10 cm), ponds, streams and rivers, and all types of soul where conditions can
change rapidly‘
If this situation is not taken into consideration, there is the risk that the position of the
soul could change rapidly, provoking false alarms. (FIG. 12)
Cias Elettroniea Version l,01
SENSIBLE ZONE ,
Figure 12 - Interference in the sensible zone of high grass
b) Stable
We advise not to install the apparatus where the soul can alter, in the course of the
time, because of natural causes, such as sandy areas, or for man-made reasons, such as
material deposits, where it is possible that the protection zone changes its standard
conditions afier the installation. Ifthis is not taken into consideration, the alteration of
the soul can lead to the creation of dead and hypersensitive zones with, in the first
case, insensitive areas and, in the latter, false alarms. (FIG. 13)

FCC lD: [ST—W001 Version 1.01
Cias Elettronica
c) Smooth
Be sure that the installation takes place along lines with ondulation of less than i 20
cm. If the soul is not perfectly flat, we must bear in mind that there will be zones of
less sensitivity or even dead zones in the depressions, while on the ridges we will find
greater sensitivity or even hypersensitivity, with the result, once again, of possible
insensitive areas or false alarms. (HG. 14)

6. 4) Nature of the soul
Bearing that above in mind, there follows a list of the various types of terrain suitable
for the installation of the apparatus:
a) asphalt
b) concrete
0) beaten earth
d) gravel
e) lawn (with grass no higher than 10 cm)
Cias Elemonica Version 1.01
The following table summarises the possibility, of carrying out a good installation on
various possible soils, also bearing in mind their conditions. (TAB. 3)
Table 3 - Use of barriers in relation to the soil
6. 5) Presence of walls, fences, posts, trees, hedges and various 'obstacles
As we have already mentioned in the general description any obstacle within the
protection field brings about a distortion of the shape and the alteration of the
dimensions.
It should be home in mind that the obstacles in proximity of the protection field can
also provoke distortions of the field itself and, in addition, when these elements are
movable, there is the possibility of false alarms.
In general walls, positioned longitudinally to the line, do not cause great problems, as
they are fixed and poor reflectors. But if they are partially transverse or project
significantly into the protection field, bear in mind that dead zones will be created
behind them and the signal received could be insufficient to guarantee reliable
operation with regard to false alarms. (FIG. 15)

Figure 15 - Formation of dead zone due to the projection of a wall into the sensitive
zone
Fences, as they are generally _made of metal and therefore highly reflective, can
provoke difi'erent problems.
First of all, we should be sure that the fence is well fixed, so that it does not move in
the wind. In case of longitudinal fences, this type of movement could create troubles of
high order. ..
If the fence in question is transverse, it is absolutely essential that it is perfectly
immobile It should be composed of mesh or bars with a maximum space of 3 cm from
one to the other; on the contrary, we could have false alarms.
Mew! fences behind the apparatus can also provoke distortions in the sensitive band,
especially if the mesh is fine (less than 3 cm), and they can cause sudden movement
with the possibility of false alarms (FIG. 16).

Figure 16 - Possible interference due to the presence of metal fence post
Along the line of the protection field, the presence of tubes, posts or similar is
tolerated (lighting standards, for example), provided that their dimensions are not
excessive in proportion to the band of protection.
In such a case a sizeable dead zone would be created and if this zone was very large in
relation to the band of protection, the operation would be unreliable, with the
possibility of false alarms. (FIG. 17)

Trees, hedges and bushes in general require very careful attention, both near and
within that bands of protection. '
These obstacles are variable in dimension and position, and in fact they can be afi'ected
by growth and wind movement.
We, therefore, advise very strongly not to place the protection bands in proximity of
these obstacles. They are tolerable only if thei growth is limited by methodical
maintenance and their movement is checked by suitable containment barriers. (Fig. 18)
Various obstacles may be present along the protection lines, and in the case it is
necessary to take the same precautions as in the previous cases.

6. 7) Length of the dead zones in proximity of the apparatus
The length of the dead zones in proximity of the apparatus depends on the distance of
the apparatus from the ground, the sensitivity set up on the receiver and the type of
antenna used.
6. 8) Height of the apparatus from the ground
Bearing in mind the previous considerations and on the arrangement of the system, it is
necessary to install the apparatus at the right height from the ground.
In average conditions of the system and of taring the height should be 85 cm. (The
measurement is calculated fi‘om the ground to the centre of the apparatus). The
following pictures give a complete idea of the situation for the two types of antenna
used. (FIG. 21-22)

easy to find as they correspond to the extemal dimensions of two inch gas common
pipes.
As already seen in the section on accessories, CIAS is able to supply aluminium
tnmking in 15 cm length, which can be used to build posts of the desired length, as
well as available covers for posts.
The best solution is shown in picture 10.
The posts can be fixed to the ground by inserting them into holes which are then filled
with concrete.
The connector boxes contain the AC supply transformer, with the overall dimensions
of: 85 1‘70 ‘70mm.
For corrent AC supply, this transformer should be placed immediately near the head it
supplies. Picture 10 shows an excellent solution using a coaxial aluminium connector
box at the post made of trunkiugs. This connector box (supplied by CIAS as an
accessory) can house a bipolar switch and a l2V-5,7 Ah battery as well as the
transformer.
Note: The cable which carries the barrier supply fi'om the transformers to the battery
heads must be masked, and the mask must be connected to the ground
6. 10) Connections of the apparatus to the AC supply
The apparatus work with AC supply at a maidmum voltage of 20 V. elf. The
connection between head and transformer should be inferior to 1.5 mmq. ~ - . »
The conductors which connect the transformer to the 220 Vcc must have a section of
2.5 mmq. —
Ifthe AC current is low tension (20 V elf), insulation transformers should be used, 20
V: 20 V of at least 80 VA. (fig. 24)

Cias Elenronica Version 1.01
Figure 24 - Two correct ways to supply the apparatus
Connection between apparatus and transformer is similar to the previous one, the
connection to the 20 V4gn'd should be carried out by hearing in mind its length and the
possibility that each single head of the apparatus may require a maximum current of
1A. In any case, the section should be no less than 1.5 mmq. '
6. 11) Connection of the battery for reserve supply
Within each head of the apparatus, there is a space for the housing of a rechargeable
lead battery of 12 Vcc - 1,9 Ah. The battery is charged by the supplier inside each
head and it is connected to it by a red and black plate with connecting clip fitted within
each single head.
This battery, when there is no grid power, gives apparatus autonomy of over 12 hours.
if greater autonomy is necessary, a reserve supply group should be installed in the
immediate vicinity of each head.
The connection of these groups is carried out at the terminals of the apparatus marked
with the symbols of mass and + 13,8 Vcc.
The size of these groups should bear in mind that the DC absorption of each single
head is 70 mA approx. ,

6. 12) Connection of the apparatus to the elaboration centre
The transmitter head consists of a normally closed contact free from potentials, for
protection during the container opening. '
The connections of these outputs to the elaboration centre should be made with
screend cable with asection of no less than 0.5 mm. Because of long cables circuits in
external environment, troubles can be induced on the cables themselves and so they
can be conduced to the elaboration control panel These troubles can overtake, in case
we use balanced lines, very high values, able to provoke false alarms. Therefore we
advise not to use balanced lines.
If it is necessary to protect the alarm line from cutting and short-circuit we advise to
adopt the following table (FIG. 25).
Figure 25 - Protection of the line fi'om cuts and short circuit by uncoupling relay; this
connection is particularly immune fiom disturbances that can be picked up by the line.

7. ALIGNMENT AND CALIBRATION
The STC 95 was developed by CLAS for aligning and calibrating its intruder sensor
barriers, making it an ideal tool for installers.
The unit is shown in figure 26 on page 28, together with its function specifications.
Figure 27 shows the interconnections between the STC 95 and CIAS barriers.
To set up and test ERMO 482 barriers, proceed as follows:
7.1 - go to the transmitter
- remove the radome unscrewing the allen screws
- connect the AC power supply (19 VAC) to terminals 7-8 (fig 28)
- check that the "MAINS“ led lights (fig, 28)
- connect the faston connectors to the battery, observing the correct

7.2.8 - Repeat the tuning operation with the transmitter head horizontal adjustment.
7.2.9 - Once optimal tuning is obtained, lock horizontal movement of the two heads (RX and TX),
7.2.10 - Slacken the vertical adjustment lock on the receiver (RX) head, and point it upwards.
Shifi it slowly downwards until the maximum reading is obtained on the display (2) and
the led array (3) in the same way as for horizontal adjustment.
7.2.11 - Repeat the vertical adjustment on the TX head. Once optimal readings are obtained, lock
the vertical movement on both heads (TX and RX).
7.2.12 - Press button 17 and check thatled 18 goes off. Check that after a maximum recovery
time of two minutes, the value shown on the display (2) reaches 6 VDC, and that the
centre led in the array lights.
7.2.13 - Press button 10 until led 7 lights up; check that display shows voltage ofbetween 2.5
and 6.5 VDC. This RAG value is directly proportional to the distance between transmit-
ter and receiver heads. Press button 10 until leds (6) light.
7.2.14 - Adjust "SEN" trimmer on receiver head (fig. 29) until displayed value lies between 0
and 9 VDC. OV corresponds to maximum and 9V to minimum sensitivity.
7.2.15 - Adjust "INT“ trimmer, next to “SEN" trimmer (fig. 29), until the desired integration le-
vel is obtained. , ,
7.2.16 - Press button 15 until led 16 lights. This indicates that the buzzer is enabled (fig. 26).
Make sure that the buzzer remains silent during the absence of movement in the protected
field. Ifthe buzzer sounds, press button 14 until it is mute.
Ifthe buzzer is already mute when this function is switched on, press button 13 until the
buzzer sounds intermittently, then press button slightly until it is mute again.
7.2.17 - Run the barrier crossing tests, checking first the intermittent buzzer alarm and then the
continuous buuing indicating that the barrier has been crossed.
Check that the buzzer does not sound when there is no movement in the field. Lt" this
occurs, even intermittently, the field is disturbed.
Ifthe barrier is crossed by very large targets, the CHANNEL LED (fig. 29) may also go out.
This indicates that the RF signal has been interrupted,
Barrier set up must suit specific user requirements. However, it should be borne in mind that ex-
cessive sensitivity will tend to cause the alarm to go off under not strictly alarm condi-
tions. Each individual case will require a compromise in parameters. Furthermore, it
should be remembered that the sensor’s perception of barrier crossing speed is affected

by the integration adjustment, while the perception of the mass crossing the barrier is af-
fected by the sensitivity adjustment.

7.2.18 - The STC 95 features an RCA socket (23) (fig. 26). This can be connected via a suitable LA
cable to an oscilloscope (any type currently on the market), for analysis of the received
signal wave-fem, The wave-form should be of the type shown in figure 30 if the tran— E
smitter and receiver heads are properly aligned.
T’oor alignment will lead to a received signal wave—fonn like that in figure 31, where noise can
be seen at the tips of the square wave. This means that the received signal is not of good
quality In this case, the alignment tuning operations should be repeated until the wave—
form is like that in figure 30.
All data on the measurements taken on the installation should be written in the test cards provi-
ded with each barrier. This will make any assistance operations much easier.
7.2.19 - Refit the radomes to the receiver and transmitter heads. Tighten down the mounting
screws to ensure water-tightness.
A bad connection produces a waveform like the one shown in fig. 31. Note the presence of noise
on the cusps of the square wave. This means that the signal received is not good. In this
case repeat the aiming operations until the waveform in figure 30 is achieved.
All data relating to measurements carried out on the system should be written on the test cards
which are supplied with every barrier. This will make assistance operations eittremely
easy.
Replace the radomes and fixthem evenly with the appropriate screws in order to achieve good
water-tightness.

8. MAINTENANCE
When breakdowns occur at abarrier, it is necessary to proceed as follows:
8.1 - Go to the receiver and, afier removing the radome, plug in the connector of instrument STC
95 as described in points 7.2,1/7.2.2.
8.2 - Check that the "CAN" and "ALL" leds (frg. 29) are lit; obviously this check must be carried
out with no moving obstacles in the protection field.
8.3 — Press key Flo on the STC 95 in order to light led 4 (fig. 26).
Check that the 13.8 DC voltage is within ilO%.
Ifthe voltage is lower, it means the power supply unit is not operating correctly, or the AC
power supply is missing; the latter possibility is also shown by the "GRID" led going
out (fig, 29). In this case, check that there is a voltage across the primary winding of the
transformer (220 V) and its efl'rciency.
In connection with this, it should be remembered that if the transformer is not closed inside a sea-
led case, water may corrode the connections, and these may consequently disconnect
and possibly cause irreversible damage to the transformer.
In this case, replace the transformer and make sure its container is hermetically sealed.If, on the
other hand, the readings are higher, it means that the power supply unit is faulty, or that
the installer has adjusted the voltage regulation trimmer.
Check the voltage calibration by proceeding as follows:
Disconnect the battery fastons and connect them to the prods of a precision electronic voltmeter
set to the 20 V DC scale. Ifthe reading is not 13.8 V DC adjust the RT trimmer until the
.. reading reaches 13.8 V DC.
Ifit is not possible to set the voltage to that value, it means the regulator is unrepairable.
In this case, it is necessary to replace the printed circuit. Ifthe problem can be solved by ad-
justment, remember to block the trimmer in position with a drop of fast-drying paint.
8.4 — ‘Press key 10 on the STC 95 until led 5 comes on (fig, 26).
Check that the voltage read in the "FIELD" RX function is 6 V DC 11 0%.
When there are no moving objects in the protection field, this reading is very stable.
*' Any oscillations greater than $500 mA show system instability which may either mean interfe-
rence due to moving objects in the protection field or barrier malfunction.
Occasional large oscillations (> lV) may mean transmitter malfunction; in this case, the transmit-
ter kit should be replaced.
Small oscillations are almost certainly due to interference in the protection field (tree foliage,
grass waving in the wind, etc.); in this case the cause of the disturbance should be remo-
ved.
CIAS Elettroni ca Version 1.01
______________————-——————
Ifthe reading in "HELD" is different from the one shown (> t IV), it means the receiver has
broken down and therefore the RX kit should be replaced.
8.5 - Press key 10 until led 7 comes on, and check that the voltage reading on the display is be-
tween 2.5 and 6.5 V DC. This RAG value is directly proportional to the distance be-
tween the transmitter and receiver heads.
Check that the RAG has a value ofbetween 2.5 and 6.5 V DC. Ifthe reading on the display (2)
reaches values of greater than 6,5 V DC, it means that the signal arriving at the receiver
is very low, and therefore the connection is highly precarious.
This fact may be the result of two classes of problems, the first regards receiver breakdown, and
the second regards transmitter breakdown. In order to find out which event has occur-
red, it is necessary to carry out measurements on the nansmitter as shown in the next
chapter (points 7.1.3/7.1.4/7.1.5).
If, afier carrying out measurements on the transmitter, it has been shown to be operating correc-
tly, the receiver kit should be replaced as shown in the "USE OF ASSISTANCE KITS
AND THEIR FUNCTIO " chapter.
It is important to notice that the RAG measurement taken during assistance is not only useful for
revealing the breakdown but also shows any change in the environmental conditions of
the protection field.
In fact, if the installer has calibrated the system correctly, filled in the test cards which accompa-
ny each barrier, and written the RAG reading after the electronic aiming among the data
on the card, comparison between the value shown on the test card and the one read du-
ring assistance gives an immediate indication of the barrier operating state.
More precisely, if the reading during assistance is only slightly different from the one shown on
the card (i300 mV DC), the radio-frequency signal which arrives at the receiver is good
and ensures correct barrier operation.
In order to understand the meaning of the RAG measurement better, it is important to remember
that it is strictly connected with the quantity of the radio-frequency signal which arrives
at the receiver.
It can therefore easily be understood that a drop in this signal (which is equivalent to an increase
in the RAG value) compromises microwave barrier operation.
The signal received can be most efficiently checked by observing the waveform at the receiving
head as described in point 7.2.15.

Check that the 13.8 V DC, 9 V DC and 4.5 V DC voltages at the transmitting head are correct
within 11 V DC. If one of the two or both are higher or lower, it means that the transmit-
ting head has broken down. Replace with the TX assistance kit.
9. 1 USE OF THE ASSISTANCE KITS AND THEIR FUNCTION
The assistance kits consist of the processing circuit part and the microwave part; more precisely,
the transmitter kit (TX KIT) consists of a printed circuit and the microwave detector ea-
vity.
One important fact to bear in mind is that the assistance kit is always calibrated for maximum
performance, i.e. 200 metre range.
This is in order to make the task of the person called upon to provide the assistance easier
since it avoids having to have four different kits according to the ranges. In this way, the
installer no longer has the expense of buying complete barriers for the assistance, and the
operation is also made simpler and quicker,
Replacing the circuit and cavity parts both on the transmitter and receiver does not alter
the orientation of the barrier and therefore it is not necessary to carry out aiming operations
again.
