MICROWAVE BEAM
Models BM60M, BM120M, BM200M and BM60M WS are microwave intrusion detection systems,
whose principle of working is the “field-interruption”.Thanks to the microprocessor managing the
signals, they are the ideal instruments for protecting big surfaces, both indoor and outdoor, thus
granting a high security standard.
Chapter 1: General Description
The system is made by a Transmitter and a Receiver which must be installed as a couple,
choosing the same working frequency among the 5 available, in both units (tx and rx) ,
through SW1 (4 dip-switch module) on board.
Compatibility with existing models
In case of replacement, choose the same frequency on the beam to be replaced (F1 by F1, F3 by
F3 etc.). In order to identify the corresponding frequency, use the chart “BEAMS CHANNELS”
Filter of selection and compensation
Any receiver is equipped with a selection filter choosing only the frequency of its channel and
rejecting the others, thus not making possible the elusion of the beam in case of use of a false
transmitter. Special self-adjusting and signal-elaboration circuits have been used in the receiver
for automatic compensation of temperature variations.
Detection Area
The shape of the irradiation area is very well defined and this allows a higher possibility of
detection and a reduction of false alarms risk.
These beams are manufactured exclusively with solid-state components and are tropicalyzed in
order to obtain a very good seal against weather conditions.
Chapter 2: Transmitter
The transmitter is made of a planar microwave emitting a narrow and directional higly-stable low
power beam.
A 4-dip-switch for setting working frequency is on board.
Check that the transmitter working frequency set is
the same as in the receiver coupled

Chapter 3: receiver of hard-wired systems BM60M, BM120M, BM200M
The receiver is made of a high-sensitivity electronic circuit coupled to the antenna; it detects the
signal transmitted in its channel and measures its intensity. Special techniques of signal-elaboration
allow to compensate the variations in the sorroundings and to minimize the effect of possible
perturbations due to small animals or birds.
A 4 dip-switch is on board for setting working frequency
Check that the working frequency of the receiver is
the same as set in the transmitter coupled.

Chapter 4: Receiver of the wireless system BM60M WS
The receiver has the same characteristics as the hard-wired models, with a few differences:
• the 4-ways dip-switch on board
adjusts both working frequency
and the zone address set. If, e.g.,
the beam is addressed on
frequency F2 (dip 1,3,4 in OFF and
dip 2 in ON), it is automatically
acquired as detector 2. It is not
possible to select the working
frequency and the zone address
in the control panel, in a separate way.
•the terminals on board are the supplying
(+ and -) an the signal reading (TP)
•the alarm transmission occurs for both
movement detection inside a pattern and
protracted absence of the signal
received (disqualification): the restore
transmission occurs a few seconds after
the signal is restored in the limits preset.
Check that the working frequency of
the receiver is the same as the
frequency set on the transmitter
coupled.

Overpassing this area might cause the

cause false alarms.

Chapter 5: Description of working
The two units (transmitter: TX and receiver: RX) must be positioned facing each other at the two
ends of the distance to protect. Be aware that the nature of the ground underneath, or special
weather conditions might affect the real range.
Working
The transmitter emits a modulated microwave signal (10,525 GHz), which is received by the
receiver and whose amplitude is compared with the programmed alarm threshold.
When an intruder crosses the microwave area, it causes a signal-intensity decrease under a
minimum level fixed; the receiver shows the alarm condition, lighting up a red Led indicator and
opening the contat of the alarm relay.
If the signal of the transmitter is not received for over 30 seconds, the alarm relay could go back
to quiet condition and the negative to terminal D (disqualification) fails until signal restoring.
For this reason, in the hard-wired system, it is
suggested to make the connection
described in the chapter
concerning disqualification.
The drawings identify the
natural shadow areas
in the immediate
sorroundings of the
two units, which extend
for about 3 meters, in a
typical installation at 1 - 1,2 m
height.
Note: the diagrams of the patterns shown in the drawings are an indication and a guide
during installation. They do not represent the real radiation diagram of the antennas as
they may be subject to variations due to environmental context.

Chapter 6 : Positioning of the beams
For a correct installation of the system, choose carefully the positioning of the two units, according
to following advice:
Drawings identify the correct positioning of transmitters and receivers, in order to eliminate any
possible shadow area.
The drawings here below show how one or more couples of beams have to be positioned for
reaching the distance required.
BE CAREFUL: only elements with different frequencies (F1, F2, F3, F4, F5) and of the
same type (TX/TX or RX/RX) can be installed in proximity one to the other; in order to
avoid interferences between transmitters and receivers belonging to different couples.
The typical installation of
BM M system consists in
sorrounding the area to be
protected by use of more
beams couples in order to
obtain a proper perimetric
fence

If, in a perimetric installation, the
beams cross the patterns, they
must always be installed in
pair (2, 4, 6 etc.)

necessary to
avoid installing a
