Page 3: Chapter 1: General Description
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. -
Page 4: Chapter 3: Receiver Of Hard-Wired Systems Bm60M, Bm120M, Bm200M
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. -
Page 5: Chapter 4: Receiver Of The Wireless System Bm60M Ws
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... -
Page 6: Chapter 5: Description Of Working
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. -

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: 3 mt 3 mt 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... - Page 8 It is absolutely necessary avoid installing a transmitter near a receiver belonging to another couple If, in a perimetric installation, the beams cross the patterns, they must always be installed in pair (2, 4, 6 etc.) - 8 -...
- Page 9 In order to extend the height of the protection, two couples of beams can be installed as shown in the picture. In this case, it is suggested to use couples of beams having close working frequency (two couples with frequency F1 and F2 or F3 and If the fence is made of bushes or metal fences subject to possible movement, the minimum distance must be 1 meter for BM60M...
- Page 10 A corridor large not less than 0,6 meters for BM60M and BM60M WS and not less than 2 meters for BM120M and BM200M, must be left free from obstacles between transmitter and receiver; a clear visual must always be granted in this area The suggested height for the installation is between 1 and 1,2 meters.
- Page 11 It is possible to install the system BM60M and BM60M WS also to protect walls. In this case, the system of installation shown in the drawing can be used, in order to avoid false alarms caused by cats or birds. In this case also, the height from ground must be between 1 and 1,2 meters.
- Page 12 • Should any pet be present and free in the installation area, it is suggested to carefully adjust sensitivity, in order to avoid the risk of false alarms due to the passage of these small targets in the areas which are very sensitive at the ground. To further decrease this risk, the height of installation of the couple can be increased a little bit.

Chapter 14: Sensitivity Adjustment Turn trimmer SENS clockwise in the position of minimum sensitivity and make a trial walking in the central point of the distance covered (point of minimum sensitivity of the system) and check the behaviour of the green led. If necessary, increase the sensitivity progressively until obtining the answer desired After any sensitivity and orientation adjustment, it is necessary to wait about 20 seconds in order to have all signals set and make a new trial... -

Chapter 15: Kit TERM (optional) Resistence fo inside heating • For installation in an indoor or outdoor place where temperature can go lower than 0 C, it is necessary to use the heating kit Term 1 in both Receiver ad Transmitter. This has to be done in order to avoid formation of condensation which might affect the good working of the electronic circuit. -
