BM 120 M

Microwave Barrier 120 meter Range

BM is composed of 2 units – 1 transmitter (TX) and 1 receiver (RX) – installed at a maximum distance of 60, 120 or 200 meters. The transmitter emits continuously the microwave in direction of the receiver. The intruder who passes through the 2 units reduces consecutively the received signal, up to reach the alarm level and generate the alarm. The perimeter protection is achieved by installing multiple barriers in a single thread.

Product Features

HIGHER SECURITY
The security area is genuinely so wide as high (up
to 4 x 3 meters) that it is impossible to cross without generating an alarm and provides higher security compared to other technologies.

LOWER FALSE ALARM RATE
Setting a pet immunity is easy: the alarm level is programmed to ignore small animals and generate fewer unwanted alarms.

INTEGRATION CIRCUIT
The security may be increased automatically thanks to its build-in integration circuit which amplifies the possible conditions for an alarm and triggers more easily.

DISQUALIFICATION
BM distinguish a real alarm from a disqualification
situation (like a van parked between the barriers).

COMMON INTERFACE AND INSTALLATION
With the poles, BM is only 120 cm high: it is easy and quick to install them, so the cost of installation is lower compared to other technologies. It is also simple to set perfectly thanks to a few trimmers and dip-switches. Finally, thanks to its regular NC outputs, BM works with all alarm and CCTV systems.

MICROWAVE PLANAR ANTENNA
Since 2003, BMs integrate planar antennas which reduce of 20% the sensibility area compared to former parabolic antennas. Longer distances BM can be installed for the same perimeters and costs are saved. In addition, to be protected from rain, the parabolic antennas use big expansive difficult-to-handle waterproof housings when the BM’s planar antennas are highly protected by tropicalization and installed in a highly resistant protective cover that avoids condensation and its consecutive rust development.

CLIMATIC ENVIRONMENT
BM operate in all weather conditions (snow, rain, fog) without distances reduction, unlike the active infrared barriers. If the temperature reaches less than -5°C, it is possible to place a TERM1 heating kit. BM temperature range is -20/+55°C.

POWER FEED
BM M and BM HP are 13,8 Vdc powered. VAC series is directly fed by the main (220 Vac) and include an optional backup battery to compensate for an electricity absence. Main power feeding simplifies the wirings and decreases the installation cost.

MARKETS
BM are perfect for all the perimeters: gardens, houses, borders, warehouses, airports, commercial resorts, car and trucks parks, civilian, industrial, military, nuclear and electrical plants.

Digital BM HP Advantages

AUTOMATIC GAIN CONTROL (AGC)
The environmental variations may improve or deteriorate the microwaves level reception over time. An Automatic Gain Control circuit automatically optimizes the level to maintain it flat: the settings are easier, the security is higher.

REDUCTION OF THE SENSIBILITY AREA
BM HP may reduce digitally by up to 30% the area of sensibility and then ignore the movements in the peripheral objects (i.e. from fences or trees) which are the origin of unwanted alarms.

FALSE ALARM FILTER
BM HP barriers record automatically up to 3600 events it is possible to classify between good and false alarms. BM HP verifies then the new events according to this database and stops the unwanted alarms.

DIGITAL INTERFACE
Additionally to the NC outputs and other regular settings, BM HP present a USB and an RS485 port to be coupled to an RS485 hub or an AVS ELECTRONICS’ control panel.

SOFTWARE
Thanks to the local USB port or remotely by PSTN, GSM or IP, HPWIN software shows all the parameters, an oscilloscope, the 3600 last alarm events (with date and time) and proposes all the tools to set the barriers.
