7.2 Multibeam
The Multibeam is an interface between a MCB and a 16 Microcell-type beam.
This simplifies the wiring of the beams and reduces the number of connections to the controller by
using RS-485 communication.
The product is composed of two modules, one controlling the emitters, the other controlling the
receivers and the communication. The connection between the Multibeam and the MCB consists of
a 4-wire cable, two for the power supply and two for the RS-485 communication.
A 5-wire cable makes the connection between the transmitter module (MBT) and the receiver module
(MBR). If this link between the two modules is not correct, the green light on the transmitting module
will remain off and the Multibeam will not work properly.
Anti-masking detection.
When one of the sensors is triggered (covered) for more than 10 seconds, this is considered to be
masking. This alarm will also be activated when a person stays to long in the detection sensors.
When one of the sensors notices masking, the acoustic alarm will be activated after ten seconds.
The alarm continues for three seconds. The alarm repeats after ten seconds.
7.2.1 Transmitter
The transmitter is located in the Slave unit.
With a multi-lane installation it can happen that the emitters of one Speedlane 900 have influence on
the receivers of the adjacent Speedlane 900.
This can be adjusted with the potentiometer on the emitter. With the potentiometer on the Multibeam
emitter, you can reduce/increase the power to the Multibeam emitters.
