DESCRIPTION OF THE PRODUCT

2
AND DESTINATION OF USE
The MOTB digital selector is a device that permits to check and allow access to
places or services, exclusively to authorised staff.
AT TENTION! – Any use different to that described and in environmental
conditions different to those stated in this manual must be considered
improper and prohibited!
With MOTB it is possible to command an automation by entering one of the
previously-memorised numerical combinations from the keyboard.
It has a removable memory; this can be programmed (see chapter 4) also with
the aid of the Nice O-Box and MOU programming units.The MOTB communi-
cates with the devices present in the automation by means of the "Bluebus"
system. This allows to make the electric connections with the aid of only 2
wires, on which both the electrical input and the communication signals transit.
The electric connection is the parallel type and polarities do not have to be
respected. Every device connected to the control unit is recognised individually
during the learning phase thanks to the addressing of the electric jumper pres-
ent in the keyboard. Moreover, during the learning phase the command devices
are associated to the control unit by an unmistakable code, which guarantees
maximum safety in order to prevent fraudulent attempts to replace the device.
