- balcom Duo-PLUS is a 2 wire BUS-system which allows the bi-direktional
speech of one or more BUS - Telephones between the flat and the
door-station
- Simple one-man programming
- The programming will not be lost due to Power-failure or through the
changing of some components
- The programming can be simply changed if necessary
- The use of standard existing Bell-buttons is possible
- The BUS-Telephone BHT 9800 for the flat has a non-polarity connection
and must not be opened, neither for the installation or programming
- The electrical connection of the 2-wire BUS is made via terminal-block
on the wall-mounting-plate
- Each flat has a choice of 4-melodies for the main door
call, and a further
2-melodies for the flat-door call
- Up to maximum 255 BUS-Telephones can be connected to the 2 wire
BUS - Line
- The maximum BUS-Line impedance is 600 Ohm, therefore the cable length
can be naerly neglected
- An extension of ut to 10 door-stations* (1 Master and 9
Slaves) can
be connected to the BUS-system (*in preparation)
