2.2 Splitter
Description
The splitter serves for connection of central unit with announcers of given lift. Six wires
are connected to the central unit (power, audio, data). Announcers (audio units) are
connected to the splitter using a two-wire bus. The splitter also contains a make/break
contact for the function of blocking the lift. There can be a maximum of 8 splitters
(according to the number of lift shafts). Each splitter must be configured for a different
address (number of lift shaft) for the system to work. The address is configured as 2-8
(lift 2-8). Lift 1 is the central unit.
The splitters are connected in series, i.e.., one after the other. It is not possible to
connect them in parallel. The system Lift8 would be unstable. On the last splitter
(furthest from the central unit) the termination resistance (jumper) is connected.
It is possible to power a splitter from the local power.
Electrical Installation
Connection to main bus
Pull the push-in terminal from the connector of the main bus and connect six wires
