6.5 Connecting devices to the communication bus
The bus wires must be run in one cable.
The total length of the expander bus may not exceed 600 m.
The device can be powered directly from the control panel, if the distance to the
control panel does not exceed 300 m. Where the distance is greater, another power
source must be provided for the device (power supply or expander with power supply).
The Table 1 shows the number of wires required for correct connection of the device to the
expander bus if conductors with 0.5 mm diameter are used.

For most devices to be connected to the communication bus, setting of a suitable address is
required. Two devices must not share the same address (otherwise their identification will be
impossible). For information on the requirements related to address setting, please refer to
the sections describing how specific devices are to connected.
6.5.1 Connecting keypads
The control panel supports up to 4 keypads. These can be either wired or wireless keypads
(the wireless ones can only be installed after starting the control panel). Addresses of the
keypads must be set within the range from 0 to 3. For how to program addresses of the
keypads, please refer to p. 17.
