10 ACCO-NT
SATEL
Fig. 2. Diagram showing how the access control modules are connected to the ACCO-NT
control panel. The control panel can be connected to the bus at any point. Place 100
Ω
(±
10%) resistors at the beginning and at the end of the bus. Connect the COM terminals of all
modules and control panel with an additional cable. The modules in the drawing are
designated by ordinal numbers, not addresses.
6.6 Connecting the devices to expander bus
The bus wires must be run in one cable.
The total length of expander bus must not exceed 1000 m.
The expanders should be power supplied in accordance with description contained in
the manuals delivered with respective devices.
Table 2 shows the number of conductors required for correct connection of the device to the
expander bus if 0.5 mm diameter conductors are used.
