WIRING THE S2000-2 FOR TWO ENTRANCE DOORS MODE
Figure 4 shows the wiring diagram for a S2000-2 controller operating in the Two Entrance Doors
mode. In this operating mode alarm loops are not involved in access strategy and are not shown in
the connection diagram. However they can be used as intruder alarm loops in the Orion system in
which the S2000-2 controller operates on-line (see Alarm Loops Section of this Manual).
The first door equipment (the reader, the lock, the EXIT button, the door sensor) are connected to the
controller terminals marked with digit 1 at the end. The second door equipment is to be connected,
accordingly, to the terminals marked with digit 2 at the end.
Electromagnetic locks (strikes) can be powered by the same power supply as the controller, or by the
separate one. If its are powered by the same power supply, power circuits of the controller and the
lock must be wired separately and be connected only at the power supply terminals.
Please note that Free Pass Access mode can not be implemented for an access point if the electric
strike is used as a locking unit.
If the readers are suitable for input current consumption more than 100 mA or they are located far
from the controller (100m and above), to power them the separate pair of wires must be used which
leads directly to the power supply (against the case shown on the scheme when the readers are pow-
ered via the controller terminals).
If a reader is powered by a separate supply, the GND circuits of the controller and the reader must be
coupled, i.e. the terminal +12V1 of the XT2 terminal block (terminal +12V2 of the XT3 terminal block)
is not to be connected to the reader, while terminal GND1 (GND2) is always connected to it.
When passing through the doors in backward direction the lock is opened by EXIT button pressing.
