WIRING THE S2000-2 FOR SWING-BEAM BARRIER MODE
Figure 8 shows the wiring diagram for a S2000-2 operating in the Swing-beam Barrier mode.
In this mode the first relay is used to lift the swing-beam, while the second relay is used to lower it
down. ENTRY and EXIT buttons are used to grant access remotely, e.g. from a guard post.
It is implied in this diagram that lifting the swing-beam is implemented by closing swing-beam barrier
control unit contacts denotes as ‘Lift’, while lowering the swing-beam down is implemented by closing
swing-beam barrier control unit contacts denotes as ‘Lower’. If swing-beam barrier control requires
switching of voltage more than 30V, or electric current more than 7A, or power more than 100W, po-
wer relays has to be connected to the controller relay outputs. In such a case the controller relay will
switch the contacts of the power relay, while the power relay contacts will in turns switch the contacts
of the swing-beam barrier electric drive.
If only the opening relay is required to control the swing-beam barrier (with lowering being imple-
mented automatically after cancellation of the open command) then the first S2000-2 relay is to be
used. The Relay Activation Time in such a case is set to value no less than standard passage time
(30s), preventing a car from swing-beam being lowered down on it (the relay 1 will be activated until
the car has driven off the swing-beam barrier).
Car presence detectors causing the controller to make access decisions only if there is a car near the
reader when a key is presented to it are to be connected to the alarm loop contacts of the controller.
Passage sensors are used for such an operation mode not only to detect a passage but to prevent
the swing-beam from lowering down on a car. If at least one of the sensors is activated, the swing-
beam will not be lowered. For this reason the sensors (generally, optical beam sensors) are located
from both sides of the swing-beam barrier, so that any car located under the swing beam causes at
least one car presence detector to actuate.
The diagram shows how to wire NC output dry contact passage sensors that are opened when the
access is being granted. Wiring passage sensors of another output type is considered in Connecting
Door or Passage Sensors Section of this Manual.
Instead of two passage sensors located at the both sides of the swing-beam barrier it can be possible
to use a single sensor located strictly under the swing-beam (near the swing-beam). In such a case it
is wired in parallel across the relevant inputs of both control channel of S2000-2 as shown in Figure 7.
Along with the LEDs of the readers (or instead of them) two traffic lights operated by +5 V CMOS
logic signals can be connected to the LEDG1, LEDR1 and LEDG2, LEDR2 terminals of the controller.
In order to control the swing-beam barrier manually from a guard post, the buttons connected to the
EXIT1 and EXIT2 terminals of the controller are used. If the swing-beam barrier is lowered down,
pressing any of the buttons will lift the swing-beam, and if it is lifted up, pressing any button lowers it
down, even if the current procedure has not been competed.
