CONNECTING DOOR OR PASSAGE SENSORS
DOOR1 and DOOR2 terminals of the С 2000-2 controller (see Figure 3) are intended to connect door
sensors (or door open detectors, or door contacts) as well as various passage sensors or turnstile
rotation detectors. These sensors are used for implementing extended S2000-2 functions, such as
PASSAGE messages generating and transmitting them to a network controller, monitoring doors for
being forced or held open, anti-passback rules checking, time&attendance monitoring, relay activation
while door being open/closed and so on.
If none of these functions is required these circuits can be out of use and the relevant terminals are to
be left disconnected only if the S2000-2 controller operates in the Two Entrance Doors, One En-
trance/Exit Door and Turnstile modes. In the Swing-beam Barrier and Two Sluice Doors modes using
DOOR1 and DOOR2 circuits and connecting passage sensors are obligatory.
The following detection devices can be brought into the DOOR circuits:
−
Magnetic contacts
−
Optical passage sensors
−
Turnstile rotation sensors
−
Optical car passage sensors
These detectors can be equipped with both NC and NO outputs, open collector outputs, as well as
digital outputs (active 0 or active 1 with +5V CMOS levels).
Figure 16 shows wiring diagrams for connecting passage sensors (door sensors) to the S2000-2 con-
troller. For all the diagrams it is supposed that in normal conditions (the door is closed, the turnstile is
in home position, no car is located near the swing-beam barrier) a 8.2 kOhm terminating resistor is
included between the DOOR…and the GND circuits (the voltage on a DOOR… terminal relative to
GND is about 2.9V). When a passage sensor has been activated, the terminating resistor circuit is
either open (voltage at a DOOR… terminal is about 5.0V) or short circuited (voltage at a DOOR…
terminal is about 0V).
A
passage sensor must generate a signal of at least 50 ms length, it is necessary for the controller to
detect a passing event.
