1.4.3 3 Principle of operation
1.4.3.1 Access cycle:
1.
In the initial state the turnstile glass blades are located perpendicular to the body block
access.
2. The turnstile is opened for access in the direction "А" or "В" after the appropriate
command from ACS or control panel is issued.
3. Green arrow is lit on LED display and glass blades go fully to slots, i.e. they open. A
pedestrian is able to access through the turnstile freely.
4.After pedestrian exit from control area, the "closed" mode is set until next access. Blue LED
is lit. Blades are reliably closed preventing attempts of unauthorized access.
More detailed description of the turnstile operation modes is given in section 1.6 "Description
and operation of controller as an integral component of the turnstile".
1.4.3.2
12V DC power voltage is provided by power supply unit.
1.4.3.3
In case of mains power supply failure, the turnstile is automatically switched to power
supply from 12V, 7A•h battery (optional), which ensures the turnstile's operation within 2 hours.
1.4.3.4
The turnstile wiring and connection diagrams are shown in Annex C.
1.5 Instrumentation, tools and accessories
Dedicated tools are not required for the turnstile installation (multi
-
purpose measurement
instrumentation and installation tools are sufficient).
1.6 Description and operation of controllers as integral component of the turnstile
1.6.1
Controller AUIA.206.21.20.00
1.6.1.1 Appearance of controller AUIA.206.21.20.00 is shown in
Figure 8.
1.6.1.2 Description of operation
The controller provides algorithm of operation of the whole turnstile. It is assembled on the
120 х 80 mm size card from foil
-
clad textile laminate, on which electronic components and
terminals for connection to other turnstile units as well as for connection to control peripherals
(ACS, control panel etc.) are located.
The controller generates signal for 7 infrared transmitters and picks up signal from 7 infrared
receivers that enables to detect human (or object) presence in the turnstile access area with high
probability. Furthermore, the controller AUIA.206.21.20.00 controls light and sound indication,
receives commands from control panel using interface RS
-
485, picks up commands and generates
report signals for ACS via signal inputs and outputs as well as controls operation of motor
controllers (РВС.201.01.00.00).
The controller and therefore the turnstile can be in the following modes:
•
"INITIAL STATE".
•
"SINGLE ACCESS IN THE DIRECTION А".
•
"SINGLE ACCESS IN THE DIRECTION B".
•
"SINGLE ACCESS IN BOTH DIRECTIONS".
•
"FREE ACCESS IN THE DIRECTION А".
