1.4.2.2 The turnstile’s status (
Fig
. 5
) is displayed by the LEDs
1,2,
installed on the pedestal
frame elements. Constantly lit blue LED means the turnstile initial state. In case of attempt of
unauthorized access red LED starts blinking and sound signal is generated. When opening
command is received, signal is transformed to green arrow from the side of authorized access. If
unauthorized access is attempted when blades are open, the blades will close if there is no any
obstacle in the blade movement area
.
1.4.2.3
Seven infrared sensors
3
, located on the turnstile side panels from access side, are
designed for detection of the turnstile access, preventing closing of blades during pedestrian
access in immediate proximity to them and minimizing potential for injury during the turnstile
access.
1.4.2.4 Blade
4
is made from 10 mm thick tempered glass and is located in the middle of the
pedestal body, pivotally connected with actuator. Each blade is actuated by separate servomotor.
Additional pedestal is equipped with two servomotors (one per each access way), while margin
pedestals (left-hand and right-hand) are equipped with one servomotor.
1.4.2.5 In case of 230V main power failure the turnstile blades will remain in the position in
which they were, and the turnstile operation will be maintained from battery (if available).
1.4.2.6 The pedestal crank-and-rocker mechanism, shown in Figure 5, provides reciprocal
movement of the pedestal telescopic glass blade.
1.4.2.7 Inside the turnstile body the panels are fixed on which controllers, power supply
unit, battery and terminal blocks to be connected to 230V mains and control devices are located.
Controllers РСВ.201.01.00.00 control the turnstile motors analyzing signals from magnetic
sensor, and provide motor overload protection. Controllers analyze infrared sensors, receive
control commands from peripherals (control panel, ACS etc.), control LED displays and generate
feedback signals for ACS.
1.4.2.8 External control panel has the following functions: single entry and single exit, entry
and exit LOCK, free entry and exit
1.4.3 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.
