5 PRODUCT DESCRIPTION
5.1 Main features
•The turnstile is designed either for indoor application or outdoor (see Clause 2).
Turnstile housing is produced from high quality stainless steel with ABS plastic
covers.
•The turnstile plastic side covers are radio transparent that allows concealed
mounting of the ACS readers inside the turnstile housing.
•The turnstile can be operated from the RC panel or WRC as well as from an ACS.
•The turnstile is equipped with automatic anti-panic folding arms. Automatically free
of passageway is performed by bringing the barrier arm into vertical position at a
power loss or by alarm signal. A purpose-designed «Fire alarm» control input is
intended for opening the turnstile at the fire alarm command or from emergency
opening button.
•The turnstile houses 2 LED indication displays intended for status and passage
direction indication. Besides, the turnstile has an extra indication of passage
direction on its side posts.
•The turnstile has outputs for connection of remote indicators.
•The turnstile has relay outputs for connection of an intrusion detector and a siren.
•There are two modes for the turnstile control — a pulse control mode and a
potential control mode.
•After each passage the turnstile provides automatic complete rotation of the barrier
arm to home position, i.e. automatic reset.
•After the turn of barrier arm for more than 60º angle its reverse rotation is blocked.
•Smoothness of reset and quiet operation are ensured by a damper.
•The optical arm rotation sensors are built into the turnstile housing to ensure
accurate count of inputs to an ACS.
•The turnstile is supplied with safe voltage — maximum 14V.
•Galvanic decoupling of the outputs ensures noise-immunity of the turnstile
electronics.
•Installed in a line several turnstile housings form a secured passage without
installation of extra guide barriers.

On control board there is a microcontroller, which processes incoming control commands
(inputs Unlock A, Stop, Unlock B and Fire Alarm), traces the condition of barrier arms
optical sensors and basing on received data generates commands on control unit of the
turnstile. Besides, microcontroller generates signals on outputs: for indication on RC panel
(outputs Led A, Led Stop and Led B), for outer indication (outputs Light A, Light B), for
passing in a corresponding direction (PASS A and PASS B), for turnstile readiness to run
the command (Ready), for alarm (Alarm), to retransmit the signal of intrusion detector
condition (Det Out).
The CLB (Fig. 5) includes:
•X1 (LED), X2 (SENS), X3 (MOTOR) connectors to connect the indication module,
optical arm rotation sensors and control mechanism with a locking device (from the
X1, X2, X3 connectors with the turnstile cable).
•XT1.L (In) – connector block to connect the RC panel / WRC / ACS controller inputs
as well as an emergency opening device (Fire Alarm) and intrusion detector
(see Clauses 5.3.1, 5.3.2, 5.4.1).
•XT1.H (Out) – connector block to connect a siren and ACS outputs, providing the
turnstile status data to the ACS controller (see Clause 5.4.1).
•XT3 (+12VDC) – connector block to connect the turnstile power supply.
•XT4 (Light A) and XT5 (Light B) – connector blocks to connect “open/closed”
remote indicators, one indicator per each direction (see Clause 5.4.3).
•XT6 (AntiPanic) – connector block to connect the electromagnet of automatic
anti-panic opening device.
•J1 – connector to select the turnstile control mode, the jumper is fixed — the pulse
control mode, the jumper is not fixed — the potential control mode. The jumper is
fixed at the factory before the delivery (see Clause 5.2.6).
•J2 – connector for programming.
•Power – power LED indicator on the control board.
For convenience, connection contacts of turnstile power supply and turnstile control units
are set on the bracket on connector block XS1. Connection is conducted out in
accordance to the connection diagram of the turnstile and optional equipment (see
Fig. 13). Electric power supply is carried out through the power cable (13).
5.2.5 Parameters of control signals
The turnstile is operated by input of a low-level signal to the XS1 connector block contacts
“Unlock A”, “Unlock B” and “Stop” relatively to the “GND” contact. As the control element
there can be used a normally open relay contact or a circuit with open collector output at
that. At the emergency the turnstile control is carried out by removing of a low-level signal
from the “Fire Alarm” contact relatively to the “GND” contact. As the control element there
can be used a normally closed relay contact or a circuit with open collector output at that
(Fig. 6 and 7).
Emergency unblocking of the turnstile is carried out by removing of a low-level relatively to
the “GND” contact signal from the “Fire Alarm” contact. As a control element there can be
used a normally closed relay contact or a circuit with open collector output at that. All
turnstile control commands coming to other outputs are ignored (see Clause 5.3.2).
During the low signal injection on Fire Alarm output directions switch to the mode
according to signal levels on inputs Unlock A, Unlock B and Stop.
Activation of intrusion detector is controlled by removing of a low-level relatively to the
“GND” contact signal from the “Fire Alarm” contact. As a control element there can be
used a normally closed relay contact or a circuit with open collector output at that.

Assembly & Operation Manual
12
Note:
For generation of high-
level signal at all input contacts (“Unlock A”, “Stop”, Unlock
B”, “Fire Alarm” and “Detector”) 2kOhm resistors connected to the power supply bus
“+ 5 V” are used
Figure 6 – ACS control element - normally open relay contact
Figure 7 – ACS control element - circuit with open-collector output
The control element must provide the following signal characteristics:
the relay contact as the control element:
minimum switched current .......................................................... no more than 2 mA
closed contact resistance
(with the resistance of the connected cable) ........................ no more than 300 Ohm
the circuit with open-collector output as the control element:
voltage at the closed contact
(low - level signal at the CLB input) ............................................ no more than 0.8 V
5.2.6 Control modes of the turnstile
There can be two control modes of the turnstile: pulse and potential. In both modes
turnstile control is conducted by command issuing (namely by combination of control
signals) on operational control inputs: Unlock A, Stop and Unlock B and special control
input Fire Alarm. Depending on a chosen mode the procedure of command issuing
changes (see table 5 and 6).
Warning!
Installation and removal of the jumper is to be done only when the turnstile is
switched off.

TTD-08A Electromechanical Box Tripod Turnstile
13
The control mode is set by removal / installation of the jumper on a J1 connector on control
board. The J1 connector location is shown in Fig. 5. An installed jumper corresponds to
the pulse control mode. In order to switch to potential mode, uninstall the jumper. The
change of control mode will take place after switching on the turnstile.
Pulse control mode
The mode is used to control the turnstile with RC panel, WRC and CLB, outputs of which
support pulse control mode.
Duration of control signal during command issuing on operational control inputs should be
not less than 100mc. The passage waiting time is 5 seconds and it doesn’t depend on
duration of control signal (impulse).
Description of turnstile work in pulse control mode is described in Table 5 Procedure of
command issuing is described in Appendix 1.
By removal of low-level signal from special control input Fire Alarm, turnstile switches to
Fire Alarm, mode and therewith all incoming commands of turnstile control are ignored
(see Clause 5.3.2).
During low-level signal issuing at the input Fire Alarm command «Passage Denial» is sent
and turnstile rotary mechanism is blocked.
Potential control mode
The mode is used to control the turnstile with CLB, outputs of which support potential
control mode.
Duration of control signal during command issuing on operational control inputs should be
not less than 100mc.
The passage waiting time equals the duration of control signal: if by the moment of the
passage in authorized direction at the entrance of this direction there is a low-level signal,
then the turnstile will stay open in this direction.
At the low-level signal inputting to the “Stop” input, both directions will lock for the time of
the signal duration regardless of the signal strength at the inputs “Unlock A” and “Unlock
B”. By the removal of a low-level signal from the “Stop” input, the directions will set to the
modes according to the signal strength at the inputs “Unlock A” and “Unlock B”.
Description of turnstile work in potential control mode is described in Table 6. Procedure of
command issuing is described in Appendix 2.
Note:
To organize single passages in potential control mode it is advisable to remove low-
level control signal from control input Unlock A/ Unlock B
during activation of relay
output PASS A / PASS B of corresponding direction.
5.2.7 Algorithm of the control mechanism
Procedure of turnstile work in the pulse control mode in case of a single passage in one of
directions:
1. From control unit (RC panel, WRC, ACS) on control board inputs comes a
command (combination of control commands) for execution of a single passage in
one of directions.
2. Microcontroller, fixed on the control board, processes the received signal
combination and forms a command to the turnstile control unit to unblock the rotary
mechanism. Turnstiles hold time counting starts in the blocked mode.
3. Control mechanism unlocks the rotary mechanism for the rotation in a chosen
direction. Passage in this direction becomes possible.

Assembly & Operation Manual
14
4. After the passage is complete, barrier arms rotation angle is monitored by
microcontroller with optical sensors of control mechanism. With rotation angle of
more than 67° the act of passage is registered. One of relay outputs PASS A or
PASS B, according to the direction of the passage, becomes active. Microcontroller
forms the instruction to the control mechanism for blocking the turnstile rotation
mechanism.
5. After the passage is complete, i.e. when barrier arms are reset to the closed
position (120° rotation), turnstile rotation mechanism is blocked. Relay output
PASS A / PASS B becomes normal.
6. If barrier arms rotation hasn’t started, then the command for blocking rotation
mechanism is formed as hold time passes in unblocked mode (5 seconds from
receiving the instruction by default).
7. Turnstile is ready for next passage.
5.3 Control devices of the turnstile
The turnstile can be operated from the following control devices:
•the RC panel;
•the WRC;
•the ACS controller.
The above devices can be connected to the turnstile as follows:
•any device separately;
•in any combination with each other;
•all devices simultaneously (in parallel).
Note:
At the parallel connection of the above devices to the turnstile the superposition
of the control signals
from them may occur. In that case the turnstile response will
conform to response to the obtained combination of input signals. (App. 1 and 2).
5.3.1 Connection of the RC panel
The RC panel is connected to the contacts GND, Unlock A, Stop, Unlock B, Led A,
Led Stop and Led B of the XS1 connector block in accordance to the connection layout of
the turnstile (see Fig. 13).
Figure 8 – Standard RC-panel orientation regarding IP-Stile

Standard orientation of RC panel in regard to the housing is shown in Fig. 8. If working
space of the operator is located on the opposite side of the housing, then for convenience
of operation it is necessary to swap RC panel cables, connected to contacts Unlock A and
Unlock B, as well as Led A and Led B correspondingly (see Table 2).
Note:
The WRC is connected to the contacts GND, Unlock A, Stop and Unlock B
of the
XS1 connector block. Power supply of the WRC is connected to the contact +12V of
the XS1 connector block.

5.3.2 Emergency opening device Fire Alarm
The emergency opening device is connected to the contacts “Fire Alarm” and “GND” of the
XS1 connector block in accordance with the connection layout (see Fig. 13).
If the “Fire Alarm” input is not used, it is necessary to set a jumper between the contacts
“Fire Alarm” and “GND”. This jumper is preset at the factory.
During release of control signal on Fire Alarm input, turnstile switches to the emergency
Fire Alarm passageway opening. In this mode all incoming turnstile control signals are
disregarded. Turnstile rotation mechanism is blocked for rotation in both directions. Central
barrier arm falls down automatically by gravity and takes a vertical position which opens
the passageway. The following indication in both directions is displayed simultaneously on
indication modules: alternate switching on of green (for 1.25 sec) and red (for 0.25 sec)
turnstile indicators.
If signal Fire Alarm comes on the turnstile during the passage, then on indication blocks
appears an indication of Fire Alarm mode, but rotation mechanism blocking and passage
emergency opening will take place only after resetting of barrier arm to its home position.
After release of control signal Fire Alarm on indication modules appears red indicator of
passage denial and turnstile switches to the sleep mode with a dropped barrier. To
proceed with the work, a barrier arm has to be manually set in horizontal position, where it
fixes.
5.3.3 Control of the turnstile in ACS
Turnstile can be used as optional equipment while working as a part of ACS. Turnstile is
provided for installation of built-in access card readers under plastic side covers.
The ACS controller outputs are connected to the contacts GND, Unlock A, Stop and
Unlock B of the XS1 connector block.

Assembly & Operation Manual
16
The ACS controller inputs are connected to the contacts Common, PASS A, PASS B of
the XS1 connector block and to the contacts Ready and Det Out of the XT1.H connector
block.
Pin assignments of the connector blocks are given in Fig. 13.
5.4 Additional devices connectable to the turnstile
5.4.1 Relay outputs
Connection of control board to relay outputs is done through corresponding contacts of
connector block XT1.H. The following relay outputs are installed:
•ALARM: contacts Alarm 1 and Alarm 2 (see Clause 5.4.2),
•PASS A: contacts Pass A and Common (see Clause 5.2.7),
•PASS B: contacts Pass B and Common (see Clause 5.2.7),
•READY: contacts Ready and Common (see Clause 5.5),
•DETECTOR: contacts Det Out and Common (see Clause 5.4.2).
Contacts Pass A, Pass B and Common are also located on connector block XS1.
Relays have normally open contacts. Therewith common for those relays contact Common
is not connected with the negative of turnstile power supply (galvanically isolated). In initial
(standard) condition with a switched on power supply relay contacts PASS A, PASS B,
READY and DETECTOR are closed (relay coil gets energized), and relay contacts
ALARM are opened (relay coil gets deenergized).
Relay winding energizing can be identified by lighting up of corresponding red LED,
installed on control board near the corresponding relay (see Fig. 5).

5.4.2 ID and siren
Warning!
Installation of intrusion detector inside the turnstile housing is not anticipated.
Intrusion detector is connected to contacts Detector, GND and +12V of connector block
XT1.L of control board. Characteristics of input signals are indicated in sec. 5.2.5. Current
condition of intrusion detector is transmitted on relay output DETECTOR (contacts Det Out
and Common of connector block XT1.H).
Siren is connected to contacts Alarm 1, Alarm 2 and GND and +12V of connector block
XT1.H. Characteristics of relay output signals ALARM are indicated in sec. 5.4.1.
Output activation ALARM takes place, if activation of input Detector takes place with a
blocked rotating mechanism of the turnstile (command «Passage denial» or «Both
directions closed» is issued), i.e. control signal comes from the intrusion detector. Output
ALARM gets stabilized in 5 seconds after activation or in case of any incoming control
command.
Note:
Control signal from intrusion detector doesn’t lead to ALARM output activation,
if the
rotating mechanism of the turnstile is blocked in one of directions or was blocked

5.4.3 Remote indicators
Remote indication blocks for corresponding passage directions is connected to outputs
Light A and Light B. Outputs are provided with the complete group of contacts: normally
opened NO, normally closed NC and common C. Connection to the outputs is done
correspondingly through connector blocks XT4 and XT5.
If the passage in direction A/B is permitted, relay of corresponding passage direction
Light A/Light B gets activated (its winding gets energized), if the passage is denied – it
gets stabilized. Relay winding energizing can be identified by lighting up of corresponding
red LED, installed on control board near the corresponding relay.
Output cascades for the “Light A” and the “Light B” relays are nonbridging relay contacts
(Fig. 10) with the following signal characteristics:
maximum switched voltage .......................................................................... 30 VDC
maximum switched voltage ........................................................................... 42 VAC
maximum switched AC/DC................................................................................... 3 A
closed contact resistance .................................................... no more than 0.15 Ohm

5.5 Operation contingencies and response
Turnstile anticipates an alarm function of standard mode violation in case of unauthorized
passage and in case of late barrier arms resetting to the home (closed) position. Barrier
arms turn is controlled by activation of rotation unit light sensor. Sensor gets activated with
barrier arms turn angle wider than 8 degrees from the home (closed) position.
•Unauthorized access is a rotation of barrier arms without a command to unblock the
rotation unit.
•Barrier arms return to initial position is considered to be delayed if the passage zone
is opened for more than 30 seconds.
In each of indicated cases the activation of switch READY takes place (switch coil is
deenergized), therewith the output contacts Ready and Common get opened (ref.
Section. 5.4.1). When barrier arms reset to home position, normalization of switch READY
takes place (switch coil is energized), the output contacts “Ready” and “Common” get
closed.
Note:
If the optical sensor of barrier arms rotation unit breaks down, the activation of
switch READY takes place as well until the fault is repaired.

6 MARKING AND PACKAGING
The turnstile has a marking sticker on the internal side of the turnstile top cover and a label
– inside, on the rear side of the turnstile housing. The label contains trademark, contact
information of the manufacturer, production date, power-supply voltage, power
consumption. To get access to the marking sticker and the label, open the top cover.
To do so proceed as follows:
1. Switch off power supply of the turnstile.
2. Insert the allen key into the hole in the rear part of the turnstile housing, use it to
unscrew the drag screw (4), unlocking the top cover;
3. Holding the front edge of the top cover (3) carefully lift it and turning it remove it
from the turnstile housing. Be careful not to damage the CLB located under the
cover while removing the top cover.
4. Place the top cover on a flat steady surface.
Installation of the top cover back into its operation position is carried out in reverse order.
After mounting the top cover, return the drag screw into initial position. Turn on the
turnstile power supply.
The turnstile in the original package should be transported in closed freight containers or
other closed type cargo transport units.
