TTD-08A Electromechanical Box Tripod Turnstile

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.
