TTR-07.1 Electromechanical Tripod Turnstile
Note:
For generating of a high-level signal at all the input contacts (
Unlock A
,
Stop
,
Unlock B
,
Fire Alarm
and
Detector
) 2kOhm resistors connected to the power supply
bus “+ 5V” are used.
The control element* must provide the following signal characteristics:
* the relay contact as the control element:
minimum switched current ........................................................................max. 2 mA
closed contact resistance
(with the resistance of the connected cable) ...................................... max. 300 Ohm
*the circuit with open-collector output as the control element:
voltage at the closed contact
(low - level signal at the CLB input) ...........................................................max. 0.8 V
5.4.3 The relays PASS A (contacts
PASS A
and
Common
),
PASS B
(contacts
PASS
В
and
Common
),
Ready
(contacts
Ready
and
Common
),
Detector
(contacts
Det Out
and
Common
) and
Alarm
(contacts
Alarm 1
and
Alarm 2
) have normally open contacts. The
“
Common
” contact, at that, is not connected to the CLB power supply negative terminal. In
the initial (inactive) state, when the power is on, the relay contacts “
PASS A
”, “
PASS B
”,
“
Ready
” and “
Detector
” are closed (voltage is supplied to the relay coil) and the “
Alarm
”
relay contacts are broken (voltage is not supplied to the relay coil). The CLB relay
operation/release is indicated by lighting up/going down of the red test indicators located
near the corresponding relays (Fig. 4). The output cascades for
PASS A
,
PASS B
,
Ready
,
Det Out
and
Alarm
are the contacts with the following signal characteristics (Fig 7):
maximum commutation voltage ................................................................................ 42 VDC
maximum switched current ......................................................................................... 0.25 A
closed contact resistance.............................................................................. max. 0.15 Ohm

5.5 Control modes of the turnstile
5.5.1 There are two modes of the turnstile control - a pulse control mode and a potential
control mode. They determine available operating modes
of the turnstile
(Table 2 and
Table 3).
5.5.2 The control mode is set by the jumper on the J1 connector (the J1 connector location
is shown on Fig. 4 and on a label located on the inner surface of turnstile cover (2)): 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.
