Assembly and Operation Manual

If while the turnstile is in a locked state (in the “Always locked” mode or in the “Both
directions locked” mode, Tables 3 and 4) a signal from the intrusion detector comes,
the “Alarm” signal is generated, which is disabled either after 5 sec. or after execution of
any received command. The signal from the intrusion detector is ignored for the period of
authorized unlocking of the turnstile in either or both directions.
A signal coming from the intrusion detector within 3 sec. after the “Always
locked”/“Both directions locked” mode is set, is ignored.
A signal on current status of the intrusion detector is constantly transmitted to the
“Det Out” and “Common” contacts of the CLB “XT1.H” connector block (Fig. 3).
6.9.3 The emergency unblocking device is connected to the “XT1.L” connector
block of the CLB in accordance with the connection layout (Figure A.1
Appendix A and Figure 3). If the “Fire Alarm” input is not used, it is
necessary to install a jumper between the contacts “Fire Alarm” and
“GND”. This jumper is installed at delivery.
Operation of the turnstile under commands of the emergency unblocking de-
vice:
6.9.3.1 In the pulse control mode, when a low-level signal is removed from
the “Fire Alarm” input, both passage directions open for the whole
period of the signal absence. Other control commands are ignored at
that. When the low-level signal appears at the “Fire Alarm” input, the
turnstile turns to the “Always locked” mode.
6.9.3.2 In the potential control mode, when a low-level signal is removed from
the “Fire Alarm” input, both passage directions open for the whole pe-
riod of the signal absence. Other control commands are ignored at
that. When the low-level signal appears at the “Fire Alarm” input, the
passage directions turn to the mode in accordance with the signal le-
vels at the inputs “Unlock A”, “Unlock B” and “Stop”.
6.10. Unblocking with a mechanical release key
Mechanical release function is intended for unlocking barrier arms ensuring free ro-
tation in case of emergency, or at a power supply failure.
To unlock the turnstile with a mechanical release key proceed as follows:
Insert the key into a mechanical release lock (7);
Turn the key clockwise till it stops (open the lock, the lock cylinder will move out
at this);
Return the key into its reset position and take it out of the lock;
Make sure the TB-01 turnstile is unlocked by turning the barrier arms in both
direction several times;
To mechanically lock the TB-01 turnstile:
Install the barrier arms in their home position;
Press the lock cylinder into lock case till it clicks (without the key);
Make sure the turnstile is locked and the barrier arms cannot be free rotated
manually.
6.11. Operation contingencies and response
6.11.1 The turnstile is capable of providing information on the following
operation contingencies:
unauthorized
access;
passage delay for more than 30 sec.;
one or both optic sensors are out of order.
