Turnstile design
1.4.1.1
The turnstile body is a metalware, which footing
10
(
See Fig.1
) is installed on an even
surface by means of Redibolt anchors. The turnstile status is displayed by LED display boards

1.4.1.2
The control mechanism
5
(
See Fig.1
) is installed at the top of the body. The hub
6
with
barrier rods
7
, securely fixed to its levers by crimping method,
is installed on the control
mechanism shaft. One of three barrier rods is positioned horizontally barring the turnstile access.
1.4.1.3
The plates, on which power supply unit, controllers, terminal blocks for connection to 220
V network and control panel are mounted, are fixed inside the turnstile post
1
(
See Fig.1
) under the
removable door
8
(for the turnstiles CENTURION-M and BASTION-M) or removable lid
4
(for
the turnstiles TWIX and SKULL). Controller controls the turnstile motor analyzing signals from
speed and position sensors as well as provides the motor protection against overloads. Receiving
control commands from peripherals (control panel, ACS etc.) the controller controls LED displays
and generates feedback signals for ACS (Access Control System).
1.4.1.4
The external control panel (
See Annex B
) has the following functions: single entry access,
single exit access; entry locking, exit locking; free entry access, free exit access, panic.
