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.

(for the turnstiles TWIX
-
M TWIN). 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)

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.
