5.5 Operation contingencies and response
Turnstile anticipates an alarm function of standard mode violation in case of unauthorized
passage and in case of late barrier arms resetting to the home (closed) position. Barrier
arms turn is controlled by activation of rotation unit light sensor. Sensor gets activated with
barrier arms turn angle wider than 8 degrees from the home (closed) position.
•
Unauthorized access is a rotation of barrier arms without a command to unblock the
rotation unit.
•
Barrier arms return to initial position is considered to be delayed if the passage zone
is opened for more than 30 seconds.
In each of indicated cases the activation of switch READY takes place (switch coil is
deenergized), therewith the output contacts Ready and Common get opened (ref.
Section. 5.4.1). When barrier arms reset to home position, normalization of switch READY
takes place (switch coil is energized), the output contacts “Ready” and “Common” get
closed
.
Note:
If the optical sensor of barrier arms rotation unit breaks down, the activation of
switch
READY takes place as well until the fault is repaired.
