TTR-04CW Electromechanical Tripod Turnstile
5.10 Key override control
5.10.1 The key override option allows an operating technician to unlock both directions of
the turnstile if there is need to override the access control system or in case of emergency
or power failure.
5.10.2 To unblock the turnstile it is necessary to insert the key (14) into the lock (15), turn it
at 90° clockwise and then take out. Then the barrier arms can be freely turned in both
directions.
5.10.3 Deactivating mechanical unblocking of the turnstile in the following order:

install barrier arms to the starting position;

click on the lock mechanism mechanical release, sinking it into the housing until it
clicks;

make sure that the turnstile is locked, and the barrier arms do not rotate in any
direction.
5.11 Operation contingencies and response
5.11.1 The turnstile is capable of providing information on the following operation
contingencies:

unauthorized access;

passage delay for more than 30 sec;

one or both optical arm rotation sensors are out of order.
A special signal “Ready” is generated in each of the above cases.
5.11.2 2 In case of unauthorized access the “Ready” signal is formed as follows: at 8°
arm rotation one of the optical sensors (Fig. 1
3
) responds and the output contacts Ready
and Common get broken (the beginning of the signal). When the barrier arms reset to
home position, the both optical sensors become passive and the output contacts
Ready and Common get closed (the finish of the signal).
5.11.3 In case of delay of an authorized passage for more than 30 sec. the signal “Ready”
is formed as follows: if within 30 seconds from the moment of passage commencing, which
is determined by the arm rotation at no less than 8° (i.e. activation of one of the optical
sensors), the reset of barrier arms to home position does not happen, the output contacts
Ready and Common break (the beginning of the signal). When the barrier arms reset to
home position, the both optical sensors become passive and the output contacts Ready
and Common are closed (finish of the signal).
5.11.4 When one or both of the optical sensors become out of order, the output contacts
Ready and Common get broken (the beginning of the signal “Ready”). After fault removal
the closed status of the contacts Ready and Common is renewed.
