OVERVIEW Our Barrier Arm Optical Turnstiles monitor through-beam infrared sensors, access control contacts, and arm position sensors to control the motion of the barrier arms mounted in the center of the turnstile housing. The barrier arms are normally extended, and retract into the turnstile housing when a valid card signal is received from the card access system. The barrier arms remain in the retracted position while the person passes through the lane, then are reset to the extended position when the lane is cleared. The card access system is interfaced with the optical turnstile control system. All lane controls and alarms are communicated with relay contacts between the card access system and the optical turnstile system. Lane displays and sounders are also controlled from the optical turnstile control system. One person is allowed to pass through the turnstile lane for each valid card presented. If a person walks through the passageway without presenting a valid card, an alarm is generated. A sounder in the housing alerts area personnel that a violation has occurred, and an alarm relay contact notifies the access control system of the alarm. OPERATION VALID CARD USAGE When a valid card contact is received at the turnstile control the barrier arm retracts into the turnstile housing. The barrier arm swings away from the direction of valid passage. After the person passes through the turnstile lane and all IR sensors are cleared the barrier arm resets to the extended position. FREE EXIT MODE The optical turnstile system has two operating modes - CARD IN / CARD OUT and CARD IN / FREE EXIT. When the system is in FREE EXIT MODE, the sensors at the secured end of the turnstile lane determine that a person is exiting and the barrier arm retracts into the turnstile housing to allow exit passage. The barrier arm is reset to the extended position after the person passes through the arm movement area. TAILGATE ALARM When the optical turnstile system detects a tailgate violation, the barrier arms are sent to the extended position after the first person passes through the arm movement area. Multiple IR sensors are positioned throughout the lane passage area so that a tailgate violation is determined prior to the violating person reaching the arm movement area. ARM BYPASS The barrier arm operation may be bypassed with a contact from the card access system to allow for optical turnstile operation without arm operation. The barrier arms retract into the turnstile housing until the arm bypass contact is reset. The optical turnstile continues to operate normally. EMERGENCY OPERATION An emergency override contact from the card access or fire alarm system will cause the barrier arms to be retracted into the turnstile housing, and the motion control system will be disabled so that the barrier arms cannot be extended into the lane passageway.
