OVERVIEW Our Medium Housing Optical Turnstile System (OTS-MH) monitors through-beam infrared sensors, access control contacts to determine and annunciate the status of a secured pedestrian walkway. The access control system provides valid card contact closures to the optical turnstile system when a card is presented to the card reader mounted at the turnstile housing. Green and red backlit display indicators prompt persons using the turnstile passageway to present their card, and that access is granted or denied. A sounder located inside the turnstile housing provides a short audible indication that access is granted. One person is allowed to pass through the optical turnstile lane for each valid card presented. If a person walks through the turnstile passageway without presenting a valid card, an alarm is generated. A sounder in the turnstile housing alerts area personnel that a violation has occurred, and an alarm relay contact notifies the access control system of the alarm. STANDARD SYSTEM INTERFACE The lock output of the card access system is monitored by the optical turnstile system to determine when a valid card has been presented. The lock may be fail safe or fail secure. The lock output must be configured for automatic re-lock when the door is opened. The normally closed-door mimic relay (DMR) is monitored by the card reader system. The normally closed alarm relay is monitored by the card reader system. OPERATION NORMAL ENTRY USING CARD READER The DMR opens when the valid card is presented to the card reader, and closes when a person walks through the optical turnstile passageway. This relay cycle is expected by the card reader system and an authorized passage is registered in the card reader database. TAILGATE ALARM If a person walks through the turnstile passageway in the entry direction without presenting a valid card, then the DMR opens again and the card reader system interprets that action as a forced door and an alarm is registered in the card reader database. The optical turnstile system circuit activates the local sounder so that the alarm is annunciated at the door. The normally closed alarm relay opens. The alarm is reset after about 4 seconds. FREE EXIT When a person walks through the turnstile passageway in the exit direction no alarm is generated. Technical Specifications |
