Waist High Optical Turnstile, Barrier Wings
This turnstile has a substantial, authoritative profile that works well in large lobby or entrance areas. The hand polished exterior satin stainless cladding is set off beautifully by the turnstile’s black solid surface acrylic lid. Alternate lid colors are a popular option depending on the specific lobby architectural concerns and colors. Logos can be etched on the clear panels for a corporate look and identity.
In normal operating mode, when a valid credential is presented, the clear barriers quickly retract into the cabinet in approximately .25 seconds, creating a clear passageway for the user and rapidly opening. As the user passes through the turnstile, the barriers either smoothly return to the closed position (ready for the next valid credential) or, if another credential has been presented, the barriers remain open for the next users’ passage.
The barrier panels are controlled via brushless DC motors through closed loop position control that monitors panel position every 1/1000 of a second. The panel movement is quick, precise and constantly monitored for utmost safety.
Illuminated status icons on the lid and audible sounds prompt users, and provide clear notification of card status. The various alarm conditions (e.g., unauthorized entry; loitering in lane; tailgating, etc.) are differentiated by light flashing patterns and through the use of sounds which differentiate depending on the type of alarm. It comes with standard sounds or users can substitute their own custom audio sounds.
To further enhance throughput, the turnstile supports “stacking” of valid entries, meaning the turnstile can queue multiple valid entries without requiring the panels to cycle after each individual patron passage. Additionally, if a subsequent valid credential is presented during the barrier panel closing cycle, the arms stop in mid-cycle and immediately reopen; users do not need to wait until the opening/closing process completes. Depending on the application and response time of the access system used, traffic of up to 40 persons a minute can be reasonably expected.
The turnstile can provide controlled operation in both directions (card in/card out). The turnstile can also provide controlled entry with free passage exit for applications where users are not required to “credential out" for exit. In free passage mode, users can walk directly into the passage lane at a normal pedestrian pace and the panels will automatically open without requiring the user to slow down.
This optical turnstile is also highly effective at deterring and detecting unwanted entry. It's sophisticated detection technology detects unauthorized access attempts and "tailgating" behind an authorized user. Lower crawl sensors detect crawl under attempts. In the event of an invalid entry or exit attempt, the turnstile lights and sounds notify the user and alert attendants. Additional notification outputs are also provided, allowing integration with remote alarms, door locks, CCTV or other devices.
The turnstile also has a number of safety features. Multiple sensors and sophisticated detection algorithms prevent panels from closing on people. In addition, the turnstile has a dedicated emergency input for fire/life safety. If the emergency input is triggered (e.g. via fire alarm system), the barrier panels retract to allow free egress. In addition to fire input, it also allows panels to be pulled open with an adjustable amount of force. In the event the panels are broken away, barriers automatically return to the “home” barrier down position.
The turnstile easily integrates with nearly any access control system. Each side of the turnstile allows interior (under the lid) installation of a mullion-sized proximity reader at each end of the turnstile. Larger readers can be accommodated on top of the lid or on a nearby pedestal. It also has a dedicated single–time entry override input that allows simple integration of a visitor management system and/or the implementation of a guard station push button.
