2. Optical Turnstiles

2.1. General description: The optical turnstile system shall monitor and be able to restrict pedestrian traffic between public and secure areas. Each turnstile lane shall use an array of optical sensors to determine the number and direction of persons passing through the lane. Each turnstile shall be able to authorize passage to persons presenting a valid electronic security card (or other authentication device). Turnstiles shall be compatible with the building access control system. Barrier style turnstiles shall feature retractable or collapsible barriers to block the pedestrian’s path.

2.2. Physical description:

2.2.1. The optical turnstile system shall be composed of barrier free or electrically controlled retracting or collapsible barrier type optical turnstiles permanently mounted to floor.

2.2.2. The first and single lanes shall consist of the main detection and activation unit.

2.2.3. Subsequent units (“interlanes”) shall integrate the control, detection and lighting systems so that the total number of units (turnstile cabinets) for a series of lanes in one location shall be equal to the number of lanes, plus one.

2.3. Appearance:

2.3.1. Each unit’s structure shall be made of 6061 T6 Aluminum.

2.3.2. Each unit may be optionally housed in a brushed #4 SS401 stainless steel housing with dimensions determined by the customer’s choice of decorative trim.

2.4. Detection sensors:

Design of the unit shall feature at least 16 optical sensors.

2.4.1. Each sensor shall be composed of a separate transmitter and receiver; no reflectors shall be used.

2.4.2. Each sensor shall resist interference from natural and indoor lighting.

2.4.3. Each sensor shall use pulsed beams (beams that rapidly turn on and off) to allow perfect operation in direct sunlight and so as not to be fooled by a flashlight

2.4.4. Sensors shall be deployed in a matrix configuration, such that each optical receiver shall detect the beams from several optical transmitters; the optical detection matrix shall offer at least 128 detection beams.

2.4.5. Sensors shall be deployed at two different heights to be able to defend against people trying to roll/crawl through the lane without being detected; there shall be sensors at approximately ankle height and waist height

2.5. State control:

2.5.1. The turnstile shall be bi-directional, allowing traffic in both directions. Each direction may be in one of three states: Free passage: all persons are authorized to pass under all conditions Card access: each person must present a valid security card or other authentication means to the card reader before being authorized to pass Lane closed: no persons are authorized to pass, and security cards are ignored

2.6. Card readers:

2.6.1. Design of unit shall accept card readers or other authentication means that provide a normally open momentary contact.

2.6.2. For all models with the exception of the counting lane model, there shall be space for two card readers per lane (one for each direction)

2.6.3. Lane authorization in one direction will lock-out authentication (or passage) the other direction.

2.7. System integration:

2.7.1. The design of the units shall provide a minimum of 8 dry contact inputs and 3 dry contact outputs (each selectable as either a normally open or a normally closed contact) including: card reader input, entry & exit lane open input, entry & exit guard authorized access input, entry & exit, lane in service, barrier free input

2.7.2. The design of the units shall provide three separate outputs for: common alarm output, auto (timed) reset passage completed (counter output), entry & exit

2.7.3. Signaling alarm buzzer (tailgating, beam blocked, wrong-way, unauthorized passage, etc.) end and top lights to indicate lane status (lane open amber, lane closed red, access granted green, alarm flashing red)

2.7.4. Each unit shall accept guard shunt inputs to permit remote release (by authorized personnel); this would typically be wired to a pushbutton at the guard desk to allow a site visitor to enter without a badge and without generating an alarm. When the input contact is closed momentarily, the turnstile will open the lane for a single person to pass in one direction without presenting a badge.

2.7.5. Each unit shall signal the passage of a pedestrian in each direction (in/out) by generating a dry contact closure for the access control system (passage completed/counter output).

2.7.6. Each unit shall signal trouble with the unit by all flashing red.

2.7.7. Each dry contact input shall have a corresponding LED to show the status of that contact input (for debugging purposes); the LED shall turn on when the contact input is closed.

2.7.8. It shall be possible to control the turnstiles (set free passage/card access/lane closed mode, manually authorize access for a single person) by all of the following methods: from the access control system (via relays) from a desktop-mounted control panel (supplied by others)

2.7.9. It shall be possible to control “integration parameters” . Independently configurable parameters shall include: the total length of the audible & visual alarm, in seconds the length of time to allow a beam to be blocked before generating an alarm the length of the door contact pulses generated when people walk through (hidden function)

2.8. User interface:

2.8.1. Design of the unit shall feature colored lights on the ends of the turnstiles. The lights shall appear on the right-hand sides of each lane in each direction; thus, each lane will have an end light at right corner. Amber shall mean unit ready to accept user card. Green shall mean acceptance of card and permission granted to proceed. Red shall mean that the lane is closed/disabled. Flashing red shall indicate an alarm or system fault.

2.8.2. The unit shall feature lighted pictogram indicators on the horizontal top & end surface of the turnstile. Lights shall use LEDs. A green arrow light shall appear when the person may walk through (i.e., when their card has been accepted, or when the lane is in free passage mode). A red “X” “do not enter” symbol shall appear when the lane is closed, and shall flash when an alarm occurs. An amber color light shall appear when the lane is ready to accept a card reader signal.

2.9. Accessibility:

2.9.1. All lanes specified as such shall comply with ADA regulations.

2.9.2. The length and the shape of the housing shall be designed to comply with ADA while maintaining a minimum 36” lane width.

2.9.3. The turnstile shall detect and disregard guide dogs (i.e., the turnstile shall not generate an alarm when an authorized user walks through accompanied by a guide dog).

2.9.4. The turnstile shall detect and disregard wheelchairs (i.e., the turnstile shall not generate an alarm when an authorized user rolls through in a wheelchair).

2.10. Performance and reliability:

2.10.1. Each turnstile shall provide a throughput of 25 people per minute, provided that the delay from card access system to access granted signal is less than 0.5 seconds.

2.10.2. Design of the unit shall provide for the sensing of “tailgating” of detecting pedestrians walking with a minimum following distance of 6mm (1/4″). Detection of tailgating shall trigger the alarm.

2.10.3. The unit shall use no moving parts outside the barrier mechanism.

2.11. Alarms:

2.11.1. Design of the unit shall feature the activation of an alarm and signal to the security system (via a relay contact closure), with automatic reset to “ready” mode after an adjustable time period. There are simultaneous audible and visual alarms (flashing lights) on the turnstile.

2.11.2. The unit shall trigger an alarm if the lane is blocked longer than a period of time (which shall be adjustable).

2.11.3. The turnstiles shall be fault tolerant: The turnstile shall, in most cases, detect and discern common objects carried by people, and will avoid generating alarms for: wheeled carry-on size suitcases (pushed in front of or pulled behind the person), briefcases, purses, book bags, canes, umbrellas. The unit in most cases, shall be able to detect, discern, and avoid generating alarms for common objects while still offering ¼” tailgate detection. The turnstile shall not generate an alarm if only a single beam is broken. The turnstile shall not shunt any sensors during the passage; all detection beams shall remain active at all times.

2.12. Barrier configuration: The retractable barriers shall be normally closed (blocking passage through the lane), unless released by the fire alarm system.

2.12.1. Barriers shall be prevented from activation in the event that deployment could strike and or injure the pedestrian (or activating the barrier free input).

2.12.2. Barriers motors shall reverse immediately if the barriers encounter physical resistance while moving.

2.12.3. Barriers shall automatically return to the normally closed position after the last sensor has been cleared by a user.

2.12.4. Turnstiles shall be designed to immediately enter to the barrier free mode upon activation of the fire alarm system and/or power failure. When the fire alarm input is triggered, the turnstile shall open barriers in both directions. When power is lost, the drop arm barriers shall automatically retract, solely by mechanical means. Door units will be free to be manually moved out of the way without resistance.

2.13. Design of the barriers:

2.13.1. Door type units shall consist of two barriers per lane, with each barrier blocking approximately half the width of the lane

2.13.2. Drop arm type shall consist of either one (standard lane) or two (for ADA width lanes) barrier(s).

2.13.3. Each door barrier shall consist of tempered glass panels that meet ASTM C1048 spec. When opening, the barriers shall move away from the direction of travel and into the turnstile, such that, when fully open, the barriers shall not encroach upon the traffic area.

2.13.4. Each drop arm barrier shall consist of an aluminum bar that pivots about a point near the top of the turnstile; when opening, the barriers shall move downward and into the turnstile, such that, when fully open, the barriers shall not encroach upon the traffic area

2.13.5. The barriers shall be normally-closed in operation; the barriers shall open to permit a person to pass, and shall close as soon as the person has cleared the optical beams.

2.13.6. It shall be possible to disable the barriers on-the-fly; in such a case, the barriers shall retract into the turnstile, and the turnstile shall behave as a barrier-free turnstile.

2.13.7. The barrier shall be powered by a motor, the barrier shall be able to open or close in less than 1s, provided no safety sensors are obstructed. The barrier and motor shall be designed for a 100% duty cycle (continuous operation—running at a constant throughput of 25 people per minute, 24 hours a day, 7 days a week)
