OPTICAL TURNSTILE SYSTEMS Barrier Arm Turnstiles Model No. OTS-ARM OVERVIEW The OTS-SS-ARM monitors through-beam infrared sensors, access control contacts, and arm position sensors to control the motion of the barriers or arms mounted in the center of the lane housing. The arms are normally extended, then retract into the lane housing when a valid card signal is received from the card access system. The 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. FEATURES CARD IN / CARD OUT OPERATION DAY / NIGHT MODE ARM BYPASS MODE ANTI-CRAWL SENSORS SAFETY SENSORS TO PREVENT BARRIER MOTION WHILE A PERSON IS IN THE BARRIER MOVEMENT AREA BACKLIT DISPLAY INDICATOR GRAPHICS AUTOMATIC ALARM RESET TAILGATE SENSITIVITY FIELD ADJUSTABLE DURABLE STAINLESS STEEL CONSTRUCTION FOOTPRINT: 10 X 60 X 38 INCHES BRUSHED STAINLESS STEEL FINISH SPECIALTY FINISHES AVAILABLE Model Shown: 60 Stainless Steel, Single Arm Units, Beveled Ends One person is allowed to pass through the walkway 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 lane control, the arm retracts into the lane housing. The arm swings away from the direction of valid passage. After the person passes through the lane and all IR sensors are cleared the 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 lane determine that a person is exiting and the arm retracts into the lane housing to allow exit passage. The arm is reset to the extended position after the person passes through the arm movement area. Kouba & Associates, Inc. 4040 FM 535 Bastrop, Texas 78602 Phone: 512.303.5033 Fax: 512.321.4692
TAILGATE ALARM When the optical turnstile system detects a tailgate violation, the 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 arm operation may be bypassed with a contact from the card access system to allow for optical turnstile operation without arm operation. The arms retract into the lane 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 arms to be retracted into the lane housing, and the motion control system will be disabled so that the arms cannot be extended into the lane passageway.

TURNSTILE MOUNTING CAUTION: The units weigh approximately 280 pounds. 6. Position the units at the installation location using a chalk line to ensure proper alignment. If the units were custom designed for a specific application then space turnstile as required for application. If standard units, we recommend that spacing between the turnstiles be 30 to 32 inches for standard walkways and for ADA designated walkways 36 to 38 inches. Please take into consideration that at least one walkway should accommodate ADA requirements. Mark the position of each turnstile. ATTENTION: Each of the housings require Eight (8) 3/8 x4 1/2 threaded rods to sufficiently attach the housings to the floor. DO NOT USE SMALLER ANCHORS TO MOUNT THE HOUSINGS. Failure to use the correct size and number of anchor bolts will void the manufacturer s warranty. 7. Refer to Housing Installation Instructions for detailed anchoring and leveling procedures. WIRE REQUIRMENTS Refer to the system level-wiring diagram for site specific cabling requirements. The housings with the lane electronics and card readers will require: 3 conductor 14 AWG minimum for 120 VAC Power to each housing 16 conductor 22 AWG minimum for interface to the access control system 8 conductor shielded 22 AWG minimum housing to housing motor control only for adjacent lanes with motors 2 conductor 18 AWG minimum housing to housing motor brake control only for adjacent lanes with motors Card Reader cable from Card Access System to each housing Elevator Display cabling from Access Control System WIRE TERMINATIONS Refer to the system wiring diagrams for exact terminations and signal definitions. The valid card signal is to be connected to the card reader lock output relay. The lock output relay must be configured for 1 second maximum contact duration or for automatic relock when the door is opened. The door-input circuit of the card reader system should be connected to the entry acknowledge or exit acknowledge relay output on the lane control panel. The entry acknowledge or exit acknowledge relay output operates as a door mimic operation. The relay closes when a person walks through the lane, and re-opens when the lane is clear. The card reader system detects that relay cycle as a normal door unlock and open sequence. If a person walks through the lane without a valid card, then the relay closes. The card reader system detects that relay closing as a forced door. Kouba & Associates, Inc. Phone: 512-303-5033 4040 FM 535 Page 2 Fax: 512-321-4692 Bastrop, Texas 78602
Inputs: Entry Card (momentary) Input this input is activated by the access control system to allow a valid entry passage through the lane. The access control system lock relay should be configured to provide a maximum 1 second pulse to this input or return to an open state after the system monitors the entry acknowledge relay changing state. Exit Card (momentary) Input NOT USED IN THIS APPLICATION Invalid Card (momentary) Input this input is activated by the access control system to notify the card holder that their badge was read but access is denied. The card holder is alerted to the status by the flashing red LED arrays mounted under the glass and a distinctive chime. Bypass (maintained) Input this input can be activated by the access control system or from a remote switch. When activated the arms retract and both LED arrays mounted behind the glass illuminate green. In this condition the unit will not alarm if individuals pass through the lane. Fire Alarm (maintained) Input this input is intended to be activated from the fire alarm system. When activated the unit retracts the arms and allows free passage until the fire alarm is reset. Outputs: Alarm Relay activates when an invalid passage through the lane occurs. Invalid Card Relay is enabled when an invalid input activates. Arm Fault Relay - activates when the arm is out of position. Exit Acknowledge Relay activates when an exit passage is detected by the unit whether the passage is valid or an alarm condition has occurred. Entry Acknowledge Relay is enabled when an entry passage is detected by the unit whether the passage is valid or an alarm condition has occurred. OPERATION VERIFICATION 1. INITIAL POWER UP: Make sure that the Valid Card output is open. Apply 120 VAC to the power input to the local housing (If remote housing is used, always apply power to it prior to applying power to the local housing); this will power up the control board and the sensors. The arms will begin to move automatically and will stall at each end of the turnstile and then proceed to the center of the housing. This is the homing sequence and it should not be interfered with. If the arms are stalled prematurely from someone or something stopping them, the sequence will have to be restarted by a power off and on sequence. Once both arms are centered (Normal Position) the unit will beep and enter its normal state as long as all inputs are correct. 2. SENSOR TEST: Each infrared Transmitter has one Red LED. The infrared Receiver has 2 LED s on each Receiver. The Green LED indicates powered up and aligned, the Red LED is illuminated when the sensors are misaligned or beams are blocked. 3. FIRST WALK TEST: The Red PRESENT CARD indicator on the top should be illuminated. Walk into the sensing area from the entry side. The unit should provide an audible sounder, alarm, entry acknowledge relay should activate and the arm(s) should lock in place. Then walk through the unit in the Kouba & Associates, Inc.

exit direction (Free Exit). The unit s barrier arms should open away from the path of travel and the exit acknowledge relay should activate. When the lane is clear, the arms should return to the closed position. 4. SECOND WALK TEST: Present a valid card at the reader and ENSURE the valid card input contact CLOSED. The Green PROCEED indicator on the display should illuminate and the barrier arms should open away from the path of travel and the unit s entry acknowledge relay should activate. Walk through the unit and the indicator lights should return back to illuminating red and the barrier should close. 5. THIRD WALK TEST: Present a valid card to the reader, and have two people walk through the sensing area close together. An alarm should be generated. Repeat this several times varying the distance between the two people. At some point of closeness, an alarm will not be generated. The tailgate sensitivity adjustment is provided to set the alarm distance between people. 6. ADJUSTMENTS - Refer to the photo of the control board for the location of the adjustment delays. The Tailgate sensitivity adjustment is used to allow purses, bags, umbrellas, etc to be carried through the sensing area without generating a false alarm, while maintaining a valid level of tailgate monitoring. This adjustment can be set for very sensitive tailgate detection, which can cause false alarms when bags and other objects are carried through the sensing area. Or this adjustment can be set for loose tailgate detection, which can allow someone to follow a person through the sensing area without generating an alarm. Maximum sensitivity is with the pot set toward the programming jumpers or counterclockwise. Minimum sensitivity is with the pot set away from the jumpers. The pot has a 180-degree turn of rotation. FINAL ASSEMBLY After the turnstiles are mounted and system operation is verified, remove the remaining protective covering from the side panels and install back on the corresponding turnstiles. The panels are not interchangeable, minor factory adjustments were made to ensure proper fit to each housing. CLEANING The lanes may be kept clean by using any household or industrial grade stainless steel and window cleaner.

6. Epoxy Application: (refer to DATASHEET - Anchoring Epoxy High Strength 8620-31 for more detailed product information and instruction) Approved Epoxy Commercial Grade Quikrete High Strength Anchoring Epoxy Product No. 8620-31 Use a heavy duty professional caulking gun. Remove plastic cap and plugs from the cartridge. Save for closing cartridge (match white to white). Attach mixing nozzle to cartridge. Discard a small amount of gunned product until uniform color is achieved. Mixing nozzle will harden in approximately 20 min if not in use, and must be discarded. Dispense the epoxy at the bottom of the hole while withdrawing nozzle. Dispense epoxy (by filling 5/8 of hole) so that once threaded rod is inserted, the hole is completely full. Repeat for each hole before moving on to next step. Remember: Epoxy has a 20 minute working time. 7. Move housing into place over drilled/epoxied holes and in line with placement markings. Use 3/8 x4 ½ threaded rod with nuts and rectangle washers (Kouba Systems supplied) already installed and insert them into the bottom each hole while turning the rod clockwise. Remove any excess material immediately. Leave anchors undisturbed for a minimum of 4 hours (at 77deg F or longer for colder temperatures) to allow epoxy to harden. DO NOT TIGHTEN NUTS UNTIL EPOXY HAS HARDENED. DO NOT USE ROUND WASHERS ATTENTION: Each of the housings require Eight (8) 3/8 x4 1/2 threaded rods to sufficiently attach the housings to the floor. DO NOT USE SMALLER ANCHORS TO MOUNT THE HOUSINGS. Failure to use the correct size and number of anchor bolts may void the manufacturer s warranty. 8. After epoxy has hardened, tighten nuts to secure housing flush to the floor. DO NOT PLACE SHIMS BETWEEN FLOOR AND HOUSING TO LEVEL.
