PART 2 PRODUCTS

2.1 TURNSTILE

The basis of design product required product is Alvarado MST-6X Full Height Security Turnstile. No other alternative products will be accepted.

Provide product information and shop drawings for Government Review.

2.1.1 Construction

A. Top Channel:

1. The top channel frame shall be a 7" wide U-frame fabricated from 4-gauge steel, powder-coated in a zinc rich powder coat.

2. The top channel cover system shall slide apart horizontally, providing access to the interior of the top channel without having to lift the cover vertically when opening. The top channel cover shall be fabricated from 16-gauge, #304 stainless steel, regardless of turnstile finish.

B. Yoke (Curved Section):

1. The yoke (curved section) shall be an all welded single assembly, not multiple assemblies bolted together. It shall consist of 10 pieces of vertically aligned 1 3/4" OD 16-gauge steel tubing notched and welded to two curved, horizontal tubes. Two 3/16" x 1" steel straps shall be welded to the outside of the ten tubes for support. No external fasteners shall be used in the fabrication of the yoke section.

2. Two card reader plate receivers shall be welded to either side of the yoke.

C. Roto (Rotating Section):

1. The roto (rotating section) shall be an all welded single assembly, not multiple assemblies bolted together. It shall consist of three vertical groupings of arms, with each arm notched and welded vertically to a vertical 3" x 3/16" wall tube. Each grouping of arms shall be positioned 120 degrees apart from one another and shall consist of 13 arms (39 total arms per roto). Each arm shall be 14-gauge, 1 3/4" OD steel tubing. Arms shall have either welded metal caps (powder coated or stainless steel models) or ribbed, force-fit plastic caps (galvanized models). No external fasteners shall be used in the fabrication of the roto section.

D. Bottom Bearing Assembly:

1. The bottom bearing assembly shall consist of a sealed inter-ring bearing, a bearing shaft which fits into the underside of the roto, and bottom bearing housing and cover.

E. OV (Barrier)

SECTION 11 14 00 Page 2

1. The OV (barrier section) shall be an all welded single assembly which prevents passage in the reverse direction. It shall consist of 13 arms notched and then welded to a 3" OD x 3/16" wall steel vertical tube. The arms shall be constructed from 1 3/4" OD x 14-gauge #304 steel tubing.

Arms shall have either welded metal caps (powder coated or stainless steel models) or ribbed, force-fit plastic caps (galvanized models). No external fasteners shall be used in the fabrication of the OV section.

F. Yoke Guard Plate

1. The yoke guard plate is a single piece of 16-gauge steel that bolts to the underside of the top channel assembly and the top of the yoke.

2.1.2 Equipment

A. General: The turnstile shall provide electric lock control in both directions. Upon receipt of an authorization signal from an access control system or a push button device, the roto will unlock and allow a single user to pass through the turnstile in the direction requested. The turnstile will reset after the user has passed through the turnstile or within 20 seconds if passage does not occur.

B. Mechanical Operation:

1. Roto / Top Channel Connection: The connection between the roto and the top channel shall be accomplished through the use of a multiple grooved splined shaft and coupling.

2. Turnstile Locking / Unlocking: A solenoid/spring assembly shall move the lock arms into the "locked" or "unlocked" position. Each lock arm shall be controlled independently to allow bi-directional control.

3. Top Bearings: The top bearings shall be fully concealed from view by a cover fabricated from #304 stainless steel material.

4. Self-Adjusting Speed Control / Self-Centering: The turnstile shall have self-adjusting speed control which automatically increases or decreases resistance depending on the pushing force of the user. The turnstile shall also self-center, automatically returning to the "home" position after rotation. Self-centering shall be controlled. When lock arms are disengaged, the turnstile shall rotate only once when the roto is spun with force. A roto that self-centers through spinning and settling is not acceptable.

C. Electrical Operation:

1. The turnstile top channel shall contain a fused junction box into which the installer wires primary power (110VAC or optional 220VAC).

2. The power junction box shall contain an on/off switch. When the switch is in the "on" position, a green LED shall illuminate on the turnstile controller.

3. A UL-rated transformer shall be joined to the junction box and shall step down the primary power to low voltage, 12VDC operation.

4. The turnstile shall be fail-lock in the entry direction, and fail-safe in the exit direction.

5. Solenoids shall be continuous-duty rated and shall be activated using a firing current of 12VDC and held in place using a lower holding current of approximately 6VDC. The purpose of the lowered holding current is to reduce overall power consumption of the turnstile and to lengthen the life of the solenoids.

6. The turnstile shall have key overrides allowing the operating technician to override the access control system and unlock one or both directions of the turnstile. Key overrides to be installed in the bottom of the top channel, one for each direction of operation.

7. Electrical operation of the turnstile shall be tested and approved by

SECTION 11 14 00 Page 3

Los Angeles Testing Laboratories.

D. Turnstile Control:

1. The turnstile shall have a microprocessor-based turnstile controller which shall be conformal coated to provide protection against environmental damage.

2. All inputs and outputs of the controller shall be opto-isolated to provide significant protection from power surges, electrical noise, ground loops, and damage from remote lightning strikes.

3. The turnstile shall accept a momentary dry contact activation signal of 1 second or less.

4. Once the turnstile is activated (unlocked) the user is allowed a defined time to pass through the turnstile after activation, before the turnstile automatically relocks. The turnstile shall ship with a default setting of 20 seconds. Additional settings of 5, 10 and 15 seconds shall be user selectable through dip switch settings on the turnstile controller.

5. When a rotation of the turnstile occurs, rotation shall be detected by an electrical opto-interrupter. No mechanical microswitches shall be used in the operation of the turnstile.

6. Upon rotation, the turnstile shall provide a momentary dry contact output to signify a rotation has occurred. The dry contact is provided as a "feedback" signal that a passage has occurred. One output per rotation direction.

7. The turnstile shall have two solenoids, one per direction of operation.

8. In the event the turnstile needs to be converted from fail-safe to fail-lock, or vice versa, it shall be possible to convert the turnstile from fail-safe to fail-lock and vice versa without removing the top channel.

9. The turnstile shall have two test buttons, one per direction of rotation, that simulate the control system interface signal. The purpose of the test buttons is to provide the installer a simple method of troubleshooting by isolating turnstile functionality from the activation system.

10. It shall be possible to maintain either rotation direction in a continuous unlocked state through the application of a sustained dry contact that is independent from the standard "unlock" activation signal.

2.1.3 Finishes

Hot-Dip Galvanized (Model MST-6XGL): All exterior components, except the top channel cover and top and bottom bearing covers (which are #304 stainless steel) are hot-dip galvanized to ASTM Standard A 123/A 123M-02.

2.2 SECURITY ACCESSORIES

I. Card Reader Attachment Plates: Provide and install 6" x 6" card reader attachment plates allow the attachment of the majority of card readers used.
