Important Electrical Information
Installation of the control head mechanism into the turnstile requires a grounding-type
outlet receptacle installed inside of the frame or cabinet through the provided conduit
access points.
To reduce the risk of electric shock, this equipment has a grounding type plug that has a
third (grounding) pin. This plug will only fit into a grounding type outlet. If the plug does
not fit into the outlet, contact a qualified electrician to install the proper outlet. Do not
change this plug in any way.
Additionally, the MS2-H50 power supply from this appliance must be grounded to the
frame of the turnstile. Utilize the green colored grounding screw threaded into the
grounding tab located near the power supply along with the provided grounding wire from
the power supply to ensure the equipment is proper grounded.

Full Height Turnstile Rotor Alignment
Mounting a new 6500 series control head is very simple. Unbolt the existing control head from
whatever turnstile it is installed in and mount the new one in its place. The control head is backwards
compatible with nearly every turnstile we have ever made on its own. In units that the hole pattern does
not match, an adaptor plate is provided to make installation just as simple.
Full height turnstiles have one extra step involved when installing the control head. It is crucial
that the rotor is aligned properly or the head will not function as intended. One set of arms on the rotor
must rest in between the two half-moon shaped yoke assemblies on the turnstile. Refer to the diagram
below as a visual guide to help install the control head into the rotor properly.
Note: Failure to align the rotor on a full height turnstile properly will cause inconsistent
operation and may even physically trap someone inside of the turnstile.
See the next page for more detailed instructions for mounting the control head.

6500 Series Control Head Installation
To reduce the risk of electrical shock, do NOT hard wire the power supply directly into
input voltage. Only power this turnstile from a grounding-type receptacle. Should the turnstile be
installed without a grounding-type receptacle, contact a qualified electrician to install one for you.
Waist High Installation:
New waist high turnstiles already have the 6500 series control head mounted in place.
However, should the need to replace the control head ever arise, follow these steps:
•Remove the arm assembly from the turnstile by unbolting the 3x 5/16 button head cap screws
•Remove the lid from the cabinet. Some models have a lock and key system while some others are
secured with 10/24 button head screws located on the sides.
•Unplug the control head from the grounded receptacle located inside of the cabinet.
•Unbolt the 4x 5/16 carriage bolts holding the control head assembly in place.
•Pull the control head out of the cabinet and disconnect any access control inputs from the control
board.
•Place new control head on top of cabinet and connect access control inputs to the new control
board (see wiring diagram).
•Insert control head into cabinet with the locking bars facing upwards toward you and bolt it into
place with 5/16 carriage bolts.
•Ground the power supply to the cabinet.
•Plug in the control head to the grounded outlet receptacle.
•Install arm assembly onto arm adaptor with 5/16 button head cap screws.
•Reinstall the lid.
Full Height Installation:
•Remove the cover from the mainframe by removing the 10/24 button head cap screws.
•If replacing an existing control head follow these steps first:
oUnplug the existing control head from the grounded outlet receptacle
oUnbolt the 4 3/8 carriage bolts holding the control head in place
oDisconnect access control inputs from existing control board
oPull the existing control head out
•Install the control head into the hex insert on the rotor so that the rotor aligns with one set of
arms in between the two half-moon shaped yokes
•Bolt the control head into place
•Connect access control inputs (see wiring diagram)
•Ground the power supply to the frame utilizing the provided grounding tab located
near the control head.
•Plug the control head into a grounded outlet receptacle.

6500 Series Control Head Information
All of our turnstiles and ADA gates operate with a mechanism called the 6500 series control
head. This sturdy and easy to maintain drive for the turnstile has replaced all previous model control
heads. It is adaptable to any existing turnstile and comes with each new turnstile purchase. This control
head can be configured in multiple ways to accommodate the security requirements of each individual job
site.
An internal view of an electronically controlled two-way 6500 series control head.
While the head can be configured for mechanical (no electronics) operation, the turnstile’s
security potential is reached in the case of an electronic two way control head. In this instance, each
rotational direction is independently unlocked. Configured properly, this control head will allow for one
rotation per valid entry request. Our anti-backup cams are designed so that it is impossible to become
trapped within the turnstile when properly installed.
Each control head comes pre-configured to your specific needs based off of a directional sheet
that is filled out before shipment. The heads are delivered pre-wired, tested, and adjusted to our factory
recommendations. Installation is simple: connect inputs from access control devices into the logic
controller and plug the unit’s power supply into a 110-240VAC receptacle. The power supply will
automatically set itself to function on your local voltage and convert it to 24VDC.
Note: Proper turnstile operation requires a dry, normally open momentary contact closure
(of one second or less).

6500 Series Control Head Configuration Information
The 6500 series can be configured in a number of different ways. All turnstiles operating with the 6500
series control head self center and hydraulically shock to the home position to prevent damage or injury.
Manual both ways: Turnstile rotates freely in both directions. This unsecure configuration is used as a means to
direct traffic through one area. Full height turnstiles can be purchased with a lockout bar which would allow end
user to lock the turnstile with a standard pad lock.
Manual one way: Turnstile rotates in one direction but not the other. This configuration is great for an exit way.
Electronic one way with free exit: Turnstile rotates freely in one direction and requires access credentials for the
other. This configuration is suitable for secure entry and unsecure exit.
Electronic one way with no exit: Turnstile requires access credentials for one direction and allows no passage in
the other. This configuration is suitable for a secured entryway with an alternate means of exit.
Electronic two way: Turnstile requires access credentials for both directions. This configuration is perfect for
locations requiring secured entry and exit passage.
Fail lock: Upon power failure, turnstile will remain locked in one or both directions. This is convertible to fail
open by ordering an alternate linkage. This can also be known as fail secure.
Fail open: Upon power failure, turnstile will remain unlocked in one or both directions. This is convertible to
fail lock by ordering an alternate linkage. This can also be known as fail safe.
Key override: This option is for a location that the security requirements may change. The key override option
is not intended for everyday use. Should you require an additional lockdown feature on your turnstile, a better
option is a lockout bar (Figure L) with a standard pad lock.

6500 Series Control Head Locking Bar Information
Any number of configurations is possible on the 6500 series control head. In the case of an electronic
two way head, two independent locking mechanisms are in place. The following diagram indicates which
direction unlocks from which locking mechanism. A logic controller or key override is needed to unlock the
control head in each direction it is configured to lock in.
If removing the locking bar becomes necessary for any reason, two methods can be used. The easiest
method is to punch the ½” dowel pin out from the bottom side of the control head. This releases the locking bar
from the casting. An alternate approach would be to remove the (4) ¼-20 socket head cap screws from the
casting and remove the lid.
When installing or replacing the locking bars into the control head, be sure to take special care to align
the solenoid spring (shown below) or it will not pivot properly.

Power Failure State Configuration (Fail Lock / Fail Open)
Each direction on a control head can be independently configured to open or lock upon power failure.
The fail status configuration is based on the pivot point used on the locking bar as well as the linkage and
solenoid spring used. Control heads are preconfigured in our factory before shipment based on a direction sheet
filled out by the end user. In the event a fail status field change is needed, a different linkage and spring will be
required (the part numbers are noted in a table below). Control heads can also be returned to the factory for
reconfiguration for a fee of parts plus approximately 1 hour of labor if desired.
Description Part Number
Fail lock linkage 6518
Fail open linkage 6519
Fail open solenoid spring 6510
Fail lock solenoid spring 6016
Note: As a reference, it may be important to know that some vendors use different terms
for fail status. Fail open is also known as fail safe, while fail lock is also known as fail secure.

6500 Series Control Head Shock Adjustment and Replacement
The 6500 series control head utilizes a hydraulic shock for controlling the speed of the rotation. Set
properly, the shock will allow a turnstile or gate to self-center while rotating smoothly without
slamming.
Some turnstile models use a different shock than others. Waist highs and smaller full heights use a .75”
diameter shock (Enidine brand) while the larger full heights use a 1” diameter shock (ACE Controls
brand).
Enidine brand shocks
Replacement:
Thread the new shock into the shock housing until it bottoms out and then back it out approximately 1.5
- 2 turns until the numbers near the dial are facing up. Lock down the shock with the provided nut, and
then make field adjustments to the shock strength. On some waist highs you may need to thread the
shock out an additional turn if the unit will not self-center on the lowest setting.
Setting:
Loosen the set screw on the end of the dial and turn the knob. The dial can be set between 0 and 8. The
higher the number, the stronger the shock will be. Tightening the set screw can change the strength of
the shock so a good habit is to loosen, turn, tighten then test.
ACE Controls brand shocks
Replacement:
Thread the new shock into the shock housing until it bottoms out and then back it out approximately 1.5
- 2 turns until the small set screw located near the gray dial on the end of the shock is facing up. Lock
down the shock by tightening (snugly, don’t over tighten) the set screw in the shock housing, and then
make field adjustments to the shock strength.
Setting:
Loosen the set screw at the end of the shock near the dial. The dial can be set between 0 and 8 while the
set screw itself is the pointer. The lower the number, the stronger the shock will be. Simply turn the dial
up or down to adjust the strength as desired and test.
Note: For either model, failing to back the shock out of the housing after bottoming it out can
cause it to wear out very quickly.

6500 Series Control Head Electrical Information
Each electronic control head comes with a power supply, a programmable logic controller (PLC), limit
switches (or proximity sensors) and solenoids. For safety purposes, it is recommended that you read all
literature on the electrical components before attempting to install the control head into a turnstile.
Note: Access control devices need to provide a momentary, normally open dry contact of one
second or less. A longer signal can cause more than one person to be able to pass through the turnstile. If
you are unable to provide a contact of one second or less, an onboard signal converter will automatically
change the signal length to .1 seconds. However, the ability to hold the relay open is lost while that feature
is active.

6500 Series Control Head Wiring Legend
Since each control head comes pre-wired, only access control and fire alarm should need to be connected to the
board. If you are unable to fit wires for access control on the 24VDC+ input on the board, the voltage can be
picked up directly from the power supply or from the relay commons (C3 & C4) on the board (C4 may not have
voltage depending on options purchased. There will be a red jumper to C4 if there is).
Note: Directional status outputs are unaffected by optional key overrides as the override occurs
outside of the logic controller.

Overview of the Access Window
On the logic controller, an access window is available to change and adjust many different values. Each
value is referred to as a “device”. The window comprises of 3 primary areas: The device selector window,
operation keys, and the main display window.
Although the logic controller is capable of many functions, all of the devices that the control head
operates from are accessed in “Device Mode”. When device mode is active, the display screen will show
DM in the top left corner.
That being said, it is possible to stray from the device mode settings. In the selected device type section of
the access window, DM, TM, T/C, CTC, TRM, and RLY are all possible selections to load. Again, we are
only using DM (device mode) with the 6500 series control head.
Should you find that you accidently have loaded any other selected device type, simply press to scroll
until you have once again loaded the DM type.

In addition to the device mode window, system mode can be accessed as well.
Although under normal circumstances you should never encounter this window, if by accident you should
happen to come across it, simply press the up or down arrow until the window reads “run”. Press and hold
the button for 3 seconds, and the display will return to device mode.
Additionally, should for any reason the display lettering become red instead of green, you will need to
access system mode to run the program in this fashion. Holding the key while pressing up and down
allows you to change between system mode and device mode. A third mode, which will display TRM on
the left side of the screen, can also be accessed. Cycle through until the appropriate mode is displayed.
Finally, it is possible to lock the keypad. Should you inadvertently do so, press and hold the button and
an arrow key together for 3 seconds to unlock the keypad again.

Device Settings of the 6500 Series Control Head
While working within device mode, two primary values should be considered. On the top of the display,
the selected device is shown. The 6500 series control head settings can be adjusted with devices 0 – 7.
Pressing the up or down arrows allow you to select which device you wish to modify. Pressing and
holding the key for 3 seconds loads the modification window. While modifying, the digits on the
window begin to flash. Pressing will move the cursor in a digit. Select the correct digit to modify, then
use the arrows to change the value. Once finished, hold the button for 3 seconds and your adjustment
will save.
Should an entered value not fall within the specified range of the setting being modified, the value will
automatically adjust to the highest possible value. A description of each device setting is:
•DM0: Timer value for Direction 1 - The range of this setting is 1 – 60 seconds. This is how
long the direction will remain open for if a user does not pass through the direction. The default
settingis 7 seconds.
•DM1: Timer value for Direction 2 - The range of this setting is 1 – 60 seconds. This is how
long the direction will remain open for if a user does not pass through the direction. The default
settingis 7 seconds.
•DM2: Direction 1 Power Failure Setting - This determines when the solenoid receives
power and is pre-configured based on each individual order. 0 means the direction is fail lock
& 1 means the direction is fail open. This setting is not affected by factory reset.
•
DM3: Direction 2 Power Failure Setting - This determines when the solenoid receives
power and is pre-configured based on each individual order. 0 means the direction is fail lock
& 1 means the direction is fail open. This setting is not affected by factory reset.
•DM4: Direction 1 One Shot - This setting determines whether or not the access control input
length is ignored and converted to a .1 second pulse internally. Enabling this allows the turnstile
to ignore access control from allowing too many users pass through the turnstile. Disabling it
allows access control to hold the direction open. 0 means the one-shot timer is inactive & 1 means
the one-shot timer is active.
•DM5: Direction 2 One Shot - This setting determines whether or not the access control input
length is ignored and converted to a .1 second pulse internally. Enabling this allows the turnstile
to ignore access control from allowing too many users pass through the turnstile. Disabling it
allows access control to hold the direction open. 0 means the one-shot timer is inactive & 1 means
the one-shot timer is active.
•DM6: Direction 1 Multi-swipe - This setting allows more than one access control request to
be processed at a time to allow a faster flow of traffic. The range is 1-3. As each access
controlrequest is processed, each rotation subtracts from the total, allowing a constant flow of
traffic.Most installations would benefit from a value of 2, which is the default setting.
•DM7: Direction 2 Multi-swipe - This setting allows more than one access control request to
be processed at a time to allow a faster flow of traffic. The range is 1-3. As each access
controlrequest is processed, each rotation subtracts from the total, allowing a constant flow of
traffic.Most installations would benefit from a value of 2, which is the default setting.

•DM9: Direction 1 Count - Displays how many valid rotations were made in direction 1. This
has a max value of 60,000 and will reset to 0 once that number is reached. This will not count fire
alarm, hold open or key override rotations. This count is for maintenance and repair logging
purposes.
•DM10: Direction 2 Count - Displays how many valid rotations were made in direction 2. This
has a max value of 60,000 and will reset to 0 once that number is reached. This will not count
firealarm, hold open or key override rotations. This count is for maintenance and repair logging
purposes.
Scrolling downward past DM0 will allow you access to DM1999, which resets all settings to factory
defaults (except for solenoid fail status settings). Choose any value greater than 0 to perform the
factory reset.
To view the PLC logic software version, see DM1998. A value of 120 means software revision 1.20.
Revision 1.20 introduced the revision number system as well as directional override inputs. If previous
installations desire to add this feature, the logic controller can be shipped back to Controlled Access,
Inc. for a software upgrade or a replacement controller can be purchased.

Direction 1 is canceled by limit switch 1 and direction 2 is canceled by limit switch 2. As the unit
rotates, both limit switches are triggered. However, only the limit switch designated for that direction is
utilized to relock the unit. The switch is triggered towards the end of the rotation. Once it is triggered, the
locking mechanism returns to the locked position, but users may still proceed until the home position is
reached.
A minor exception to this is in the case of an ADA swing gate. The limit switch is triggered
towards the beginning of the swing, which allows the locking bar to prevent the gate from over swinging.
In this instance, the limit switches are designated backwards from those on a standard turnstile. Refer to
the above diagram to illustrate which is which.
Note: The control head will not operate properly if the limit switches and top cam are not
adjusted properly or altered from factory shipment.
