IMPORTANT SAFETY WARNINGS
WARNING: Always follow installation and operating precautions, including the
following:
•Read this manual in its entirety before installing or operating the turnstile. If there are
questions, you may contact Alvarado at [phone] (US) during normal business
hours.
•Use only skilled individuals to install and service the turnstile.
•The turnstile is not a toy. Do not allow children to play on or near the turnstile. Do not
allow horseplay near the turnstile.
•Follow a proper maintenance schedule using skilled individuals.
•Do not operate the turnstile if it is damaged in any manner. Have the turnstile
repaired or adjusted by a skilled service person before use.
•Do not alter the turnstile.
•For electrically controlled units, which do not have self-centering, do not remove or
disable lock arms. If controlled access is desired in only one direction, install a
pushbutton (available from Alvarado) to control access in the opposite direction.
•For electrically controlled units, which do not have self-centering, do not use
mechanical key overrides to allow uncontrolled passage unless the access control
system or turnstile is malfunctioning. Mechanical key overrides are intended for
limited use in special situations under the direction of operating management (i.e.
gate attendant). Have the access control system or turnstile repaired immediately.
•Do not operate the turnstile unless the friction brake is operating and adjusted
correctly.
•If a self-centering option is utilized, do not operate the turnstile unless the self-
centering unit is operating and adjusted correctly.
•Do not use non-Alvarado parts when repairing the turnstile.
•In access control application, train personnel that will be using the turnstile in the
proper method of operation. Ensure that as new users are added, they are properly
trained. (See Turnstile Operation/User Instructions Section)

PAD REQUIREMENTS
6’ x 6’ LEVEL CONCRETE PAD - MINIMUM THICKNESS 4”
DO NOT INSTALL INTO ASPHALT
LAYOUT
1. Determine where to install the turnstile.
Note the minimum width and height
openings on detailed drawings. Draw a
6 ft. chalk line to mark the centerline of
the turnstile. See Fig. 1.
2. Using the turnstile anchoring view
drawing on page 27, mark the exact
locations (along the turnstile centerline)
of the roto center, the center yoke hole,
and the OV centerline. See also Fig. 2.

INSTALLATION continued
3. Locate and chalk mark the four
anchor holes for the roto
bearing housing, using the
bearing housing as a template.
(See Fig. 3) Drill the four 5/8”
dia. holes for the roto bearing
housing. All holes should be
drilled a minimum of 3” deep.
Terrazzo, brick veneer, thick
tile, see page 26 for additional
instructions.
INSTALLATION OF ROTO
BOTTOM BEARING HOUSING
4. Clean the holes and
insert one anchor in
each hole flush with
the floor. (See Fig. 4)
NOTE: Insert anchors
with threads down.
5. Place the bearing
housing over its
respective anchor
holes and anchor it
using four (4) 3/8” x 2
½” bolts and flat
washers. Make sure
that the housing is
level. Shim as needed.
(See Fig 5).

INSTALLATION continued
6. Drill a 5/8” hole 3” deep marked
at the yoke center chalk line.
Clean hole and install anchor.
Install the yoke center bolt
using a 3/8-16 x 4½” HHCS and
washer through the hole of the
yoke over the center anchor
hole and hand tighten. (Fig. 6)
Pivot the yoke and measure the
distance from the center of the
bottom bearing housing to the
center of each of the other two
yoke holes, making sure the
distance is the same to each.
This “sparing of the yoke” is
necessary so that the entrance
and exit are equal in distance.
(See Fig 7)
INSTALLATION OF YOKE
7. Mark the yoke mounting holes.
Drill and clean and insert one
anchor into each hole. Pivot the
yoke with the center bolt
installed to clean, drill and
install anchors. Anchor the
yoke. Mount using three (3) 3/8-
16 x 2½” HHCS and three (3)
3/8” flat washers.
8. Using a torpedo level ensure
that the yoke is vertical. Shim
as needed.

INSTALLATION continued
9. Slide the OV section into position.
(See Fig. 8) (the position should have
been marked when the first chalk
lines were made.) Mark the location
of the four anchoring holes for the
OV. Remove the OV and drill the four
marked holes (5/8” holes, 3” deep).
Insert one anchor in each hole,
tapping anchor flush with the ground
so it is level. Then reposition OV over
its anchoring locations. Anchor the
OV using four (4) 3/8-16 x 2½” HHCS
and washers. Check for level and
plumb using a torpedo level.
INSTALLATION OF OV
INSTALLATION OF ROTO SECTION
10. Locate the roto section, bottom
bearing and base cover. Slide the
base cover over the bearing housing.
(See Fig. 12, pg. 9) Fit the bottom
bearing into the roto shaft. Note: the
flange portion of the bearing fits “up”
into the roto.

INSTALLATION continued
11. Apply a light coating of grease to the
shaft mounted on the channel and
the interior spline of the roto to assist
in the sliding together of these
pieces. (See Figs. 10 & 11)
12. Grease interior portion of the
bearing housing and place
bearing housing cover over
housing. (See Fig. 12)
13. Place the roto section into the
bearing housing. Make sure the
bearings turn freely and there is
no binding.

INSTALLATION continued
14. With a person holding the
roto section upright, lower
the top channel on top of
the yoke and the roto. (See
Fig. 13 & note below)
INSTALLATION OF
TOP CHANNEL
NOTE: The shaft is missing a valley in the splines. Align this area with the additional
ridges in the roto portions. The correct placement will have the roto unit with one set of
arms directly in the middle part of the yoke section. The fit is often very tight. Use a
mallet to seat the top channel and shaft while moving the roto.
PLEASE NOTE: Hit the shaft only on the center section of the shaft. Hitting the
brake unit or the self-centering unit will only damage these parts and will not aid
in installation.

INSTALLATION continued
15. Attach the top channel to the
yoke using two (2) ½ -13 x 1½”
bolts, washers and nuts. (See
white arrows in Fig. 14) Do not
tighten at this point.
Note: If turnstile has a card
reader, run wires through the
yoke with pre-installed feeder
wire. Feed wires through to
the inside of top channel. Use
outer holes in top channel for
wire placement. (See circled
area in Fig. 14)
16. Attach the top channel to the
OV section using two (2) ½ -13
x 1½” HHCS, nuts and
washers.
17. Slide the yoke guard plate
slotted end first, between the
top channel and the yoke.
Ensure that the feeder wire is
not being pinched between the
top channel and the yoke and
yoke plate. Secure using one
(1) ½ -13 x 1” HHCS, nut and
lockwasher. (See black arrow in
Fig 14)
18. Tighten all anchoring bolts to 20 ft-lbs. (11 total) to
check the plumb of the turnstile. Shim as necessary,
then tighten bolts securely.
19. Mark locations for six holes on the yoke guard plate.
Drill a .1495” dia. (#25 drill bit) hole in the locations
marked. Drill the pilot hole through both the yoke
guard plate and the top of the upper yoke arm.
Attach the yoke guard plate to the yoke arm with six
(6) #10 x ¾” pan head slotted sheet metal screws.
20. Attach top bearing cover with five (5) 10-32 x ½”
allen head screws.
21. Check friction break mechanism by holding the lock
arm open and rotating the turnstile. There should be
a small amount of drag (3 to 6 lbs). If adjustment is
necessary, follow the instructions on page 31.
NOTE: Friction brake is not present on self-centering
units. See page 37 for self-centering adjustment
information
22. For electrical connections, refer to wiring diagrams
listed on pages 12 through 25.
23. Reattach the top channel cover
24. Recheck the brake tension approximately two
weeks after installation and re-adjust if necessary.

ELECTRICAL AND ACTIVATION WIRING INSTRUCTIONS
TOOLS REQUIRED: Wire Stripper
PARTS REQUIRED: Wire Nuts
INSTRUCTIONS
(NOTE: USE ONLY SKILLED ELECTRICIANS TO CONNECT POWER)
1. Make sure that primary power to the unit is off.
2. Locate the drawing showing the appropriate turnstile version.
(I.e. 5X failsafe, 5X fail lock)
3. Remove top channel cover.
4. Make electrical and necessary activation connections per the appropriate drawing and
local electrical standards.
5. Review all electrical wiring and contacts for exposure to any metal parts that may lead
to a short.
6. Manually rotate the turnstile and inspect microswitch contacts to ensure that switch
arm is depressed but not distorted.
7. Attach cover.
8. Turn on primary power and test operation in each direction completely. If faillock verify
that upon loss of power turnstile remains locked. If failsafe, verify that upon loss of
power turnstile remains unlocked.

TURNSTILE CONFIGURATIONS
OTHER OPTIONS
Non-Electric
MST-1
Turnstile is free rotating in one direction.
Locked in opposite direction.
MST-2
Free rotating in both directions.
MST-3
Three-position key lock control allows
turnstile to remain locked in both directions,
unlocked in either direction or unlocked in
both directions.
Electric
MST-4X
Electrically controlled in one direction.
Locked in opposite direction.
MST-5X
Electrically controlled in one direction. Free
rotating in the opposite direction. (Sold only
with self-centering option) Do not use this
configuration without a properly operating
self-centering feature.
MST-6X
Electrically controlled in both directions.
Fail Lock
Turnstile locks when power is removed (or
lost). Turnstile will unlock when power is
supplied. This is how the turnstile leaves the
factory unless specified otherwise.
Fail Safe
Turnstile unlocks in the event of power loss,
which permits free passage through the unit.
Power must be supplied to the unit for re-
locking.
Timed Delay Relay (TDR)
In a turnstile without this option, if a patron
does not pass through after activation, the unit
will remain unlocked indefinitely. This option
provides the capability to make the unlocked
time finite through the use of a field adjustable
(0.3 to 30 sec.) time delay relay. Once
activated, the unit unlocks and the timed cycle
begins. If the turnstile is not operated before
the end of this delay cycle it will relock,
requiring another activation to allow passage.
Self-Centering
Provides for correction of under or over
traveling of the turnstile arms following
completion of a passage cycle. One of the three
center section arms will center in parallel with
the top channel.
Key Override
Allows one or both directions of passage to be
mechanically unlocked with a key. Locks are
located on the underside of channel near the
bearing housing. When both directions are
specified to have key overrides, locks are
keyed alike. Note: For electrically controlled
units, mechanical key overrides are intended
for temporary use when the turnstile or access
control system has malfunctioned and under
the direction of operating management. Have
the access control system or turnstile repaired
immediately.
Interface Relay (IFR)
The momentary dry contact (less than 0.5
sec.) required to activate the turnstile cannot
be provided by some access control systems.
The purpose of the momentary pulse relay is
to convert the maintained signal provided by
the access system to a momentary signal,
which can be used to activate the turnstile
