Common Terms
Activation Activation (unlocking) of electric models is accomplished by providing a momentary
dry contact of .5 seconds to 2 seconds or greater to the appropriate location on the
turnstile control board. Activations are not bu󰀨ered. After an activation is received, the
turnstile will not accept another activation until the turnstile is rotated or the activation
has timed out (see Time-Out below).
Clockwise Rotation Turnstile arms rotate in a clockwise direction.
Counter-Clockwise
Rotation
Turnstile arms rotate in a counter-clockwise direction.
Electric Lock
Control
Relevant to electric models only.
Electric units (“6X” models) provide electric lock control. The turnstile is unlocked
by providing an activation (unlock signal), in the form of a momentary dry contact of
.5 seconds to 2 seconds, to the appropriate location on the turnstile control board.
Separate controls are provided for each direction of rotation.
Fail-Lock Relevant to electric models only.
Upon loss of power, the rotating Roto's cannot be rotated in the fail-lock direction(s).
Fail-Safe Relevant to electric models only.
Upon loss of power, the rotating section Roto freely rotates in the fail-safe direction(s).
Key Override All full height turnstiles, whether manual or electric, come with key locks, located on
the underside of the Top Channel, to allow key override control of the Roto. Separate
key overrides are provided for each rotation direction.
For manual units (“3” models), the key override control allows each rotation direction
to be either locked (no passage) or unlocked (free passage).
For electric units ("6X” models), key override control allows each rotation direction
to be locked, in which case the turnstile can be unlocked in normal operation.
Alternatively, key override control allows each direction of rotation to be unlocked
in override operation, in which case the turnstile will freely rotate in the unlocked
direction(s).
Manual Control Manual control of the turnstile is available through use of the key override control
function (see above).
Self-Centering The turnstile arms automatically return to home position once rotation has been
completed.
Time-Out When the turnstile receives an activation (unlock signal), the user is allowed a set
time to pass through the turnstile before it automatically re-locks. The factory default
time-out setting is 20 seconds. The turnstile control board allows the user to decrease
this time setting to 5, 10 or 15 seconds.
Before You Begin
This manual focuses on the installation of Alvarado full height turnstiles, using the MSTT and MSTT-X as the basis of
instruction. Most steps are identical across models. Di󰀨erences in components or installation process are called out, as
applicable. These instructions are applicable for the installation of the following models:
MSTT-3 CLSTT-3 CPSTT-6X FMSTT-3
MSTT-6X CLSTT-6X FMSTT-6X

Installation Instructions
NOTE
Install the turnstile on a 8' x 6' level concrete slab. The
slab must be a minimum of 4" thickness. The turnstile may
only be installed on concrete. Do not install the turnstile on
asphalt.
NOTE
DIMENSIONS SHOWN ARE FOR MSTT MODELS. SEE
APPENDIX A AND B FOR OTHER MODELS.
Installation Locations
1. Determine where the turnstile will be installed. Consider the overall footprint size of the unit when determining
the installation location (Figure 1). Once the installation location has been determined, use a chalk line to mark
the centerline of the turnstile.
2. Determine and mark the centerline location for the OV, Rotos and Yokes (Figure 1).
NOTE
The overall height of the MSTT is 91.5". However, an additional 3" of clearance must be added for service and
maintenance.
Mark all center lines prior to installation.

Bottom Bearing Plate Installation
Fig. 2
1. Place the bottom bearing plate over the turnstile
and Roto intersecting lines.
2. Mark the center location of all four anchor holes for
the bottom bearing plate (Figure 2). Set aside the
bottom bearing plate.
3. Using a ⅝" concrete drill bit, drill four anchor holes,
3" in depth, at the center of each marked location
(Figure 2).
NOTE
The anchor hole(s) must be clean before installing
the anchor bolt(s). If the hole(s) are not clear of
debris, the anchor bolt(s) may not tighten correctly.
4. Insert one anchor into each drilled hole (Figure 3).
The threaded end of the anchor must be inserted
into the hole rst. Use a hammer to tap the anchor
into place, if needed. Ensure that the anchors are
ush with the concrete oor.
5. Place the bottom bearing plate back over the
anchor holes and anchor it with four (4) ⅜" x 2½"
anchor bolts and at washers (Figure 4).
6. Use a socket wrench and 9/16" socket to tighten
the anchor bolts (Figure 5).
7. Conrm that the bottom bearing plate is level. Shim
as needed.
8. Apply a thick bead of clear RTV silicone around the
bottom bearing plate (Figure 5).
9. Repeat Steps 1 through 8 for the second bottom
bearing plate.
NOTE
Clear RTV silicone is a low volatile formula and can
be used in a variety of applications.

Yoke Installation
NOTES
Do not use a single Yoke as a template when multiple turnstiles are
installed, as Yoke dimensions may vary slightly from Yoke to Yoke.
NOTE DIMENSIONS SHOWN ARE FOR MSTT
MODELS. SEE APPENDIX A AND B FOR
OTHER MODELS.
1. Reconrm the centerline location for the Yoke (Figure 6).
2. Using a ⅝" concrete drill bit, drill an anchor hole 3" in depth.
NOTE
The anchor hole(s) must be clean before installing the anchor
bolt(s). If the hole(s) are not clear of debris, the anchor bolt(s)
may not tighten correctly.
3. Insert one anchor into the drilled hole (Figure 7A). The
threaded end of the anchor must be inserted into the hole
rst. Use a hammer to tap the anchor into place, if needed.
Ensure that the anchor is ush with the concrete oor.
4. Place the Yoke back over the anchor hole and anchor it with
one ⅜" x 4½" anchor bolt and at washer .
NOTE
Prior to drilling the remaining anchor holes, use a tape
measure and measure the distance from the bottom bearing
plate center to the remaining mounting holes on the Yoke
(Figure 6). Adjust the Yoke until these two distances are
identical. Mark these two locations.
5. Rotate the Yoke to the left. Using a ⅝" concrete drill bit, drill
two anchor holes 3" in depth at the center of each marked
location.
6. Insert two anchors into the drilled holes (Figure 7A). The
threaded end of the anchors must be inserted into the holes
rst. Use a hammer to tap the anchors into place, if needed.
Ensure that the anchors are ush with the concrete oor.
7. Rotate the Yoke back over the anchor holes and anchor it
with two ⅜" x 4½" anchor bolt and at washer (Figure 8).
8. Once the Yoke has been anchored, use a socket wrench
and 9/16" socket to tighten the anchor bolts (Figure 9).
9. Conrm the Yoke is level and plumb. Shim as needed.
10 Repeat Steps 1 through 9 for the second Yoke.

NOTE
Prior to installing, liberally apply a coating of grease to the shaft, top of the bearing, sides of the bottom
bearing plate and inside the bottom bearing plate (layer ¼" to ½" in thickness). Applying grease as
indicated will help protect against moisture and foreign matter penetrating the bearing area.
1. Attach the bottom bearing, collar facing up, to the
lower end of the Roto (Figure 11) by sliding the
bottom bearing onto the mounting shaft
(Figure 11A).
