Installation Instructions
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 buffered. 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.
Counterclockwise
Rotation
Turnstile arms rotate in a counterclockwise 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 section (roto) cannot be rotated in the fail-lock
direction(s).
Fail-Safe
Relevant to electric models only.
Upon loss of power, the 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 by an activation. Alternatively,
key override control allows each direction of rotation to be unlocked, 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 MST and MSTX as the basis of
instruction. Most steps are identical across models. Differences in components or installation process are called out, as
applicable. These instructions are applicable for the installation of the following models:
MST-3 CLST-3
CPST-6X FMST-3
MST47-3
MST-6X
CLST-6X FMST-6X MST47-6X
