Product description
Tripod Turnstile is a complete, compact access control
point. It combines motorized rotating barrier with
RFID readers to control entrance and exit. Because
everything is integrated into a single housing, it
reduces required space for passage.
For exit control a patented Metra Wristband Capturer
can be integrated to allow Ticket retain feature. The
storage drawer for captured wristbands and/or cards
is incorporated in the housing that is a combination of
stainless steel body in matte finish and synthetic or
carbon fibre reinforced resin cover. Fluent pedestrian
passage is achieved by combination of visual LED and
audio signalization and proximity sensors triggering
motor driven rotating barrier. The drive was designed
and proven to prevent any injury but is tough enough
to withstand misuse at the same time. The barriers
are free rotating if the mains power is down and can
also be equipped with a special breaking fuse
(mechanical) for the case of panic.

Page 4
Tripod Turnstile Technical Manual
Tripod Turnstile is connected to Metra NET Network. When RFID Ticket is presented, access rights
are checked in the Metra software check engines. If valid, the unit drives its rotating barrier in
desired direction.
Passage on Tripod Turnstile for a particular ticket can also be externally controlled by 3rd party SW via
TCP/IP software interface. Metra software is used for event analyses and definition of operating
parameters.
Ticket retain feature allows re-using of various tickets. For that
innovative feature Metra has developed patented in 1998 contact-
less Wristband Capturer (WBC) together with contactless RFID
Wristband. The Wristband Capturer grants exit signal only when the
ticket is successfully erased and retained. This dramatically cuts
costs of the system operation and the chance of fraud. A ticket will
be retained under following conditions:
Retain request written on it/assigned to it.
It is presented to the retaining device.
Basic parts
Wristband Capturer (optional)
Wristband Capturer is a retaining module for Metra RFID
wristbands. It is integrated in different Metra products such
as Tripod Turnstile and Turnstile Access Terminal.
Consult the “Wristband Capturer – Technical Manual” for
more details.

Mounting set (optional)
Beforehand provided anchors (if the anchors are going
to be built-in the pave)
2 x built-in anchors (left and right)
2 x spacers for anchors
6 x M8 nuts
Choosing location for installation
Placement of device is chosen regarding the project plan. Take into consideration the following
advices regarding the orientation and location of Tripod Turnstile(s):
Receptionist should have good overview to the front side of the device(s).
The best position regarding reception desk is that receptionist has access to incoming and leaving
guests (extra payment on leaving).
When an entrance for disabled persons is mounted, it needs to be at least 90 centimetres wide.
If the device stands alone, you need to mount a barrier at 50 to 55 centimetres from edges or find
already fixed barrier (wall, column, etc.). The barrier should be of the same high as the device,
which is 1 metre.

Page 7
Tripod Turnstile Technical Manual
If there is more than one device in a row, only the first Turnstile needs a fixed barrier. Other
devices are using next device as a barrier.
On the left and right side of the device there need to be at least 30 cm of free space to take out
the storage with captured tickets.
Devices should also be protected from direct sun and rain. The best place for this purpose is inside
the building or under projecting roof.
At night or when device is out of (stuff) control, it is better to have some kind of protection
against vandalism (wire fence, door, etc.).
When the device is installed directly on concrete foundation, durable carpet should be provided.
Fixing the Turnstile is done in two levels which also enable micro settings and out of season de-
montage.
When you do concrete, we advise to do larger surface (plate) for better solidity of installation.

Wires installation
NOTE 
Before the installation of the device the built-in anchors and wire installations must be checked.
Anchor position (orientation)
Check the position of both built-in anchors and their height and position according to the pavement.
Clean the surface of the built-in anchors.
Preparation of wiring
Put a ribbed plastic hose 30 millimetres for installation
of cables through the anchor on the entrance side. If
installation requires (for example: external Enter/Exit
buttons are on different location than Power supply and
Metra Net Network), more than one ribbed plastic hose
can be put in. Each installed cable should be at least 1.5
metre long from the ground.
Wiring
NOTE 
Cables are always installed through the leg on the ENTRANCE SIDE of the Tripod Turnstile.

Anchor installation
See chapter “Mounting set (optional)“ for required mounting elements.
STEP 1: Fix iron anchor spacers to the anchors with
supplied M8 nuts.
STEP 2: “Cut” sides of the anchor's (top view) should be
placed at the Turnstile's passage side.

Page 10
Tripod Turnstile Technical Manual
STEP 3: Anchors are put onto the place where the tripod
barrier device will stand. Be sure that anchors are
balanced in both horizontal directions. The concrete is
applied according to the final foundation (pave).
NOTE 
Setting the 0/0 position: It is demanded that the anchor
spacers are placed onto the final foundation of the
existing level - the upper surface of both anchors is on
the same level as ceramics, marble, final foundation, etc.
When the concrete is dry, the anchor spacers are
removed and can be used again.
STEP 4: Attach the Tripod Turnstile on the anchors and
fix it with 6 x M8 nuts. Use M8 washers with external
diameter at least 24 millimetres or bigger. Washers are
not included with the anchors and must be bought
separately or they are provided by Metra when installing
the Tripod Turnstile. There are also rubber pads available
if anchors are slightly out of level and they are also used
for water insulation if needed. Contact Metra for more
details.
STEP 5: Final position of devices should look like these.

Page 11
Tripod Turnstile Technical Manual
Other installation options
Alternative mounting options are also possible.
If installing Tripod Turnstile indoors into a solid
pavement, it can be mounted using wall plugs, anchor
bolts, anchor screws, and even special glues. However,
the underground wiring needs to be done before the
installation of Tripod Turnstile. Method should be chosen
depending on the pave type.
NOTE 
Drilling holes in pavement is not advised in the following cases:
Non-solid pavement.
Floor heating.
Other floor installations.
NOTE 
Wiring scheme remains the same for all kinds of installations.
Opening cover
STEP 1: Unlock and remove the ticket container on one
side and the door on the other side of the Tripod
Turnstile.
STEP 2: There is a buckle holding the Cover in place on
each side. Unbuckle them.
STEP 3: Lift the Cover. If needed disconnect the
signalization panel, Reader (if present) and Wristband
Capturer (if present). Mark cables exact position.

Power supply connection
Regulated 24 VDC power supply is required for proper operation. Consult the Technical Specifications
section of this document for current consumption.
Connect 24V DC regulated power supply to designated
terminals. The terminals are marked as “+24”for positive
connection and “gnd”for ground connection.
WARNING 
Mind the polarity! Wrong polarity could result in
irreparable damage to the device.
Respect power requirements data! Using unsuitable
power supply could result in damage to the power
supply and to the device.

Page 15
Tripod Turnstile Technical Manual
NOTE 
Make sure that Power/Network cable is connected to the distribution board.
Network connection
The network connection provides for operational functionality of the Tripod Turnstile. Different
devices in parallel can be connected to the Network Controller by a single unshielded twisted pair
(UTP) cable. Total length of the twisted pair cable is limited to 1 km. One Network Line Terminator
must be connected at the far end of the network cable.
OPTION I:
Connect the twisted pair network cable to designated
terminals. The terminals are marked as “C_L”for network
low signal and “C_H”for network high signal.
OPTION II:
Connect the twisted pair network cable with RJ-45
connector to one of RJ-45 connectors on the “connection
board”.
NOTE FOR OPTION II 
There are 2 equivalent UTP connectors for Metra NET Network connection. One can be used as
“trunk line IN” and the other as “trunk line OUT”connector. Take into consideration that if you
disconnect one of the UTP cables (in or out), you also cut off the “trunk line” and devices after this
device will be disconnected from the Metra NET Network. Therefore this type of connection is
recommended only if you use Master and Slave Network Controllers TCP/IP, each on one side of the
“trunk line”.
NOTE 
Mind the polarity of the network connection!
Always connect the line terminator at the far end of the network cable!

Safety features
Different safety features are available on the Tripod Turnstile
Free passage
If mains power is down the barrier is rotating freely in both directions.
Special braking fuses (optional)
If even higher safety is required, barriers can be equipped with special braking fuses that brake if
high force is applied to the barriers (people leaning on the barrier, mass of peoples push against the
barrier). Barrier can be easily and quickly reinstalled using a new braking fuse.
Barrier calibration
Each barrier (when in top position) should be
perpendicular to the metal housing. Consult “Turnstile
Drive Mechanism II –Technical Manual” for barrier
calibration procedure.

Page 20
Tripod Turnstile Technical Manual
Maintenance
The maintenance service should perform a check on the device:
At least once a year.
When it has not been in use for a long time.
When functional errors appear.
The device should be protected from mechanical damages, such as bending barriers and similar,
which usually result from improper use like jumping over the barrier or climbing over the bars. Such
abuse can be detected by proximity sensors and will be signalized by a beep sound, if enabled in
device parameters.
Cleaning
The device housing should be cleaned using only detergents, suitable for rust resistant metals. The
resin cover should be cleaned using soft cloth and dedicated cleaners for plastic surfaces e.g. car
dashboard cleaning agents. Do not use any aggressive or abrasive agents or solvents as they might
cause permanent damage to the device surface.
