TTR-04CW Electromechanical Tripod Turnstile
5 PRODUCT DESCRIPTION
5.1 Main features

The turnstile can be operated from the RC panel or WRC kit as well as from an
ACS.

The turnstile is designed either for indoor application or outdoor under shelter (see
Clause 2) and is equipped with a heating system with thermocontrol.

The turnstile retains the set position for each direction when the power is switched
off — the open passage direction remains open, the locked passage direction
remains locked.

The mechanical release lock built into the turnstile housing ensures the turnstile
unlocking with a key in emergency cases (free rotation of barrier arms).

The turnstile has relay outputs for connection of an intrusion detector and a siren.

The turnstile has outputs for connection of remote indicators.

A purpose-designed “Fire alarm” control input is intended for unlocking the turnstile
at the fire alarm command or from emergency unblocking button.

There are two modes for the turnstile control — a pulse control mode and a
potential control mode.

After each passage the turnstile provides automatic complete rotation of the barrier
arms to home position, i.e. automatic reset.

Smoothness of reset and quiet operation are ensured by a damper.

The optical arm rotation sensors are built into the turnstile housing to ensure
accurate count of inputs to an ACS.

The turnstile is supplied with safe voltage — maximum 14 V, with the heating
system with thermocontrol in operation — no more than 40 V.

The turnstile has low power consumption — maximum 8.5 W, with the heating
system with thermocontrol in operation – maximum 70 W total.

Galvanic decoupling of the outputs ensures noise-immunity of the turnstile
electronics.
5.2 Design
The design of the turnstile is shown in Fig. 2. Numbers in brackets correspond to Fig. 2 of
this Manual.
5.2.1 The turnstile housing (1) is a welded metal structure with a cover (2). In an upper
part of the turnstile housing there is a rotation mechanism (4) with three barrier arms (5), a
locking device, a self-centering mechanism and arm rotation sensors. A LED indication
display is located on the front panel of the cover (2). The turnstile
housing is equipped with
the heating system with thermocontrol.
5.2.2 The large LED indication display with bright pictograms is intended for status and
direction indication: a Green Arrow indicates the direction of an authorised passage (the
turnstile is open in the set direction); a Red Cross indicates ban on passage (the turnstile
is locked).
In the left-hand bottom corner of the LED indication display of the turnstile housing there is
an additional LED indicating operating modes of the built-in heating system with
thermocontrol. The LED is green when the heating system with thermocontrol is powered
up, and it is amber when the heater is in operation).
