2.2 Ex Product Interface
The interface of the Ex Products consist of the elements in the following chapters.
2.2.1 Status LEDs
Present on all Ex Products.
Green Power LED
The Power LED is lit to indicate that the access panel is powered up.
The Power LED flashes to indicate that the device has no connection to the central equipment.
Yellow Fault LED
The Fault LED is lit to indicate that there are faults in the system.
The Fault LED flashes to indicate that the device is connected to (link OK), but not registered with
the central equipment.
Red Call LED
The Call LED is lit when an intercom is in a conversation, or the microphone on an access panel is
active.
2.2.2 Function Buttons
Present on all Ex Products.
These are fully programmable buttons which appear in different forms on different units.
Right-aligned Function Buttons have two programmable LEDs (green and red) to indicate status
information related to the function.
For right-aligned Function Buttons, button protection covers can be attached to avoid a button
being inadvertently pressed.
2.2.3 Numeric Keypad
Present on TFIX-1, TFIX-3 and TFIX-4.
These have a predetermined function.
Dialing buttons 0 - 9, present on TFIX-1 and TFIX-4, are used for calling specific numbers or
triggering functions.
M-button, present on TFIX-1, TFIX-3 and TFIX-4, is used for answering calls, Push-To-Talk and
changing from external to internal audio devices.
C-button, present on TFIX-1, TFIX-3 and TFIX-4, is used to cancel a current action or state.

3 System design overview
3.1 Connection to central equipment
The Ex Products are connected to the central equipment rack using Ex certified 2-wire cable with
shield. A Zenitel proprietary protocol, Flowire, is used to extend the Ethernet connection and
support power distribution on the 2-wire cabling infrastructure.
To support the Flowire interface, the central equipment rack must be equipped with a Flowire
Converter (FCDC2).

3.5 Ex Protection Strategy
The Ex panel shall comply with the following standards:
IEC 60079-0: Explosive atmospheres - Equipment - General requirements
IEC 60079-7: Explosive atmospheres - Equipment protection by increased safety "e"
IEC 60079-11: Explosive atmospheres - Equipment protection by intrinsic safety "i"
IEC 60079-18: Explosive atmospheres - Equipment protection by encapsulation "m"
3.5.1 Increased safety “e”
The mechanical enclosure complies with requirements for increased safety (Ex "e").
The Ex "e" part of the main board includes the Flowire screw terminals.
3.5.2 Encapsulation “m”
Encapsulating the entire board ensures compliance with requirements for protection by
encapsulation (Ex “m”). Encapsulation removes the risk of sparks and provides thermal
protection to ensure that the surface temperature of the potting compound is below T4 limit
(135 °C).
The level of protection is "b" to comply with zone 1 equipment.
3.5.3 Intrinsic safety “i”
The following parts comply with requirements for intrinsic safety (Ex “i”):
A100C08127 - Turbine Front Board Extended
EMMAX-1H - Exigo Handheld Industrial Ex Microphone, 1 Button
AK5850HS Ex-Approved Headset with plug
TAX-2 - Turbine Ex Approved Headset, Pluggable
TAX-2B - Turbine Ex Approved Cable for Headset with PTT
TAX-3 - Turbine Ex Approved Handset with PTT, Unterminated
The barrier design on the main board provides “b” level protection (Ex ib) to the intrinsically
safe parts, supporting zone 1 requirements.
Um: 250V

Doc. no. A100K11499 Page 17
3.5.4 Marking
Based on the requirements of zone 1, T4 and the chosen concept of protection, the Ex Product
shall include the following marking:
II 2(2)G Ex e ib mb (ib)IIC T4 Gb
If the sign “X” is placed after the certificate number, it indicates that the equipment is subject to
special condition for safe use.
Special condition for safe use:
The cable glands shipped with this product has an impact resistance of max 4J.
Due to low impact resistance of the cable glands, the units shall only be installed in areas where
there is a low risk of impact.
If cable glands supporting high impact (7J) are used, the X condition does not apply.

4 Installation
4.1 General
Improper installation and operation of the Ex access panel will result in the invalidation
of the guarantee.
The enclosure/housing must not be opened when the product is powered.
The installation and connection of Ex units may only be carried out by qualified
approved personnel.
The maximum voltage (Um) that can be applied to the non-intrinsically safe connection
facilities of associated apparatus without invalidating the type of protection is 250V
Special condition for safe use
The “X” after the certificate number indicates that the equipment is subject to special condition for
safe use.
The cable glands shipped with this product has an impact resistance of max 4J.
Due to low impact resistance of the cable glands, the units shall only be installed in areas where
there is a low risk of impact.
If cable glands supporting high impact (7J) are used, the X condition does not apply.
4.2 Mounting
When the Ex Product is mounted directly onto a wall or mounting plate, it shall rest only on the
fastening points provided for this purpose. The surface must be even and flat.
The unit must be mounted on the surface to prevent access from the back.
To mount the panel:
1. Open the enclosure by loosening the 12 screws that secure the front frame to the on-wall
box.
2. Open the enclosure by pulling the front frame out 5 mm, keeping it parallel to the on-wall
box. This is necessary to get clearing for the hinges. Then pull the right side of the front
frame to fully open the enclosure. Make sure to not open the enclosure so far that cables
between the front and back parts are pulled tight.
3. Fix the station to the wall, mounting plate or column with four screws that fit the four screw
holes in each corner of the on-wall box (6.7 mm diameter). (Ref. drawing on page 22)
On Mounting plate or column
M5 x 20 or 25 with Philips head DIN7985 or Torx.
Head diameter 10mm.
On Wall
Panhead –DIN7981 for plug or wooden wall, etc.
Head diameter 10.8 B5.5 x 38 or 45 mm

Ex Turbine Intercoms & Exigo Access Panels
Page 20 Doc. no. A100K11499
Do not use countersunk screws.
Due to the cabinet material, use as low a tightening torque as possible
Washers are recommended
4. Carry out Electrical connections (chapter 4.3)
5. Move the front part back to its original position and fasten the 12 screws.
Do not use more than 2.5Nm torque when fastening the 12 screws in the front frame.
4.2.1 Opening the enclosure
1Open the enclosure
by loosening the 2
screws that secure the
front frame to the on-
wall box
2Open the enclosure
by pulling the front
frame out 5 mm,
keeping it parallel to
the on-wall box. This is
necessary to get
clearing for the hinges
3 Then pull the right side of
the front frame to fully open
the enclosure. Make sure to
not open the enclosure so far
that cables between the front
and back parts are pulled
tight.
