5 or 10 lines while the ETB-100/ETB-100A is a Command Talk-Back &
Public Address system with 10 lines. The ETB-100A can also be used as
an emergency Public Address system. The system comprises a central
unit and a comprehensive range of substations and other eld equipment
for use indoors, outdoors, and in noisy areas on marine vessels. The
physical dimensions of the units are based on the Euro DIN standard
and t neatly into integrated bridge solutions.

1.5.8 Extra Signal in the ETB Central Unit
An extra signal device can be activated when receiving
calls from a substation through a potential-free contact in
the central unit.
1.5.9 Handsfree Operation
Handsfree operation of central unit or parallel station.
Option 1
Central unit with gooseneck microphone MB-30G and foot
switch U2410.
Option 2
Parallel station type STB-6GN with gooseneck microphone MB-30G and
foot switch U2410.
1.5.10 Privacy Function - STB-1
Substation STB-1 is designed for indoor use such as cabins, mess
rooms, etc. It is also equipped with a privacy function.
When the privacy function is enabled, it is not possible to hear
communication from the STB-1 substation on the ETB central unit.
After a call is set up from the central unit, the operator of the STB-1
substation has to press the TALK button to communicate with the central
unit.
STB-1 can also be set to normal talk-back function.
1.5.11 Panel Loudspeaker
The loudspeaker is located at the front panel of the ETB-100 and ETB-
100A central unit for distribution of audio messages and alarm signals.

1.5.12 External Loudspeaker (Option)
The optional external loudspeaker with 40W impedance is for improved
and higher audio volume level.
The loudspeaker is connected in parallel with the monitor speaker and
located close to the ETB central unit.
1.5.13 Line Button Dimmer
The intensity of the line button light can be adjusted by pressing the
button labeled DIM.
1.5.14 Volume Adjustment
By pressing the + or - buttons repeatedly, you can progressively increase
or decrease the speaker volume in the central unit
This will also affect the volume for an external speaker connected to the
panel.
● Press the + button to increase the volume
●Press the - button to decrease the volume
1.5.15 Power Supply SPS-4 (Option)
The power supply SPS-4 is designed with power failure contact and
automatic switch-over relay.
This means that there is an indication and automatic switch-over to 24V
DC emergency power supply when the mains supply or power module
fails.
1.5.16 Audio from External Systems (ETB-10A only)
Entertainment, message or alarm messages can be distributed
through the ETB-10A system.
An potential-free contact and 0 dB signal from the external system
activate the ETB-10A to send the message to all substations.
The TALK button on ETB-10A or the PTT switch on the handheld
microphone will override the external audio.
Normal talk-back functions can not be used in this mode.
The external system may be:
- VHF radio
- Entertainment system
- Alarm system
- Public Address

2 Installation&CongurationProcedures
2.1 General
For proper installation and operation of the ETB system, we recommend
reading this section thoroughly together with technical and connection
drawings in the section 7.
All conguration settings such as volume, foot switch, microphone, etc.
are located on the ETB main board ETB510.
Refer to technical drawings in section 7 Connection/Block/Single Line
Diagrams for more detailed information.
LIn order to comply with DNV ship requirements, this section has to be
followed strictly.
2.2 Mounting
2.2.1 ETBCentralUnit&AmplierCabinetRS-3C
The ETB central unit is the basis of the system. It should be ush or
bulkhead mounted in a normal and ventilated indoor environment with a
temperature of maximum 55 ºC.
Make sure that there is sufcient space for cables and maintenance.
2.2.1.1 IdenticationLabelforETBCentralUnit
A label with the line numbers for all substations should be placed close
to the ETB central unit.
2.2.2 Substations & Other Equipment
See the respective drawings for dimensions, cut-out and mounting of
substations such as STB-1, STB-2, etc.
Make sure that there is sufcient space for cables and maintenance.
2.2.2.1 IdenticationLabelforSubstation
A label with the substation number has to be placed on or close to each
substation.
2.3 Placement of Substations and Loudspeakers
To avoid acoustic feedback, it is recommended to place the 100V
loudspeakers such that they face away from the ETB central unit.

2.5 Cable Requirements
All signal cables have to be approved ship cable of type twisted-pair with
outer braided copper shield.
LSee cable connection diagrams in Section 7 for further details.
The screens must be interconnected in junction boxes and grounded in a
common point in the central unit only.
Terminal block K1 – K10 no. 5 is the ground point for each substation
screen.
The power cable must be approved ship cable of minimum 3 x 0.75 mm2.
Maximum cable length = 500 meters
LThe central unit has to be connected to the vessel’s central ground. Proper
grounding is essential for reliable operation.
LEnsure that signal cables are separated from power cables.

2.6 Power Supply Requirements
● 24 VDC -10% + 33% (21.6 – 32 VDC)
● Current consumption max. 2A
System power supply should be wired and fused independently from
other systems:
● 24V DC from ship’s 24V DC system.
● 24V DC from power supply SPS-4 230V AC / 24V DC with automatic
switch to 24V DC emergency power supply.
2.7 Volume Adjustment for Substation Lines
System volume for substations can be adjusted by separate trimmer for
each group of 5 lines: master volume lines 1-5 and lines 6-10.
Volume is factory set and does not normally require any adjustment.
If the installation on some locations requires another sound pressure
level, this can be changed to the desired audibility and volume.
2.8 Extra Signal Device
The maximum load for each substation line is 50 mA to substation with
relay unit or signal device (connected on terminal block K1 – K10 no.
3-4). The maximum load from substations STB-3 and STB-5 is 2A.
2.9 Foot Switch for ETB Central Unit
The foot switch is used together with the ETB central unit and gooseneck
microphone.
When the foot switch is used, the jumper labeled JUMPER FOR FOOT
SWITCH on the main board has to be removed.
2.10 Microphone Setup
The jumper J8 has to be set to Microphone.
This is the default setting and does not normally need to be changed.
2.11 Microphone Input Adjustment
Input for microphones can be adjusted via the potentiometer labeled P1.
The input level is factory set and does not normally require any
adjustment.

3.1.1 Making a Call to a Substation
You can select the substation by pressing the desired line push button.
A steady green LED will indicate the activated line.
If desired, the signal button SIGN may be pressed to send a tone signal
to the selected station. Pressing the TALK button enables talking from
the ETB central unit. The central unit will be in listening mode as soon
as a station is selected. To terminate the communication, press the
selected line button again. The LED will stop being lit to indicate that the
selected line is terminated.
●Press the line button
- the call is set up, indicated by a steady green LED
●Press the SIGN button
A tone signal will be activated at the selected station as long as the SIGN
button is kept pressed.
This will also activate an extra signal to substations equipped with these
devices.

●Press the TALK button
● Speak clearly into the microphone
When the TALK button is released, the ETB will be in listening mode and
you will hear the communication from the selected station in the panel
loudspeaker.
