2.4. Functions & User Facilities.
2.4.1 General
The CTB-100 system consist of 1 central unit CU-100 or Cu-200, 1 to 4 operation panels, 1 to 20 substations or
loudspeakers and one 100V power amplifier. On system with more than 1 operation panel, each panel take one
substation line. The system have one speech channel and operation from one operation panel will be indicated in
other operation panels. The operation panels follows a priority hierarchy 1 to 4, that means operation panels with
higher priority can override operation panels with lower priority.
Operation panel CTB-10 & CTB-10W_V01 with 10 line selection, CTB-20 & CTB-20W_V01 with 20 line
selection. CTB-20 used in the presentation.

HP-8.
Note ! Make sure that it is sufficient space for cables and maintenance.
3.2.4 Identification sign plate CTB-panels
A sign plate with directory / substation number for all substations has to be placed close to the CTB-panels.
3.2.5 Substations and other equipment.
Ref. datasheets for dimension, cut out and mounting.
Note ! Make sure that it is sufficient space for cables and maintenance.
3.2.6 Identification sign plate substation
A sign plate with each substation number has to be placed on or close to each substation.
3.3 Cable requirements
All signal cables have to be approved ship-cable of type twisted pair with outer braided copper screen.
See cable connection drawings in chapter 6 for further details.
The screens must be interconnected in junction boxes and grounded in the central unit only.
Terminal block X8 1-20 terminal no.5 is ground point for each substation screen
Terminal block X1,2,3,4 / no.11 is ground point for each operation panel.
Power cable has to be approved ship cable min. 3 x 1,5mm2
Note! The central unit has to be connected to the vessels central ground.
Proper grounding is essential for reliable operation.

3.4 Power supply requirements
24VDC -10% + 33% (21,6 – 32VDC) Current consumption max. 4A
System power supply should be wired and fused independently from other systems.
1. 24V DC from ships 24V DC system.
2. 24V DC from power supply SPS-4 230V AC /.24V DC with automatic switch to 24V DC emergency power
supply.
3.5 Set priority in CU-100 & CU-200
Ref. drawing CU-100_lo and CU-200_lo
DIP-switches in the central unit.
Priority is set by 4 dip-switches, corresponding to each operation
panel 1 to 4.
If all 4 dip-switches is set to off, the priority follows a hierarchy 1
to 4 giving panel 1 highest priority.
This is standard factory setting.
What ever DIP-switch set to 1 will have highest priority, still
following the hierarchy as explained above.
Example: If DIP switch 4 is set to ON, priority will be 4-1-2-3.
If both DIP switch 1 and 4 is set to ON, priority will be 1-4-2-3.
3.6 Set receive-call from substation.
Ref. drawing CU-100_lo and CU-200_lo
Receive call from substation is set by 4 DIP-switches,
corresponding to each operation panel 1 to 4.
DIP-switch set to ON, permits the panels to receive a call from
substations.
DIP-switch 1 is set to ON for panel 1 is standard factory setting.
Example: If both DIP switch 1 and 4 is set to ON,
both panel 1 and 4 will receive a call.
3.7 Set public address zones SPA
Ref. drawing CU-100_lo and CU-200_l
Four line push buttons on the operation panel can be set to access 1
up to 4 public address zones.
PA is set by 4 DIP-switches corresponding to each push button.
DIP-switch marked 7-10 for line 7 – 10
(CTB-10 & CTB-10W_V01)
DIP-switch marked 17-20 for line 17 – 20
(CTB-20 & CTB-20W_V01)
Standard factory setting is to OFF.

3.8 Volume and signal adjustment.
Ref. drawing CU-10_lo and CU-20_lo for location.
3.8.1 Substations
System volume for substations can be adjusted by separate trim potentiometer for each group of 5 lines.
Market “volume setting line 1-5” “6-10” “11-15” “16-20”
System volume is factory adjusted and does not normally require any adjustment.
Volume adjustment for substation line 1 – 5
Trim potentiometer located on mainboard

Trim potentiometer located on mainboard
Volume adjustment for substation line 11 – 15
Trim potentiometer located on additional board CU-20.
Volume adjustment for substation line 16 – 20
Trim potentiometer located on additional board CU-20.
3.8.2 Auxiliary and Public address.
Signal is factory adjusted and does not normally require any adjustment.
Input signal for auxiliary can be adjusted by separate trim potentiometer
marked “adj. aux.input signal”. Required signal 0dB (0,775V)
Signal for Public address can be adjusted by separate trim potentiometer
marked “adj. pa output signal”.
Signal is factory set to 0dB (0,775V) and does not normally require any
adjustment.
3.8.3 Call signal
Signal is factory adjusted and does not normally require any adjustment.
Level of Call signal out all lines can be adjusted by trim potentiometer
marked “adj. call signal out”

4. USER INSTRUCTIONS
4.1 Operation from the operation panel.
Up to 4 operation panels can be connected. Calls can be made from any operation panel to substations.
And calls can be made from any operation panel to another by pressing respective line button.
In this stage the called operation panel act as a substation. Calls from one operation panel will be indicated in
other operation panels. One operation panel is always decided to be a master station with highest priority and can
override operation panels with lower priority.
