VSP 12-Way Batteryless Telephone System
Technical Manual
1 General Description
1.1 System
The VSP Amplied Batteryless Telephone System is designed for
safe, loud and clear communication, and as a replacement for the
conventional Sound Powered Telephones.
The conventional facilities are retained and a low power consumption
amplier with capacitor-battery ensures excellent communication.
Through the use of dynamic microphone- and receiver-inserts, speech
and hearing levels that are 4 times louder can be obtained as compared
to the Sound Powered Telephones.
The VSP system is independent of the vessel’s power supply and fullls
the demands for emergency communication between vital locations
onboard.
The VSP system described in this manual is a system comprising up to
12 main stations with selector switches for selective calling between all
connected stations. The VSP system can also be connected to a 24V
DC power supply and work as a Common Battery Telephone System.

2.1 Power
● An AC voltage appears between TP10/TP11 and TP12/TP13 when
the hand crank is activated. This voltage is rectied in D19 and D21,
providing DC power for two purposes:
- Powering the amplier
- Creating a call signal
LP8 and P9 together with D17 enables the use of the board with the old inductor.
● When a call is being made, the actual line will carry a generated
voltage. This voltage is fed through the active line via the
corresponding diode D11 and D12 to the amplier.
● A permanent amplier 24 VDC power can be supplied on the
connection block terminal 23 (+) and 24 (-).
LTo avoid noise problems, the 24 VDC power supply must be connected via a DC/
DC converter.
LNote that the circuit boards can be used as spare parts for the older VSP units.
When using boards with inductors, remove jumpers from pins J6 and J7/J8 and
insert a jumper on pin J9 located to the left of the DIP switches.
2.2 Calling
● The station’s extension number is set by DIP switches P11 - P22.
This will activate the call signal generator in the called station and
provide power to the amplier.
● The desired station is selected by a 12-way rotary switch.
When turning the hand crank, a voltage is supplied to the selected
line.

2.3 Amplier
Only the Main Station VSP-211-L has a built-in microphone amplier.
This amplier is used by all stations in the system.
● The capacitor C7 will be charged and act as the battery power for the
transistorized amplier.
- The voltage across C7 is limited to 39 VDC by the Zener diode Z1.
- The voltage will slowly decrease to less than 20 V during a period
of 15 to 20 minutes. Despite the change in voltage level, full
amplication will be obtained during this period.
● The amplier quiescent current can be measured by replacing the
strap P6 with a uA-meter.
- The quiescent current is set to Iq = 20 uA at U = 20-30 V when
delivered from the factory and can be adjusted by RV1.
2.4 Call Signal
2.4.1 Stations for Use in Safe Areas
● The oscillator will start when the hand crank is activated and the DC
voltage exceeds Zener diode Z2 limitation (30 V).
- A call tone will be heard in the handset microphone both at the
calling station and the station being called. (In this case, the
dynamic microphone acts as a ‘loudspeaker’).
- The calling tone frequency is 2500 Hz.
It is not recommended to change the call tone frequency because it is
adjusted to the mechanical resonance of the handset.
The call tone has a uttering frequency at about 15 Hz because of the
crank speed.
Depending on environmental noise, it is possible to choose a high or low
level for the call tone by strapping P7 on the station PCB.
2.4.2 Stations for Use in Hazardous Areas
● No call signal is supplied in EX approved stations (VSP-512) used in
hazardous areas.
- Calls to a station in a hazardous area will be indicated by use of EX
approved audible or visible signal units.
- When VSP-512 is called, a relay in the bu󰀨er unit will be activated
and necessary power for the signal devices will be supplied.
2.5 Handset
The microphones in all stations are connected to the same line when
their handset button is pressed. This line is connected to the input
transformer of the system amplier located in VSP-211-L.
The microphone line is marked 1 and 2 on the screw terminals in all
VSP units.
The speakers in all station handsets are connected to the same line
when the handset button is pressed. This line is connected to the output
transformer of the system amplier located in VSP-211-L.
The speaker line is marked 3 and 4 on the screw terminals in all VSP
units.

3 Installation
In a VSP system, one station MUST BE a VSP-211-L where the
transistorized amplier is located. This amplier is used by all stations.
The other stations in the system can be any other VSP station type,
depending on the requirements and environments.
3.1 Connection
All stations in a VSP system are connected in parallel, i.e. all terminals
with the same number are linked together in all stations.
Some stations have additional terminals for station type related
connections.
All VSP stations
General screw terminal block numbered from 1 to 16.
Microphone line 1 (signal) and 2 (ground)
Speaker line 3 and 4 (balanced)
Station lines 5 to 16 (lines 1 to 12)
VSP-223-L station
This station has a built-in latch relay circuit for activating external
audible and/or visible signal units. Additional terminals 17-22 are added
for this feature.
Local 24 VDC for signal unit 17 (+24 V) and 20 (0 V)
Signal unit connection 18 (+24 V) and 19 (0 V)

VSP-211-L station
The VSP system can also work as a common battery telephone system
when an external 24 VDC power supply is connected to the system
amplier. Two terminals are added for this purpose.
External power in 23 (+24 V) and 24 (0 V)
3.2 Cabling
The recommended cable is 0.5 sq. mm revolved in pairs with an outer
insulated screen, like RCOP.
The number of wires needed depends on the number of stations in the
system.
● Two twisted pairs are used as microphone (1 pair, terminals 1 &
2) and speaker (1 pair, terminals 3 & 4) lines. In addition, one wire
is used for each station selection. A full system with 12 stations
therefore requires 8 pairs of wires.
●The screen must be connected to terminal 2 in VSP-211-L to avoid
noise problems.

3.3 Compass Safety
The station units must be installed at least 155 cm away from the
vessel’s magnetic compass.
3.4 Setting Extension Number
Each VSP station must have its own extension number, 1 to 12, set by
DIP switches.
To set the extension number:
1. Insert jumpers into pins J2 and J3.
2. Activate the DIP switch on the PCB corresponding to the selected
number by sliding it to the ON position.
Figure 4: DIP switch setting for extension no. 2
For information on all extension number settings, see section 7 DIP
Switch Settings for Extension Numbers.
A label strip with numbers 1 to 12 is shipped with each station.
● Fix the label with the relevant extension number in the frame next to
the text Station no at the front of the station.
