INTRODUCTION
The Subcom 2000 Emergency Bell Communication System is designed primarily for emergency back-up to the umbilical wired communications generally used in diving bell installations and would be used in the event of failure of the wired system.
Subcom 2000 is a through water acoustic system and does not rely on the integrity of the bell's umbilical, with its own battery pack being sufficient for twenty hours of operation under normal conditions. The surface receiver unit also has an internal battery pack.
INITIAL INSPECTION
As soon as the system is unpacked, inspect for any damage that may have occurred during transit. Retain all the packing materials until the inspection is complete. If damage is found, notify the carriers and authorised Sonavision Ltd Representative immediately.
PHYSICAL CHECK
This check should confirm that there are no damaged connectors, dents or scratches to the undersea units which might result in excessive corrosion or water ingress.
ELECTRICAL CHECK
Connect the undersea units together as shown in the interconnecting diagram and wire the penetrator cable into the
Bell Internal Unit.
Note the tow wire connection to Bell 24V a.c./d.c. supply is not required for operation of voice communication.
The Bell Battery Pack is shipped fully charged and care should be taken to avoid short circuits. Careful attention must be given to the maintenance of the batteries as instructed in Section 7.4,
Battery Maintenance.
With the Transducer connected to the Bell External Unit a strong signal should be heard from the loud-speaker on scratching the
Transducer surface.
A similar test with the Surface Unit should be conducted.
Final Functional test may be carried out by immersing both sets of transducers in a bucket of water or by smearing the face of each transducer with silicon grease and connect them face to face bonded by the silicon grease. Then verify that two way speech communications is possible.

SYSTEM DESCRIPTION
OVERVIEW
The Subcom 2000 System is a wireless acoustic underwater communication system designed for emergency backup communications between a Diving Bell and its surface support.
The communications system operates as standard on 27kHz
SSBSC, compatible with present submersible equipment.
Transmit power is 10 Watts rms on communications.
All bell electronics and batteries are housed in an external pressure housing, which results in greater safety and increased reliability as helium ingress cannot occur and high internal humidity problems do not exist. Only a minimum amount of bell-space is occupied by the small Bell Internal Unit which houses an 8 ohm loudspeaker which also serves as a microphone.
The Surface Unit is provided with a variable squelch control for use in noisy environments. This facility also helps to conserve battery power.
Automatic gain control is provided on both Surface and Bell
Units, with manual variation of gain also being possible on the
Surface Unit.
The system also features the normal advantages of Single
Sideband Suppressed Carrier working (SSBSC) as opposed to
Double Sideband (DSB). For the same audio bandwidth the noise bandwidth is halved giving a 3dB reduction in noise in an
SSBSC system. Additionally, all the transmitted power is audio information in SSBSC system, whereas in a DSB system half the power is wasted in transmitting an additional sideband containing no extra information.
The Surface Unit contains an internal 24V rechargeable battery pack and integral charger unit. The batteries may be charged through the charge input socket. This should not be connected during normal operation as it will reduce the transmitted power.
The Bell Unit has an external 24V battery pack which can be recharged by the charger provided. This should be done by disconnecting the cable between the Bell Battery Pack and the
Bell External Unit at the Electronics Housing and connecting this to the charger.
At monthly intervals allow both surface and subsea battery packs to fully discharge by leaving the systems switched on.
The subsea battery may be discharged more quickly be connecting a 22 ohm wire-wound resistor (rated at 50 Watts and mounted on a metal heatsink) to the battery for up to four hours

depending on the initial state of charge. Discharge ought to be stopped when the voltage reaches 20 Volts. Take care not to leave such a load connected after normal discharge, otherwise the battery pack may be driven into DEEP DISCHARGE and be
PERMANENTLY DAMAGED.
CONTROLS - BELL INTERNAL UNIT
VOLUME: This control is used to switch ON the Bell
Unit communications and the Strobe Light and to vary the volume of the received communications. When switched on the unit is normally on receive.
PTT: This control when depressed, switches the
Bell Unit to transit mode, enabling speech to be input to the Bell Internal Unit speaker which is configured as a microphone.
STANDBY: In the UP position, this switch allows normal received operation of the system to be controlled by the ON/OFF
VOLUME control. In the STANDBY position, it enables the Power Fail Detect
Circuit to operate. This facility monitors the bell supply (24V d.c. or a.c.), so that if a power fail occurs, the Bell Unit is automatically activated communications and strobe. giving
NOTE: If the Bell supply is not connected the
STANDBY position should not be used.
PING AUX: In the ON position, this switch will enable the auxiliary emergency systems optional Strobe Light to be activated when either: a) The communications channel is opened up by virtue of the power fail detection circuitry operating. b) The ON/OFF VOLUME control is turned to the ON position. In the OFF position the
Strobe is disabled.
AUX SPEAKER: This is a jack socket which when utilised will disconnect the speaker mounted in the control box and allow another suitable loudspeaker of 8 ohms impedance to be connected.

BELL SUPPLY: This is a gland situated on the side of the Bell
Internal Unit which allows entry of the 24V supply required by the power fail detect circuitry. This is purely a monitoring function and is not required to power the
Bell System. The External Battery Pack is supplied to power the system since the effects of supply-borne interference is minimised and battery capacity can be more accurately estimated with only one power supply.
CONTROLS - SURFACE UNIT
FUSE: Holder for system main fuse 1.25 inch 5 amp.
VOLUME: This acts as the overall system power switch and speech volume control. When switched on the unit is normally on receive.

THEORY OF OPERATION
The basic circuitry of the Subcom 2000 System is identical for both Surface and Bell Units and the following technical description will apply to both units.
The Subcom 2000 is an SSBSC transceiver operating on the upper sideband of a 25kHz crystal controlled carrier. The system is composed of five basic units, as follows:
Receiver
Acoustic sound pressure waves are sensed by the Transducer which converts them into electrical energy. These signals are fed to the input of the receiver. The signals are amplified by the high frequency (27kHz) front end section of the receiver. The high frequency section of the receiver contains the automatic gain control (AGC) element of the receiver which will be referred to later. The amplified signal from the high frequency section of the receiver is then connected to the bandpass filter where the signal is band limited to remove noise and provide improved selectivity of received signals.
The signal is then fed to the chopper mixer circuit where it is mixed with a 25kHz signal from the crystal oscillator. This process produces sum and difference frequencies between the received signal and the crystal oscillator. The difference frequency is then filtered out by the lowpass filter which follows the mixer circuit. This audio signal is now coupled to the
Preamplifier which, after amplification, couples the signal to the volume control where its level can be adjusted before going to the audio power amplifier and AGC amplifier, which further amplifies the audio signals and converts it to a d.c. level for the purpose of controlling the gain of the receiver high frequency front end.
Transmitter
Upon pressing the PTT switch, audio signals from the device acting as the microphone (ie. a fist microphone loudspeaker or boom microphone) will be coupled to the microphone amplifier circuit. This signal is then mixed with a signal from the crystal
3400-31-0016 Page 14 of 53
4.4.3
4.4.4

Sonavision Ltd.
Aberdeen, Scotland
oscillator by the chopper mixer circuit. This produces both an upper and lower sidebands. The bandpass filter then selects the upper sideband signal which is coupled to the power amplifier which drives to the Transducer.
Filter, Mixer and Oscillator
The filter circuits extract the bandwidth of frequencies utilised by the system. These signals are mixed with a 25kHz ±0.01% signal from the oscillator circuit by the mixer circuit.
Voltage Regulator and Electronics Switch Circuits
The voltage regulator produces a 12V regulated level from the
24V unregulated input. The 12V level is fed to the receiver or transmitter by the electronic switch circuit as controlled by the
PTT switch. The power amplifier circuit also uses the unregulated 24V supply direct.
Transducer
A bi-directional device used to convert electrical energy into acoustic energy and acoustic energy into electrical energy.
Inadequate separation between Transducers on the ship for communications or any other purpose is the major likely cause of system interference.

INSTALLATION
SURFACE UNIT
The Surface Unit is fully self-contained and may be operated from any location on the support vessel.
The charge cable supplied identifies the power connection, and only one of these should be connected as required. (Take great care not to let the free ends of this charging cable short together otherwise damage will be caused to one of the relays in the power module. Keep the leads insulated except when being used).
The TAPE/UNSC cable should be terminated as required for the appropriate equipment used.
Careful consideration should be given to the Surface Transducer deployment, especially with regard to other acoustic transducers on the ship, ie. dynamic positioning systems, echo sounders, etc. The communication transducer should be placed as far from these other sources as physically possible.
The communications transducer (27kHz) should be run out to full cable length and should be at least fifteen metres below the support ship.
BELL INTERNAL UNIT
The Internal Bell Unit should be mounted by means of the mounting holes provided at about head height within the bell.
Connections are required to the Bell External Unit via an 8 way penetrator assembly.
Cable Assembly continuity from the 8 way Kintec should be tested and each termination identified prior to installation. This cable should then be fed into the Bell Internal Unit via the side entry cable gland and terminated as shown on the Subcom 2000
System Bell Equipment Interconnection Diagram.
An auxiliary speaker output is provided by means of a covered jack socket on the unit.
A cable entry gland is provided so that a feed of 24V a.c. or d.c. from the umbilical bell supply can be sensed inside the Bell
Internal Unit. This is used to automatically activate the emergency communication circuits and auxiliary systems in the event of this voltage being removed for whatever reason whilst the system is in STANDBY mode. When this occurs, the Strobe
Light if fitted will be activated, provided that the PING AUX and
STANDBY switches are in the ON position. Signals to the bell will be enabled and low volume speech will be reproduced by the loud-speaker until such time as the volume control is turned up manually. If the system has been turned on in this automatic

manner it is necessary to physically turn the ON/OFF VOLUME control to the ON position before starting to transmit from the
Bell Internal Unit.
BELL EXTERNAL UNIT
The External Electronics Housing (identified by having three bulkhead connectors) should be mounted anywhere suitable on the bell bumper bar with the Bell Battery Pack in a separate housing being located in close proximity. Extreme care should be taken when mounting these units to prevent damage to the anodic coating.
The Transducer should be mounted towards the top of the bell.
The battery unit should be connected to the Electronics Housing via the 3-way Power Cable Assembly provided. The penetrator cable assembly should be connected to the 8-way bulkhead connector, and the transducer to the 4-way bulkhead connector.
The cap screws which secure the lids to the housing should be periodically checked for tightness, particularly after transit.

COMMISSIONING
Switch the Surface Unit ON, and check that the front panel indicator is illuminated. Turn the squelch control to the OFF position and turn the volume control clockwise. Scratch the
27kHz communications transducer and a scratching sound should be heard from the speaker (or headset if fitted and the
SPEAKER/HEADSET switch is in the HEADSET position).
Rattling a set of keys near the transducer will produce sufficient acoustic energy to be reproduced quite clearly.
To talk from the Surface Unit to the Bell Unit, put
SPEAKER/HEADSET switch to the SPEAKER position and press PTT on the hand microphone to talk. If a headset is being used this switch should be in the HEADSET position.
Transmission can also be achieved by talking into the speaker on the Surface Unit with the switch in the SPEAKER position although the quality and clarity of the communications is degraded when this contingency feature is employed. A spring biased PTT switch is provided on the front panel to enable this facility to be used if required.

SERVICE
To minimise operational downtime of the system it is recommended the spare parts listed under operational spares be carried on the support vessel while the more comprehensive list of major items should be held at a shore base, where maintenance and repair work is normally undertaken. The third list gives details of some of the more critical components required to maintain full operational status. Reference should be made to the parts list section for comprehensive details of components used.
Extensive stocks of all components used in the Subcom 2000 are held by Stenmar Sonavision Ltd and are available on a twenty-four hour basis as are our fully experienced field service engineers.

BATTERY MAINTENANCE
Surface Unit Batteries a) Charge for twelve hours from discharge state. Indicated by power ON indicator changing from green to red.
Connect charge lead to either mains supply or 24V d.c.. b) The batteries should not be charged with system operating. c) Normal continuous operation on a fully charged battery should exceed twenty hours. d) Mains input to the charger's transformer may be selected to be either 115V or 240V a.c. by internally wiring the appropriate tags on the transformer.
Bell Unit Batteries a) Charge batteries using the constant current charger provided. The required a.c. mains voltage for which the charger's transformer has been set is indicated by a label on the charger case. If required this setting may be changed by internally wiring the appropriate tags on the transformer. b) Charge batteries for fourteen hours from fully discharged state, and proportionally less from a charged state.
NOTE: The charging rate of 400mA has been chosen such that no damage should occur if the batteries are left on charge for an extended period of time. This serves no useful purpose after the batteries have acquired their full charge and the practice is not advised. c) Normal continuous operation on a fully charged battery should exceed twenty hours, although this will depend on the amount of time spent transmitting, and on the use of the Strobe Light. d) Care must be taken to avoid shorting the battery terminals. Should this happen the internal fuses may blow. Replacements are 10 amp, 1.25 inch normal blow fuses. Replacement fuses for the Strobe Light are 1.25 amp, 1.25 inch anti-surge fuses. e) At regular intervals (two-four weeks) allow batteries to fully discharge to a terminal voltage of 20V. This may be done by leaving the system switched on or by connecting a dummy load of 22 ohms, 50 Watts rating for period of up to four hours. Monitor the terminal voltage of the battery pack and stop discharging when voltage has

f) fallen to 20V. (The second battery connection provides a convenient voltage monitoring point).
Since both terminals on the battery pack are wired in parallel either terminal may be used for charging. g) The vent valve should be slackened during charge cycles but must be resealed prior to immersion.

OPTIONS
STROBE LIGHT
The Strobe Light option on the Subcom 2000 Bell Emergency
System gives a switched strobe facility for emergency location of the bell.
The strobe emits a high powered flash once every three seconds and is powered directly from the system battery pack.
It is switchable from inside the bell by means of a switch on the
Bell Internal Unit.
To avoid radiation interference it is important that during installations the Strobe Light be separated as much as physically possible from the bell communications transducer.
The strobe may be switched off using the PING AUX switch provided on the Bell Internal Unit.
