Normally it is installed on the bridge at the conning position. The Alarm Panel contains three main sections, intended for connection to System 5000 VHF, System 5000 MF/HF equipment, and Inmarsat-C SES equipment. All sections work inde- pendently and all control signals are galvanically isolated by opto-couplers. For Inmarsat-C and VHF, the Alarm Panel has duplicated connections allowing two units of each system to be supported simultaneously. Each section includes a push button for distress alert initiation, and a distress annunciator for indication of distress alert transmission in progress or distress or urgency calls received. Additionally there is an annunciator for indication of equipment type. This is switched on when the appropriate transceiver has been sensed by the Alarm Panel. If a distress alarm is initiated on a system with duplicated units, only one of the units will send the alarm. The selected unit is indicated on the display. To protect against inadvertent activation the distress buttons are protected by spring loaded transparent covers. A button must be kept pressed for 5 seconds before the distress alert is initiated, during which time the audible alarm is beeping and the distress button is flashing. The Alarm Panel is supplied from 24 V DC supply voltage (21 V to 32 V). The input is reverse polarity protected. 4 0715 Technical Data General Illuminated red distress button with transparent cover for each section. Indicator Alarm Panel with distress annunciator and status information for each connected unit. Audible alarm for indication of distress alert transmission in progress, or distress or urgency calls received. Dimmer push button for controlling light intensity in the indicator Alarm Panel. Mute push button for resetting the audio alarm. Test push button for verification of indicators, audible alarm and push buttons. All distress functions work fully independent of each other. All control signals are galvanically isolated by opto-couplers. The indication line in the display goes off if the connection to the associated transceiver is broken. When the connection is re-established it may take up to 20 seconds before it is indicated in the display. Supply Voltage:24 V DC (21 V to 32 V) Current consumption:max.100 mA Operating temperature range:-20°C to +55°C Compass safe distance:Standard: 0.9 m.

The AC Power Supply is designed with four separately fused output lines to ensure independent supply for connected equipment. Furthermore AC Power Supply includes the following features: • 115V/230V selectable input. • Encapsulation class IP22. • Galvanic isolated AC alarm output. • Protected Battery monitoring output. • Easy connection. • Easy access to fuses. • Vertical or horizontal mounting. • IEC 945 approved. 1.2 TECHNICAL DATA AC input voltages: 115V, range 88V - 132V or 230V, range 176V - 264V. Manual setting. AC input frequency: 50/60 Hz ± 6% DC output voltage: 29V ± 0.5V. DC output current: 13A continuous. 17A for 15 minutes. 25A for 1 minute. Duty-cycle 10%. Battery monitoring: Protected output. AC failure output: Relay contacts 5-50mA, 10-32V. Closed in alarm condition. Alarm in case of AC supply failure. Protection: The AC Power Supply output is current limited and protected against short circuit, over voltage and over temperature. Operating temperature: - 20° to + 55° C. Dimensions: HxWxD: 110x370x260 mm. Weight: Approx. 5 kg. Compass safe distance: Standard: 1.4 m. Steering: 1.0 m 0549 1-2 1 Introduction AC Power Supply 0048 2-1 2 Technical Description AC Power Supply 2 TECHNICAL DESCRIPTION 2.1 PRINCIPLE OF OPERATION The AC Power Supply contains an input filter followed by a rectifier (230V)/voltage doubler (115V) circuit producing an unregulated DC voltage which is converted to 29V in a push-pull converter. A regulator optically isolated form the driver circuit then adjusts the output into a constant voltage. The output DC voltage is galvanically isolated from the input and the chassis (ground). The four DC outputs are connected to the battery using it as source if an AC line failure or failure in the unit occurs. As the AC line recovers the AC Power Supply is again source for the four DC outputs. This sequence is controlled by the switch over circuit. 0549 2-2 2 Technical Description AC Power Supply 0048 3-1 3 Installation AC Power Supply 3 INSTALLATION 3.1 OUTLINE AND DIMENSIONS 370mm Mounting, 4 holesø7mm 37670 160mm 260mm 331mm 110mm Cable entry in bottom 350mm 1) 1) 2) 1) 0048 37669 4 screws M5 x 12 4 screws M5 x 12 3.2 MOUNTING POSSIBILLITIES 1) Space for air fl ow min. 200mm 2) Space for cable 250mm 3-2 3 Installation AC Power Supply 3.3 INSTALLATION WIRING 0048 20A - + - + - + 10A10A10A10A10A DC 1 10A +- 20A 30A +- BATTERY CHARGE X4 X5 X9X10X2X1 FLOATMAIN AC ALR LIGHT AC ALR VBAT- DC 2 DC 3 VBAT+ NL X14X13X15 -+ Battery voltage monitor AC alarm Line Neutral Earth 37594 * Max 20A - 29V DC out* Max 10A - 29V DC out* Max 10A - 29V DC out * Max 10A - Emergency light 230/115V AC input Fuse *Note that total output must not exceed specifications 230V/8AT F13 115V/15AT F12 BATTERY CHARGER 3-3 3 Installation AC Power Supply 3.4 BLOCK DIAGRAM INPUT RECTIFIER/ FILTER AC-ALARM CURRENT TRAFO PUSH-PULL STAGE CURRENT FEEDBACK DRIVER STAGE PWM SLOPE COMP.

It also specify how to modify the printer to operate on DC supply instead of AC supply. 1.2 PRINCIPLE OF OPERATION The power supply module is constructed to operate from a battery voltage of 10.5V DC to 32V DC to deliver the necessary voltages for the printer. The voltage conversion takes place in a “flyback” switch converter, which is controlled by a current mode controller. The regulation of the output voltage is controlled via a separate winding of the transformer, which also deliveres the power for the control circuit. At the input and at the output are placed filters to suppress the switch noise.

SAILOR CU5100 MF/HF Radiotelephone USER MANUAL Introduction Congratulations on your new SAILOR CU5100 MF/HF maritime radio telephone with built-in DSC (Digital Selective Calling) system, fulfilling the highest international standards for marine MF/HF communication and safety procedures. The transceiver is born with a 2187,5kHz DSC watch receiver forming an ideal system for MF GMDSS installations. The transceiver can easily be upgraded for 6 channel scanning DSC watch receiver and Telex operation to comply with MF/HF requiements in sea area A3. If connected to a GPS or other maritime navigation system it can automatically include the true UTC time and your position in its DSC distress messages. For an explanation of DSC, see page 2. This SAILOR marine equipment is a part of the modular system 5000 which also includes a HF single sideband radiotelephone. SAILOR marine equipment is specially designed for the extremely rugged conditions on bord a ship, based on more than 50 years’ experience with all kinds of boats, from small pleasure crafts, over fishing boats working under all climatic conditions, to the biggest ships. SAILOR ® is one of the worlds leading manufacturers of maritime radiocommunication equipment - a position which has been maintained by means of constant and extensive product development. We have a worldwide network of dealers with general agencies in more than 80 countries. All our dealers are specially trained to service all your SAILOR ® products.

Distress message is sent at the continuous tone. 4. Unless stopped manually, by pressing the CANCEL softkey or switching the unit off, the distress call is automatically repeated every 3½-4½ minutes until distress acknowledge- ment is received. Wait for distress acknowledgement and start mayday procedure. If an alarm panel is connected the MF/HF DISTRESS button on this unit will have the same functionality. All further handling should continue in front of your main MF/HF DSC. Mayday procedure When DSC distress acknowledgement is received after you have pressed DISTRESS, or if you otherwise need to commence distress traffic via radiotelephony on the distress traffic frequency, follow this procedure: •the distress signal MAYDAY, spoken three times; •the words THIS IS; •the NAME of the vessel in distress, spoken three times; •the CALL SIGN or other identification; •the MMSI if needed; •the POSITION given as the LATITUDE and LONGITUDE or with respect to known geographical location, •the NATURE of the distress; •the kind of ASSISTANCE required; and •any other useful INFORMATION Upon reception of a DSC distress alert from another ship in distress, you should acknowl- edge the receipt by radiotelephony on the distress traffic frequency, by doing the following: •the distress signal MAYDAY; •the words THIS IS; •the NAME of the vessel in distress, spoken three times; •the NAME or other identification of own ship, spoken three times; •“RECEIVED MAYDAY”.
