The EM 406 Beacon Decoder Receiver is capable of Receiving , Demodulating and Decoding Signals from all existing COSPAS SARSAT Emergency Position Indicating Radio Beacon ( EPIRB ) Frequency Channels , Message Formats ( Short and Long ) and Protocols. The EM 406 is Programmable with the Own Beacon's 9 Digit MMSI Number which helps it at distinguishing if the Beacon Burst is received from an Own Beacon or Other Beacon and is capable of Decoding Beacon Bursts that have been transmitted in the Normal ( Live ) Mode as well as in the Self Test Mode. The Detection of a Valid and Error Free Beacon Burst is indicated with an Audible and Visual Alarm clearly indicating if the Burst source is an Own Beacon or Other Beacon. The EM 406 can receive 406 MHz. Radio Frequencies using it's Internal Built - In Antenna or by using an External Whip Antenna to increase the reception range.

 

The EM 406 Main Unit comes with a 20 x 4 Character Liquid Crystal Display ( LCD ) with Backlight , 6 User / Service Interface Keys and Front Panel LED Indicators for Received Signal , Own Beacon Alarm and Other Beacon Alarm. The EM 406 has a Simple Configuration Setup Menu with the Service Setup Menu being Password Protected with a 4 Digit Security Pass Code. The EM 406 is capable of Transferring Serially the Decoded Data to a Computer in Printable Format and is also capable of Logging the Decoded Messages in it's Internal EEPROM Memory. The Date and Time references are taken from the Unit's Internal Real Time Clock ( RTC ) itself or by extracting it from the NMEA 0183 Data from an External GPS ( if interfaced ). The EM 406 can also be used as a 406 MHz. COSPAS SARSAT EPIRB Tester to verify the Signal Integrity and Coding Programmed within the Beacon and is designed such so as to have a Standard 2 Year Calibration Cycle. Beacon Bursts detected containing Framing / Data Errors are indicated with an Error Message.

 

With an accidental or inadvertent transmission of a Beacon Distress Signal whether from own vessel or from another vessel within immediate vicinity and in visual range , the local Rescue Co-ordination Centre ( RCC ) can be contacted immediately and informed of the co-ordinates of the Beacon site hence preventing unnecessary initiation of expensive Search and Rescue ( SAR ) procedures. The installation of such an equipment is a relatively low - cost and an effective means of avoiding the disruption of shipping activities and rescue services and possibly substantial fines imposed on the Ship Owners in the event of the transmission of a False Distress Alert.
