HOW THE TRON 40S SAVES LIVES The SARSAT/COSPAS system was introduced in 1982 as a worldwide search and rescue system with the help of satellites covering the Earth’s surface. Since the introduction of the system, more than 100,000 people (Dec 1998) have been rescued by the SARSAT/COSPAS system. Each emergency beacon in the system is programmed with its own unique code. Therefore it is vital that the ships data given when you register your Tron 40 GPS is correct. It’s also important that your beacon is registered on the database for each country. This database is normally in the same country as the ship is registered. The Tron 40S will be activated and immediately start to transmit vessel identity and positioning signals to the SARSAT/COSPAS satellites if: – the vessel sinks. Then the EPIRB will be automatically released from its bracket when subjected to waterpressure at 2-4 metre depth, and then float up to the surface. Due to the function of the seawater contacts it will transmit. – –if a controlled distress situation allows and the Tron 40S can be taken out of the bracket and manually activated by breaking the seal and pulling out the safety pin. The satellite forwards the signal to a ground receiving station (LUT) where also the position will be calculated and transferred to a Mission Control Centre (MCC). The necessary commands will be sent to the right Rescue Control Centre (RCC) which co-ordinate the rescue operation. The search and rescue forces (SAR) brings the distress to safety and deactivates the Tron 40S. The necessary command will be sent to the right Rescue Control Center (RCC) which coordinate the rescue operation. The Search And Rescue forces (SAR) brings the distress to a satisfactory conclusion and deactivates the Tron 40S. Since the inception of the SARSAT COSPAS rescue system and initial field trials in 1983 Jotron has played a leading role in proving the system viability and since the introduction of mandatory carriage requirements has enjoyed a volume supply position from which, in maritime distress situations, countless lives have been saved. The Tron 40S offers manual and automatic activation, is physically small and can be mounted anyway up. TO TEST the Tron 40S is very easy. Just press the switch to the test position. Follow the test procedure. Programming is also easy due to a new infrared programming system. All decoding and programming can be done without opening the unit just by holding the programmer/decoder towards the programming points externally. The Tron 40S is designed to follow the well known Jotron safety maintenance and service program. Every 4th year, the battery should be exchanged and every 8th year the whole unit together with the bracket should be serviced or exchanged. Due to the availability of more than 160 service stations worldwide (Jan. 2000) you will have your Jotron safety equipment in the best shape and ready to use all the time. The Tron 40S is designed to be installed in the manual MB-4 bracket. Or a FB-4/FBH-4, which is a float free automatic release bracket may be used.

The FB-4/FBH-4 allows you also to release the EPIRB manually by pulling out the locking pin.The brackets are equipped with safety switches to avoid false alarm as long as the Tron 40S remains in the bracket. H-20 Hammar hydrostatic release mechanism to be used with modified Jotron bolt. The Tron 40S will automatically be pushed out from the bracket due to the built-in reusable catapult spring. This is installed to ensure that the EPIRB will leave the bracket after the H-20 “Hammar hydrostatic release mechanism” has been activated.
