MB4 – Manual bracket. FBH4 – Automatic float free bracket v/ Heating. The JOTRON Tron 40S EPIRB is developed to meet the regulations and rules for use on vessels and life rafts in the maritime service.Tron 40S meets the following specifications for 406 MHz EPIRBs for use in search and rescue operations at sea:  ETS 300 066  MPT 1259  C/S T.001  IMO A695 (17){1}  IMO A810 (19) The Tron 40S is buoyant, and is designed to automatically release and activate in case of an emergency where the EPIRB and its bracket is submerged into the sea.The Tron 40S can also be operated as a manual EPIRB. Three mounting brackets are available to mount it either as an automatic or manual only EPIRB.The purpose of the Tron 40S is to give a primary alarm to the search and rescue authorities.The EPIRB gives an immediate alarm when activated, transmitting the ID of the ship in distress. Care must be taken not to activate the EPIRB unless in an emergency situation, in such cases the user will be held responsible. For periodic testing a test function is implemented. During the test cycle the EPIRB does a selftest on the transmitters and on the battery status. No emergency signal is transmitted during the selftest.The battery of the EPIRB will last for at least 48 hours from activation of the EPIRB. OPERATORS MANUAL 14 1.2SYSTEM DESCRIPTION The COSPAS/SARSAT system was introduced in 1982 as a world-wide search and rescue system with the help of satellites covering the earth’s surface. Since the introduction of the system more than 5500 persons have been rescued by the COSPAS/SARSAT system (June 1995). Currently the system consists of 6 different satellites in a polar orbit constellation, these satellites cover the entire earth’s surface and receive the emergency signal from the 406 MHz transmitter within the Tron 40S, more polar orbiting satellites will be available in the future, giving a faster location and rescue time. In addition several geostationary satellites are equipped with a 406 MHz transponder, these satellites are not able to locate the Tron 40S but will give an early warning to the rescue forces, minimising the time from an emergency occurs till the rescue forces are at the site. Each emergency EPIRB in the system is programmed with its own unique code, therefore it is vital that the ships data that is given to the dealer you obtained your Tron 40S, is correct. It is also important that your EPIRB is registered in the database for each country.This database is normally located in the same country that the ship is registered. 1.3SIGNAL DETECTION [FIG.1] When the Tro…

Introduction 1.1. The Jotron Tron 40S EPIRB was assessed in early 1999 by the US Coastguard and certain observations were made about the labelling and activation mechanism. Letter from Mr B Markle of the USCG dated 22 February 1999 refers. 1.2. This report details the changes that Jotron Electronics AS, have made to improve the activation and comply with the observations of the USCG. 2. Equipment under Inspection 2.1. Jotron Ltd supplied the following items on 16 Dec 99 for the duration of type testing at the DERA Fraser Test Laboratory. This inspection and the photographs contained in Annex A were taken in April 2000 once the beacon had completed testing. ITEMTypeID Number 406 MHz EPIRBTRON 40S9KP05404 Foat free bracketFB44507 3. Configuration of the EPIRB sample 3.1. The beacon was built to production standards. 4. Form of activation 4.1. Since EPIRB Beacons are capable of accessing global emergency services and will trigger search and rescue activities in the location reported, they are required to be equipped with a form of activation that minimises the likelihood of false alarms. 4.2. In the opinion of the USCG the original form of activation did not constitute the "two independent actions" required by IMO Resolutions. Jotron Electronics AS, have revised the activation mechanism and the new form of activation is as described below. Photographs were taken at each stage of the activation to illustrate the procedure, these can be found adjacent to the referenced text. 4.3. EPIRB activation can take two forms, Manual and automatic. Manual activation should be designed to minimise the chance of false alarms and is Required by IMO to involve two deliberate actions by the user. Automatic activation should detect the presence of water when the EPIRB is floating free of the mounting bracket 4.4. The standard condition for the Tron 40S EPIRB beacon mounted in the FB4 float- free bracket are:- COMMERCIAL in CONFIDENCE DERA/SS/CI/TT27/99-2 -1.02 of 6 COMMERCIAL in CONFIDENCE a)manual switch set in "ready" position, split pin inserted through switch to prevent any movement towards the "on" position, wire seal threaded though split pin and adjacent lugs to show non activated. b)automatic, reed switch inside the EPIRB held "off" by a magnet located in the FB4 bracket to inhibit the sea water terminals from reacting to green sea or other conditions of water spash. Photograph 1, shows switch in initial condition. 4.5. The first stage of activation is to break the wire seal, this can be done by twisting and pulling on the wire/orange seal. The split pin is then pulled up by the chain and removed from its hole the pin will stay attached via the chain. Photograph 2, first stage activation completed, note lever does not move. COMMERCIAL in CONFIDENCE DERA/SS/CI/TT27/99-2 -1.03 of 6 COMMERCIAL in CONFIDENCE 4.6. The major component redesigned by Jotron Electronics to improve the switch action is the orange, lever slide. This now has a spring section to the left hand side of the lever which latches against the black housing and stops the lever from moving into the "on" position. Photograph 3, shows lever slide, sprung section latched against black housing. 4.7. Pressure on the spring section (marked "Push") will allow the lever to move into the "on" position. Photograph 4, shows thumb applying pressure to lever slide. COMMERCIAL in CONFIDENCE DERA/SS/CI/TT27/99-2 -1.04 of 6 COMMERCIAL in CONFIDENCE 4.8. The lever is spring loaded and once un-latched will automatically move to the "on" position. Photograph 5, shows lever slide in the "on" position. 4.9. The lever is also used to access the test facility and at any time may be moved into the test position, even if the split pin is still inserted. It has to be held in the "test" against a spring loading that will return it to the "ready" position when released. Photograph 6, shows lever slide in the "test" position. COMMERCIAL in CONFIDENCE DERA/SS/CI/TT27/99-2 -1.05 of 6 COMMERCIAL in CONFIDENCE 5. Conclusions 5.1. The activation mechanism of the Tron 40S EPIRB has been inspected as detailed in this report and is considered to meet the requirements of the IMO Resolutions A812(19), appropriate parts of A814(19) and RTCM Paper 4-97/SC110-STD Clause 2.3.1.2.…

Introduction 1.1. The Jotron Tron 40S EPIRB was partially tested in accordance with the RTCM Recommended Standards for 406 MHz Satellite Emergency Position-Indicating Radio Beacons (EPIRBs) RTCM SC110. [1] 1.2. This beacon type had previously been tested to COSPAS SARSAT Standard T.0007 by CNES. [2] and to MPT1259 by DERA [3] 1.3. The test laboratory at DERA Fraser has been accredited by UKAS under their NAMAS scheme and is a UKAS accredited Testing Laboratory No. 1217. 1.4. The Jotron 40S EPIRB is designed to operate in the temperature range -20 o C to +55 o C (class 2) and is float-free automatically-activated (category 1). 1.5. Opinions and interpretations expressed herein are outside the scope of UKAS accreditation. 2. Equipment under test 2.1. Jotron Ltd supplied the following items on 16 Dec 99 for the duration of type testing. ITEMTypeID Number 406 MHz EPIRBTRON 40S9KP05404 2 additional Battery Packs-- Additional body with connector-- Foat free bracketFB44507 2.2. Photographs of the EPIRB can be seen in Annex A. 3. Test Location 3.1. The tests were executed at DERA Fraser, Fort Cumberland Road, Portsmouth, Hants. 4. Configuration of the EPIRB sample 4.1. For several of the tests the beacon required the beacon to be connected to the measuring equipment. This required a 50 ohm output from the beacon however the connector was not waterproof. For the tests that required the beacon to be totally immersed in water the beacon was configured with the standard upper body. For the other tests the beacon had the upper body replaced by one with a connector. An internal lead connected the output to this connector and the antenna was disconnected. COMMERCIAL in CONFIDENCE 2 of 24DERA/SS/CI/TT27/99-1.0 COMMERCIAL in CONFIDENCE 4.2. The changing of the configuration was carried out by DERA test engineers. 5. Tests 5.1. The Jotron 40S had previously been tested to COSPAS SARSAT T.007 and MPT 1259 and has been granted UK type approval. An application for type approval by the US Coastguard was rejected as the previous testing was not appropriate to RTCM SC110. (see letter dated 22 Feb 99 in Annex C). A proposed test plan was produced by DERA (see fax dated 29 Sept 99 in Annex C). The US Coastguard response to this (see faxes dated 8 Nov 99 & 10 Nov 99) was that all tests numbered 1 to 12 of the schedule of RTCM SC110 were required. A further exemption was that only a subset of the COSPAS SARSAT tests (number 11) need to be done. This subset consisted of the digital message generator and modulation tests only. 5.2. The summary of the RTCM tests is shown in section 7 and the subset of the COSPAS SARSAT tests in section 8. 5.3. An additional check was made on the auxiliary radio-locating device which confirmed that the Sweep Direction was upward. 6. Conclusions 6.1. The Jotron 40S EPIRB was tested and found to meet the requirements of RTCM Paper 4-97/SC110-STD in aspects as detailed in this report. 6.2. The Jotron 40S EPIRB is recommended for type approval as a class 2 category 1 beacon.

One selftest takes approx. 15 sec. The current consumption in selftest is approx. the same as in operation. If the beacon is tested once every week, this will amount to : 15 sec * 52 weeks * 4 years = 3210 sec's = 52 min. Current consumption in "OFF" mode is less than 0.5mA.
