An Emergency position indicating radio beacon has the following features: Emitting two types of distress signals: 406.028 MHz and 121.5 MHz. The EPIRB main unit attached to the automatic release bracket is automatically released within water depth. 4 meters and sends two types of distress signals. After release from the automatic release

The HydroFix™ HRU Kit is a universal kit in that it is used for Category I ACR EPIRBs. The kit components that are required to replace the HRU in a particular model will vary with the EPIRB bracket you are servicing. The content of the universal HRU kit includes the following: Figure 1 items: A Category I bracket (SeaShelter™ or SeaShelter™ 2

PRU-50 is a USB powered programmer which can be used to program Jotron’s: • EPIRBs • Handheld VHF (Tron TR20) • ML-series of lights. Technically, this unit converts signals from virtual COM ports on a computer (through a USB-serial adapter built into PRU-50) into infrared light which is used to communicate with EPIRBs or programmable lights.

(2) Each EPIRB and each SART other than an EPIRB or SART in an inflatable liferaft, must be tested monthly. The EPIRB must be tested using the integrated test circuit and output indicator to determine that it is operative. (f) Annual inspections. Annual inspection and repair must include the following:

position-indicating radio beacons (EPIRBs) operating in the COSPAS-SARSAT system •MSC/Circ.1039, Guidelines for shore-based maintenance of satellite EPIRBs •MSC/Circ.1040, Guidelines on annual testing of 406 MHz satellite EPIRBs •Recommendation ITU-R.M.633-4 •Updated work plan for submission to NCSR 6 For emergency position-indicating radiobeacons operating on 406.0–406.1 MHz (406.0–406.1 MHz EPIRBs) that were authorized prior to April 15, 1992, and meet the requirements of § 80.1101, the manufacturer may attest by letter that the equipment (indicate FCC ID#) meets the requirements of § 80.1101 and request that it be denoted as ^{Hydrostatic release units. The Hydrostatic Release Unit (HRU) is designed and approved to automatically deploy a life raft or EPIRB in the event of a vessel sinking. HRUs operate between 1.5 and 4 metres of water depth, to release the securing mechanism for the life raft or EPIRB. AMSA inspectors often identify circumstances where HRUs are}

^{Check that the rear side of the mounting surface is clear and that the fixing screws will not penetrate through into any other objects. Offer the bracket into the chosen position and mark through the mounting slots using the bracket as a template. Drill four 3mm (1/8”) holes and securely screw the bracket in place.} EPIRB - Emergency Positioning Indicating Radio Beacon. EPIRB (Emergency Position Indicating Radio Beacons) and PLB (Personal Locator Beacons) are a fast effective way of distress alerting for any kind of vessel. A 406MHz beacon enables the SAR (Search and Rescue) agencies to quickly and accurately identify and locate a casualty so that they can

Remember, a SART is not an alternative to an EPIRB, they are designed to fulfill two completely different functions. All things being equal, the ideal situation of course is to have both. If you are just beginning the fitting out of your boat, the question may arise whether the purchase of an EPIRB or a SART is in your best interest.

results were obtained with a SART in a survival craft: – SART lying flat on the floor: range 1.8 nm – SART standing upright on the floor: range 2.5 nm – SART floating in the water: range 2.0 nm 3. Effects of survival craft on SART signal Tests have been made with a SART mounted on a survival craft to give a 1 m antenna height, in order to The SART is normally mounted on a short pole on the survival craft. It is a transponder and only transmits when interrogated by a radar signal. The SART works at X-band frequencies only. It is activated by a radar pulse from a vessel and transmits a series of 12 short radar pulses on the same frequency.
