The Tron 40S MkII is buoyant and is designed to automatically release and activate in case of an emergency where the EPIRB and its bracket are submerged into the sea. The Tron 40S MkII can also be operated as a manual EPIRB.
Six different brackets are currently compatible with Tron 40S MkII. MB4 and MB5 are the manual brackets and FB4 and FBH4 is the automatic bracket. FB6/FB5 is an automatic bracket with cover. The automatic bracket is mounted in a free space outside where the beacon can be released automatically.
The purpose of the Tron 40S MkII 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 self-test on the transmitters and on the battery status. No emergency signal is transmitted during the self-test. The battery of the EPIRB will last for at least 48 hours from the activation of the EPIRB.
