1.1 TRON 40VDR
The Tron 40VDR is buoyant and have water activated contacts which will start
DISTRESS transmission if deployed into water. Tron 40VDR are currently avail-
able with one float free bracket. The bracket prevents DISTRESS transmission if
water spray are applied to the EPIRB.
The Float free bracket, FB-40 is a covered bracket with an hydrostatic release
unit (HRU) which will release the Tron 40VDR if the bracket is submerged to a
depth of 2-4 meters if the ship are about to sink.
The purpose of the Tron 40VDR is to give a primary alarm to the search and
rescue authorities. The EPIRB gives an immediate alarm when activated, trans-
mitting 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 re-
sponsible. 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 168 hours from activation of the
EPIRB.
