EPIRBEmergency Position Indicating Radio BeaconTwo basic typesCAT I – automatic releaseand activationCAT II – manual release
EPIRB – BracketsCAT ICAT II
Types of Brackets Category 1 (Float Free)– Hydrostatic Release between 1.5 – 4.0meters(4.9-13.1 ft.)– EPIRB is transmitting when it getsto the surfaceHydrostatic release needs replacement every two yearsfrom installation date or 4 years from manufacture.
CAT 2 BRACKETMust be manually removed from bracket.Once removed from bracket can be manually activated orautomatically by throwing in the water.

Testing Bracket MagnetA Compass providessimple detection onbracket magnet.
Activation Typical activation includes Auto – put in “Armed” or “Ready” position Manual - switch to “Manual” or “On”Has a barrier to keep from accidental manualactivation.3/5/201410
