False alarms 

To prevent false alarms, it is important to be aware of how your beacon can 
be  activated.  An  ACR  406  MHz  EPIRB  can  be  activated  by  two  different 
methods. Whether you have a Category I or Category II, these methods are 
the same. 

// 

When  the  beacon  is  out  of  its  bracket  and  wet,  the  unit  will  start 
transmitting 

// 

When  the  switch  is  moved  to  the 

“ON”  position,  in  or  out  of  the 

bracket, the unit will start transmitting 

 

Precautions to prevent false alarms 

// 

Do  not  mount  or  transport  the  beacon  within  4.6  ft/1.4  m  of  a 
magnetic source. 

// 

Do not store the beacon outside of its bracket if it can get wet. 

// 

Do not mount the EPIRB backwards in its bracket (lanyard roll must 
face in). 

// 

Do  not clean  the  beacon  with  a  water  hose  and  brush  while  out  of 
its bracket. 

 

Reporting 

Should there  be, for any reason,  an  inadvertent activation or false alarm, it 

must

  be  reported  to  the  nearest  search  and  rescue  authorities.  The 

information that should be reported includes: 

// 

The EPIRB 15-digit Unique Identifier Number (UIN) 

// 

Time and date 

// 

Duration and cause of activation 

// 

Location of beacon at the time of activation
