If  the  Sentinel  detects  any  voltages  on  the  EDM  inputs  and  the  system  has  not  been 
configured for EDM, it will display the message 

EDM wiring does not match EDM option - CHECK 

EDM  MENU  OPTION. 

This  may  occur  if  the  User  Interface  Panel  has  been  replaced  or 

upgraded without the option being configured correctly.  

If either of these conditions occur please contact your local service representative.
