Disconnecting 
batteries 

If the equipment was disconnected from the network 
supply  for  a  long  time,  the  battery  will  be  gradually 
discharged.  In  this  case  electrically  disconnect  the 
batteries  from  the  system.  This  can  be  done  in  two 
ways: 

-

 

by pressing “TEST ”+ “RESET ”at the same time 

-

 

by switching the micro switch in the left lower 
part  of  the  box  which  is  accessible  from  the 
bottom after partially ejecting the box (about 
5 cm ) from the 19 “frame.
