Remove the plug-in terminal blocks from the ADT-LCD40(L) circuit 
board.  Connect the EIA-485 and power wiring into the terminal block 
positions illustrated in Figure 1-1 on page 8, Figure 4-1 on page 21 and 
Figure 4-2 on page 22.  Plug the terminal blocks back into the P1 and P2 
connectors on the back of the annunciator.  Set DIP switch SW1 for the 
desired options (refer to Figure 1-2 on page 9).

Carefully insert the ADT-LCD40(L) into the three-gang electrical box 
and attach it using the four mounting holes on the ADT-LCD40(L) 
flange and the four screws provided for this purpose.  Replace the trim 
ring and secure with the two screws which were previously removed.  
Adjust the plastic trim ring to the surface of the wall before tightening 
the screws.  Do not overtighten.
