LCD-40 Series Annunciator Wiring
Appendix C
The following drawing illustrates the wiring of two LCD-40 Series Remote Annunciators to an MS-9200 FACP. A
maximum of 32 LCD-40 Series annunciators may be connected to a single control panel. The EIA-485 wiring must
pass through a ferrite core (P/N FBD-1) in each LCD-40 Series. The illustration shows power supplied to the annun-
ciators by the MS-9200. For system applications requiring greater than the 300 mA of nonresettable power the
MS-9200 can supply or for remote locations, use the Fire•Lite FCPS-24FE Field Charger Power Supply.
The DIM-485 interface module is required when using the LCD-40 Series. Insert the plastic standoff, supplied with
the DIM-485, into the hole located near the J11 connector on the top right side of the MS-9200 main circuit board.
Note that older MS-9200 circuit boards do not have a hole near J11, thus preventing the insertion of the standoff.
Align the connector on the DIM-485 board with J11 on the MS-9200 main circuit board and align the hole on the
DIM-485 with the standoff inserted into the main circuit board. Carefully seat the DIM-485 connector on the main
circuit board J11 connector and press to seat the DIM-485 on the standoff.

Notes:
1) The table above shows terminal to terminal wiring between the
DIM-485 and one LCD-40 Series Annunciator
2) If more than one LCD-40 Series is installed, the wiring to the
DIM-485 In (+) Terminal 2 and In (-) Terminal 4 will be from
the Out terminals of the last installed LCD-40 Series
3) The LCD-40 Series must have the two supplied R120 (120
ohm) resistors installed across the In Terminals 2 & 4 and Out
Terminals 1 & 3. These resistors are required for impedance
matching
4) Refer to the LCD-40 Series Technical Manual Document
#50327 for detailed wiring information.
