LCD-40 Series Annunciator Wiring
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-24F/E Field Charger Power Supply.
The LCD-40 Series Remote Annunciators wire directly to TB7 on the MS-9200 main circuit board. Switch SW3
must be set to the ‘down’ position (EIA-485 Terminal Mode) to configure TB7 for Terminal Mode annunciator oper-
ation. Note that older versions of the MS-9200 main circuit board do not have a TB7 connector. The DIM-485 inter-
face module is required for this board. 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
MS-9200 and one LCD-40 Series Annunciator
2) If more than one LCD-40 Series is installed, the wiring to the
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.
