1.0 Introduction
Mircom's FX-2000's remote shared display is the RAX-LCD. The RAX-LCD shared display
provides an exact replica (less 16 zone LEDs) of the main FX-2000 Fire Alarm Panel display
at a remote location. It is equipped with a large 4 line x 20 character back-lit alphanumeric
LCD display that uses a simple menu system complete with a directional keypad and switches
for Enter, Menu Cancel and Info. The display expands with up to a total of four RAX-
1048TZDS Adder Annunciator or six IPS-2424DS Programmable Input Switches Modules.
There are five types of enclosure available: the BB-1001D/R, BB-1002D/R, BB-1003D/R, BB-
1008D/R, and BB-1012D/R which can take 1,2,3,8,12 chassis respectively. It may also be
mounted in the BB-5008 and the BB-5014.

3.0 Wiring Instructions
The RS-485 wiring to the RAX-
LCD Display Module is
recommended to be twisted
shielded pair as shown in the
diagram to the right. The wire
gauge may be:
• 22 AWG up to 2000 ft.
• 20 AWG up to 4000 ft.
The RS-485 wiring from the
fire alarm control panel to
the annunciator(s) must be
point-to-point from the fire
alarm panel to the first
annunciator, then to the next
annunciator, and so on. No
star wiring or T-tapping is
allowed. Each RAX-LCD
Shared Display has a 120
ohm end-of-line resistor on
its RS-485 output terminals.
This is removed on all
except the last wired
module.
The 24 VDC field wiring needs to be of an appropriate gauge for the number of annunciators
and the total wiring run length. Use the Current Drain for Battery Calculations on page 8 to
calculate the maximum current for all annunciators summed together.

4.0 DIP Switch Settings
Each RAX-LCD Shared Display Annunciator needs to be assigned a unique address via the
switch SW1. The RAX-LCD DIP switches are set as:
The OFF setting is active. The addresses available for the RAX-LCD are 33 to 63. Set the
address as follows in the table below:
Note: All circuits are power limited and must use type FPL, FPLR, or FPLP power
limited cable.
Attention: Accidentally connecting any of the 24 VDC wires to the RS-485 wiring
will result in damage to the annunciator and/or to the fire alarm control
panel to which it is connected.

DIP switches are for assigning an address to the RAX-LCD.
Binary addresses 33 to 63 are available with the least
significant bit being switch SW-1 and the most significant bit
being SW-6. The OFF setting is active binary. DIP switches
SW1-7 and SW1-8 are not used. For example, address 33 is
set by setting SW1-6 and SW1-1 OFF and all the other DIP
switches are ON.
SW1-6 = Address A5(OFF)
SW1-7 = not used
SW1-8 =
Put in “OFF” position
for firmware restore
during power up. At
all other times put in
“ON” state.
