Introduction
1.0 Introduction
MGC’s remote shared display is the RAXN-LCD. The RAXN-LCD provides a replica of the
main 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 41 frames made up of display adder modules and up to 7 RAXN-LCDs per
node, refer to figure below. The RAXN-LCD may be mounted in the BB-1000 (MMX-BB-1000)
Series backboxes, the BB-5008, BB-5014, BBX-FXMNS (MMX-BBX-FXMNS) and FX-LOC
(MMX-LOC) enclosures.

DIP Switch Settings
4.0 DIP Switch Settings
Each RAXN-LCD Shared Display Annunciator needs to be assigned a unique address via the
DIP switches of SW1.
The RAXN-LCD SW1 DIP switches are set by selecting the active ON. The addresses
available for the RAXN-LCD are 33 to 39, inclusive. Set the address as follows in the table
below:
RAXN-LCD Address SW1-1 SW1-2 SW1-3 SW1-4 SW1-5 SW1-6 SW1-7 SW1-8

DIP switch SW1 is
used to set the
address of the
RAXN-LCD
DIP switches are for assigning an address to the RAXN-LCD. Binary addresses 33 to 39 are
available with the least significant bit being switch SW1-1 on the left and the most significant
bit being SW1-6. The ON setting is active binary. DIP switches SW1-7 and SW1-8 are not
used.
For example, address 33 is set by pushing DIP switch SW1-6 and SW1-1 to the ON position
and all the other DIP switches to the OFF position.
Refer to Network Fire Alarm Manual as to whether addresses 37 to 39 are available.

The RS-485 wiring to the
RAXN-LCD Display Module
is recommended to be
twisted shielded pair as
shown in the diagram to the
right. The RS-485 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 RAXN-LCD Shared
Display has a 120 ohm end-
of-line resistor on its RS-485
output terminals. This
resistor is removed on all except the last wired annunciator.
24V DC Wiring
The 24 VDC field wiring needs to be of an appropriate gauge for the number of annunciators
and the total wiring run length. Refer to the Current Drain for Battery Calculations on page 8
to calculate the maximum current for all annunciators summed together.
!
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.

The RAXN-LCD may be utilized by itself in a remote location or within a larger enclosure
together with other display modules. It may also be used as part of a mass notification system.
