1.0 Technical Information
1.1 General
The RAM-2944LCD Annunciator Driver is capable of controlling up to 576 LEDs, as 192 zones
of 3 LEDs each (Alarm, Supervisory, Trouble), for use with columnar or graphic annunciators.
Two optional LCD displays are available, an 80 character (4 x 20) display display and a larger
display twice that size. Both can be used to display text messages.
The RAM-2944LCD uses the NWM-2944-R Network Communications Board for network
interface. The RAM-2944LCD can use all variants of the NWM-2944-R board. The RAM-
2944LCD may also use the FM-2200-R1 Fiber Optic Modem for connecting a fiber network
between panels.
The RAM-2944LCD uses the AN4 program for connection to FX-2200 networks.
The LEDs are interfaced to the Annunciator Driver using the RAM-2944-24 Annunciator Strip,
the RAM-2944-8 Annunciator Strip or the AGD-2944-8 LED Driver.

Installation
2.0 Installation
2.1 Mounting
These mounting instructions apply only to annunciators that come complete with cabinet.
1. Choose a suitable location for mounting.
2. Mark placement of mounting screws using template. Make sure that the template is
level.
3. Drill holes, install plugs (if necessary) and top two screws.
4. Hang the cabinet on screws and pull down to ensure a snug fit. The cabinet should be
level.
5. Install bottom screw(s) and tighten all screws.
6. Connect network and power wiring. Operator key wiring and LED wiring, if any, is done
at the factory. Power can be taken from an external 24VDC source. An external source
must be UL/ULC listed for use with fire alarm systems.
2.2 Wiring
2.2.1 Power
The Annunciator panel requires 24 VDC for operation from a power limited source. This shall
be provided from either the AUX 1 or AUX 2 auxiliary power connections on the Fire Alarm
Control Panel. The 24 VDC is connected to the +24 terminal (positive) and the GND terminal
(negative). See Figure 1 for terminal locations.
Note: For use with FM-2200-R1 Fiber Optic Modem, power must be supplied by a
regulated, power-limited 24 VDC power supply that is UL-listed for Fire
Protective Signalling Service.
Note: Operator key and LED wiring is required only for units that do not come complete
in a cabinet.
Note: Annunciator must be powered from panel or from a regulated, power-limited
power supply listed for Fire Protective Signalling Service (or any other power
supply for which compatibility has been verified by UL).

Installation
2.2.2 Network to FX-2200
Network wiring for communications to the FX-2200 is
connected to the terminal pairs marked C1+/C1- and C2+/
C2- (see Figure 1). The wiring is not polarity sensitive.
COM1 (C1+/C1-) is connected to COM2 the next panel in the
network loop. Ensure that the Annunciator is programmed to
communicate with the next panel or that COM1 is disabled as
required in the downloaded database. COM2 (C2+/C2-) is
connected to the previous panel in the network loop.
2.2.3 Operator Keys
All operator keys are wired between an X and a Y terminal. A
key switch may be placed in series with the Y2 terminal to
make certain operator keys limited access (see Figure 2).
The figure is typical only; any, all or none of the operator keys
can have the key switch used.
2.2.4 LEDs
The RAM-2944-24 Annunciator Strip, RAM-2944-8
Annunciator Strip and the AGD-2944-8 LED Driver are
connected to the Annunciator by ribbon cables (see Figure
1). The eight connectors on the Annunciator are labelled P1 to P8. P1 is for zones 1 to 24, P2
Notes: If the annunciator is programmed for two port operation, both communications
ports must be connected even if there is only one other unit in the system.
If the annunciator is programmed for single port operation, only COM2 (C2+/C2)
is connected.
COM1 and COM2 are power-limited and supervised.
For information on connecting a fiber optic network, please refer to the Fiber
Optic Module’s Installation Manual.

for zones 25 to 48, etc. Each RAM-2944-8 and AGD-2944-8 controls 8 zones. Up to 3 RAM-
2944-8s or AGD-2944-8s can be chained together to provide up to 24 zones per chain. Each
RAM-2944-8 will require a jumper for addressing (see below). No jumpers are set on the
AGD-2944-8 for addressing purposes.
The AGD-2944-8 LED Driver has a 50 pin connector for connection to the LEDs. The LEDs
are wired to a 50 pin socket which the AGD-2944-8 plugs into. The pin-outs are shown in
Figure 3.
2.2.5 RAM-2944-8 Jumper Settings
The jumpers for setting the octet are located just below the ribbon cable connector (see Figure
4). There are three pairs of holes. Soldering a wire jumper across the required pair will set the
RAM-2944-8 to be the first, second or third octet. There is a trace on the board jumpering the
pair for the first octet. This will need to be cut if the board is for the second or third octet.
Attention: Do not use P11 for LEDs. This will cause damage to both the RAM-
2944LCD and the LED driver.

Operation
3.0 Operation
3.1 LEDs
There are 192 LED zones available on the Annunciator, each zone consisting of Alarm (red),
Supervisory (amber) and Trouble (yellow) LEDs. The LEDs will flash if a new condition is
received. If the buzzer is sounding, press Acknowledge to silence the buzzer. Press
Acknowledge (again) to latch the LEDs. Once the condition is restored, the LED can be
turned off by pressing Reset. If global commands are enabled, these operator keys will be
broadcast to the network, causing all units to respond to the operator keys. An asterisk will
appear at the end of the LCD display line showing the current time if any of the LEDs can be
reset. If the Alarm List is being displayed, the current time will not be displayed.
If the RAM-2944LCD has a memory or configuration error, the buzzer will sound every 2
seconds. This also occurs while loading a database.
If LEDs are programmed, the table below shows the meaning for each LED when flashing.
The Power On LED flashes when the annunciator first starts operating and stays steady after
the Acknowledge key is pressed.
If a common LED is programmed, it will show the sum of all the Zone LEDs that are on. The
common LED will also indicate troubles that are local to the Annunciator only. The Hot LEDs
have no effect on the common LED.
Lamp Test flashes the LEDs in sequence. Pressing Lamp Test repeatedly will cycle through:
alarm LEDs, supervisory LEDs, trouble LEDs, and Lamp Test off. The test will automatically
end if any new condition is received, or after 5 minutes. The lamp test cannot be performed if
AC power is off.
3.2 Buzzer
The buzzer gives audible indication of any conditions in the panel. It may sound in any of four
modes. Pressing Acknowledge will silence the buzzer. (Acknowledge will need to be pressed
again to latch flashing LEDs.)
The four buzzer modes are:
Steady: This indicates any new fire alarm conditions. This mode can be disabled in the
database.

Operation
Fast: This indicates any critical failures that must be attended to. These failures can include,
but are not limited to memory overflow, network reboot required, database mismatch, etc. The
pattern in 50ms on/off.
Medium: This indicates any new supervisory conditions. The pattern is 200ms on/off.
Slow: This indicates any new trouble conditions. The pattern in 500ms on/off. Through
programming, a new trouble condition can be made to not sound the buzzer again for a time
after it has been silenced. This time can be set from 15 to 255 seconds. By default, the
buzzer will sound for all new troubles.
3.3 Operator Keys
There are 16 operator key inputs. The operator keys can be programmed in the database to
be either local or global. If the operator keys are local, they affect the RAM-2944LCD
Annunciator only. If the operator keys are global, they will be broadcast over the network,
causing all units on the network to respond to the operator key. The operator keys are laid out
in a 4 by 4 matrix as follows:
If global commands are enabled, all operator keys that have global ability will be broadcast to
the network. All units on the network will respond as if the operator key was pressed at the
unit itself, except it will not beep. The annunciator will always send the global commands,
even when they are not valid at the Annunciator. The LCD back light will turn on if a operator
key is pressed. The back light will automatically turn off in 5 minutes if there is no activity.
3.4 Alarm List
The Alarm List contains all the current Alarms, Supervisory Conditions and Troubles. The
Alarm List will hold entries as requested by other panels in the network. The first/last entry of
highest priority will be shown, instead of the time display, if there are any entries in the Alarm
List. Alarms are the highest priority, Supervisory Conditions are the 2nd priority and Troubles
the 3rd priority, Monitor Conditions are 4th priority and Non-reporting signals are the lowest

There are two display modes of operation:
•First: Displays the first entry of highest priority and then each next entry as requested.
•Last: Displays the last entry of highest priority and then each previous entry as
requested.
There are two reset modes of operation:
•Automatic: Entries are removed from the Alarm List as soon as the condition restores.
•Manual: Entries that can be removed from the list have the condition code shown with
a "-" instead of a "+". Press Reset to remove these entries from the Alarm List.
The event screen of an entry shows one of two forms:
1. Line 1: time, sequence number, and Condition Code

Programming
4.0 Programming
4.1 General
The Annunciator Unit's service terminal is accessed through the 9-pin RS-232 serial port
located on the bottom of the RAM-2944LCD Driver Board. The programming cable uses pins
2, 3 and 5 straight through from DB9 male to DB9 female plugs. The serial port works at 9600
bps, 8 data bits, 1 stop bit and no parity.
When programming the Annunciator for the first time, the only item that MUST BE
PROGRAMMED from the service terminal is the Annunciator's network ID (default value is
101). The network ID is shown on the top line of every screen to identify the panel being
serviced. To change the panel's ID, first go to screen 16 by entering the command 16<Tab>.
Set Privilege Level 2 by entering (code)<Ctrl-V> where code is the Level 2 passcode (default
2222). To set the ID enter the command idN, where id is the network ID of the Annunciator, a
number between 1 and 254.
All other required programming is taken from the database generated by the Modul-R Human
Interface program (MHI). Downloading the database into the RAM-2944LCD annunciator is
automatically handled by MHI. See the Modul-R Human Interface Database Editor for details
on downloading databases.
Non-required programming controlling the operation of the Alarm List and the communications
parameters of the primary network port (if used) are set using the service terminal.
4.2 Service Terminal Screens
All screens have a common status line showing the current time, a diagnostic number, the
annunciator's ID number and the screen number and name. Screens will also list keyboard
commands related to the screen's information. Some commands require a privilege level set
before they can be used.
The following screens are available, those that are most useful for the installer are marked
