Adherence to the following will aid in problem-free  
installation with long-term reliability:  
Installation Precautions  
WARNING - Several different sources of power can be  
connected to the fire alarm control panel. Disconnect all  
sources of power before servicing. Control unit and  
associated equipment may be damaged by removing  
and/or inserting cards, modules, or interconnecting  
cables while the unit is energized. Do not attempt to  
install, service, or operate this unit until this manual is  
read and understood.  
Like all solid state electronic devices, this system may  
operate erratically or can be damaged when subjected  
to lightning-induced transients. Although no system is  
completely immune from lightning transients and inter-  
ferences, proper grounding will reduce susceptibility.  
Overhead or outside aerial wiring is not recommended,  
due to an increased susceptibility to nearby lightning  
strikes. Consult with the Technical Services Department  
if any problems are anticipated or encountered.  
CAUTION - System Reacceptance Test after Software  
Changes. To ensure proper system operation, this  
product must be tested in accordance with NFPA 72  
Chapter 7 after any programming operation or change in  
site-specific software. Reacceptance testing is required  
after any change, addition or deletion of system compo-  
nents, or after any modification, repair or adjustment to  
system hardware or wiring.  
Disconnect AC power and batteries prior to removing  
or inserting circuit boards. Failure to do so can damage  
circuits.  
Remove all electronic assemblies prior to any drilling,  
filing, reaming, or punching of the enclosure. When  
possible, make all cable entries from the sides or rear.  
Before making modifications, verify that they will not  
interfere with battery, transformer, and printed circuit  
board location.  
All components, circuits, system operations, or software  
functions known to be affected by a change must be  
100% tested. In addition, to ensure that other operations  
are not inadvertently affected, at least 10% of initiating  
devices that are not directly affected by the change, up  
to a maximum of 50 devices, must also be tested and  
proper system operation verified.  
Do not tighten screw terminals more than 9 in-lbs.  
Over-tightening may damage threads, resulting in  
reduced terminal contact pressure and difficulty with  
screw terminal removal.  
Though designed to last many years, system compo-  
nents can fail at any time. This system contains static-  
sensitive components. Always ground yourself with a  
proper wrist strap before handling any circuits so that  
static charges are removed from the body. Use static-  
suppressive packaging to protect electronic assemblies  
removed from the unit.  
This system meets NFPA requirements for operation  
at 0-49° C/32-120° F and at a relative humidity of 85%  
RH (non-condensing) at 30°C/86° F. However, the  
useful life of the system's standby batteries and the  
electronic components may be adversely affected by  
extreme temperature ranges and humidity. Therefore,  
it is recommended that this system and all peripherals  
be installed in an environment with a nominal room  
temperature of 15-27° C/60-80° F.  
Follow the instructions in the installation, operating,  
and programming manuals. These instructions must  
be followed to avoid damage to the control panel and  
associated equipment. FACP operation and reliability  
depend upon proper installation by authorized personnel.  
Verify that wire sizes are adequate for all initiating and  
indicating device loops. Most devices cannot tolerate  
more than a 10% I.R. drop from the specified device  
voltage.

ADT-LCD40  
ADT-LCD40L  
Note: Only Model ADT-LCD40L is listed for use in Canada.  
The ADT-LCD40 Series Annunciators are compact, attractive,  
40-character, backlit LCD fire annunciators designed for use with the  
Unimode 200 Addressable Fire Alarm Control Panel. The  
ADT-LCD40L operates the same as the ADT-LCD40, except it does not  
have function switches or a key-switch. It should be noted that the  
ADT-LCD40 Series Annunciator displays will mimic the LCD display  
located on the Unimode 200 main circuit board.  
If software with Part Number #UNIMODE200V3.0 is installed in the  
ADT Unimode 200, the ADT-LCD40 Series Annunciator must have soft-  
ware with a Part Number of 73879 to operate with the control panel. If  
software with a Part Number of #UNIMODE200V4.0 or higher is  
installed in the Unimode 200, the ADT-LCD40 Series Annunciator must  
have software with a Part Number of #LCD40V2.0 or higher to operate  
with the control panel.  
The ADT-LCD40 Series is capable of displaying English-language text  
of system point status including device type, independent point alarm,  
trouble or supervisory, zone and custom alpha labels programmed into  
the control panel. The ADT-LCD40 Series also provide system status  
LEDs to display Power, Alarm, Trouble and Supervisory conditions.  
The ADT-LCD40 is capable of performing system acknowledge,  
silence, drill and reset remotely while the ADT-LCD40L does not have  
these features.  
Communication between the control panel and the ADT-LCD40 Series  
is accomplished over a two-wire serial interface employing the EIA-485  
communication standard. Up to 32 annunciators may be connected to  
the two-wire EIA-485 circuit. The annunciators may be powered from  
the host FACP or remote UL listed, filtered, power supplies.

SW1 DIP Switch Settings  
1.3  
SW1 DIP Switch Settings  
The Up position on DIP switch SW1 is the Off state. Refer to “DIP  
Switch Settings Example” on page 11, for an explanation of DIP switch  
positions. SW1 switch settings follow:  
1 - On (Down) = Receive/Transmit, Off (up) = Receive Only.  
Set switch 1 to Off (Up) position for all ADT-LCD40 Series Annun-  
ciators except the last (or only) annunciator on the EIA-485 loop.  
Set switch to On (Down) position for the last or only annunciator on  
the EIA-485 loop to allow transmission of a supervision signal (and  
function switch depressions on the ADT-LCD40) back to the FACP.  
The last or only annunciator must be set for Receive/Transmit  
(switch 1 in the Down position).  
A break (open circuit) in the power or EIA-485 connections creates  
an ADT-LCD40 Series Annunciator fault at the Unimode 200 panel.  
All annunciators before the break will continue to display informa-  
tion (but the function switches on the ADT-LCD40 will no longer  
operate).  
2 - ADT-LCD40 Only (not used on the ADT-LCD40L)  
On (Down) = Key-switch enabled, Off (Up) = Key-switch disabled.  
Switch 2 set to the On (Down) position enables key-switch  
operation. The key-switch may now be used to enable the  
ADT-LCD40 membrane switches, allowing remote switch func-  
tions, or lockout the switches, preventing remote switch functions  
Switch 2 set to the Off (Up) position disables the key-switch  
operation. Refer to “Switch Functions for ADT-LCD40 Only” on  
page 14, for key-switch function description.  
3 - On (Down) = Piezo sounder enabled, Off (Up) = Piezo sounder  
disabled.  
CAUTION: Piezo sounder must not be disabled without prior  
approval of the Local Authority Having Jurisdiction (LAHJ).

from FACP to annunciator and back to FACP for supervision  
(3,000 feet [900 m] maximum to last ADT-LCD40). Circuit is  
power-limited.  
2. Up to 32 ADT-LCD40 Series Annunciators may be used on the  
EIA-485 circuit. The Unimode 200 can power a maximum of  
five annunciators. If additional annunciators are connected, the  
FCPS-24F may be used to supply additional power. Power  
supplies used for this purpose must have their negative terminals  
commoned together.  
3. Between each ADT-LCD40 Series annunciator are four wires - a  
twisted shielded pair for data communications and a pair for 24  
VDC power. The return circuit only requires two wires for data  
communication supervision, wired from the last or only annunci-  
ator on the line.

Operation  
Display Patterns  
Section 2:  
Operation  
2.1  
Display Patterns  
The ADT-LCD40 Series Annunciators directly display (mimic) the  
information on the Unimode 200 main circuit board LCD display with  
the following exceptions:  
• Upon Power-up, the ADT-LCD40 Series may display the  
following message until a valid message is received from the  
Unimode 200  
SYSTEM POWER UP  
WAITING FOR THE FACP  
• If an ADT-LCD40 Series Annunciator fails to receive communi-  
cations from the panel for a period of over 30 seconds, it will  
activate its local sounder (if so programmed) and display the  
following message:  
COMMUNICATIONS FAIL  
• When placing the host Unimode 200 into some aspects of the  
Programming Mode, the annunciator will display the following  
message:  
PROGRAMMING THE  
UNIMODE-200 PANEL  
The message shown above will appear at the Level One passcode for  
(1) Autoprogram, (2) Point Edit, (3) System Edit, (4) Passcode Entry  
and (5) Load. The same message will also appear at the Level Two  
passcode for (1) Disable, (2) Clear History and (4) Time.

Switch Functions for ADT-LCD40 Only  
2.2  
Switch Functions for ADT-LCD40 Only  
2.2.1 Key-switch  
Key-switch (shown in Off position)  
The key-switch is used to enable  
and disable the operation of the  
function switches if switch 2 on  
DIP switch SW1 has been placed  
to the On (Down) position.  
ATOR  
To enable the Acknowledge,  
Silence, Drill and Reset function  
switches, insert a standard ADT  
key into the key-switch located at  
the top right corner of the  
Reset  
ADT-LCD40. Make certain the  
key is inserted completely before  
attempting to turn it. Turn the key  
clockwise until it stops. Leave the key inserted while pressing the  
function switches. When finished with the function switches, turn  
key-switch counterclockwise to disable function switches.  
Note that the key-switch should normally be in the disabled position  
(fully counterclockwise), with the key removed and access to the key  
restricted to authorized personnel only. Do not leave the key  
unattended in the ADT-LCD40.  
2.2.2 Acknowledge  
When the Acknowledge switch is pressed and released, the  
ADT-LCD40 sends an Acknowledge command to the control panel.  
Pressing the Acknowledge switch silences the local piezo sounder,  
the sounders located in all other system annunciators and the  
sounder located on the Fire Alarm Control Panel's main circuit  
board. It will also change all flashing system LEDs to steady on.  
Only one press is necessary regardless of the number of new alarms,  
troubles or supervisory signals.  
An acknowledge message is also sent to the printer and the history  
files in the Unimode 200. Multiple active events (alarms, troubles,  
supervisories) are scrolled on the display at a one second rate, but  
may be held for sequential display by pressing and holding the  
Acknowledge switch.  
When more than one event exists, the first press of the Acknowledge  
switch silences system piezo sounders and changes all flashing  
Document 50520 Rev D 7/25/00 P/N 50520:D  
14  
 
Operation  
Switch Functions for ADT-LCD40 Only  
LEDs to steady on. The second press of the switch stops the scroll-  
ing and holds the event on the display for one minute. Subsequent  
pressing of the switch 'steps' through each active event.  
2.2.3 Silence  
When the Silence switch is pressed and released, the ADT-LCD40  
sends a signal silence command to the control panel. The Silence  
switch performs the same functions as the Acknowledge switch. In  
addition, if an alarm exists, it turns off all silenceable NACs and  
causes the FACP Alarm Silence LED to turn on while the  
ADT-LCD40 will display a 'silenced' message. It also sends an  
'Alarm Silenced' message to the printer and the history file within the  
Unimode 200. A subsequent new alarm will resound the appropriate  
NACs (Notification Appliance Circuits) and local sounders.  
2.2.4 Drill: Hold 2 Sec.  
When the Drill switch is pressed and held for at least two seconds  
(time required to prevent accidental activations), the ADT-LCD40  
will transmit a drill command to the control panel. This command  
causes the FACP to turn on both main panel NAC outputs and all  
silenceable circuits (all C304 modules/NACs that are programmed  
silenceable). In the event that the system was previously silenced,  
the drill command will also turn off the Alarm Silence LED. The  
'Manual Evacuate' message is shown on the ADT-LCD40 display.  
The same message is sent to the FACP display, printer and history  
files. The Silence switch operates on silenceable NAC outputs only.  
2.2.5 Reset  
When the System Reset switch is pressed and released, the  
ADT-LCD40 sends a Reset command to the control panel. This will  
turn off all C304 modules and Notification Appliance Circuits, tem-  
porarily turns off resettable power to 4-wire detectors, causes a 'Sys-  
tem All Normal' message to be displayed on the ADT-LCD40 and  
sends a 'System Reset' message to the FACP display, printer and Uni-  
mode 200 history files. It also turns on all system LEDs, piezo  
sounders and LCD display segments as long as the Reset switch is  
held (lamp test). Any alarm or trouble that exists after a Reset will  
resound the system.

2.3.1 Power  
This is a green LED which illuminates if AC power is applied to the  
host FACP. The green LED will turn off if AC power to the host  
FACP is lost.  
2.3.2 Fire Alarm  
This is a red LED that flashes when one or more fire alarms occur. It  
illuminates steadily when an Acknowledge or Silence switch is  
pressed. The Alarm LED turns off when the Reset switch is pressed.  
2.3.3 Supervisory  
This is a yellow LED that flashes when one or more supervisory  
conditions occur, such as a sprinkler valve tamper condition. It  
illuminates steadily when an Acknowledge or Silence switch is  
pressed. It turns off when the Reset switch is pressed.  
2.3.4 Trouble  
This is a yellow LED that flashes when one or more trouble condi-  
tions occur. It stays on steady when an Acknowledge or Silence  
switch is pressed. The LED turns off when all trouble conditions are  
cleared. This LED will also illuminate if the microprocessor watch-  
dog circuit within the ADT-LCD40 Series is activated.

Mounting  
ADT-LCD40 Series Preparation  
Section 3:  
Mounting  
3.1  
ADT-LCD40 Series Preparation  
The ADT-LCD40 Series Annunciators can be surface mounted in a  
three-gang electrical box such as the P/N SBB-3 (2.75" depth) or semi-  
flush mounted in a three-gang electrical box, P/N 10103 or equivalent,  
with a minimum depth of 2 3/16". The ADT-LCD40 Series Annuncia-  
tors cannot be mounted in three gangable electrical switch boxes con-  
nected together. Select and remove the appropriate knockout(s), pull the  
necessary wires through the knockouts and mount the three-gang box in  
or on the wall depending on the type of installation desired. Be certain  
that power is not applied to the wiring during the installation procedure.  
Note: To ensure static protection, all enclosures, including the  
ADT-LCD40 Series electrical box, must be connected to earth ground!  
Never use the shield for grounding purposes.  
To mount the ADT-LCD40 Series Annunciators in an electrical box, the  
trim ring must first be removed. The trim ring is held in place by two  
screws inserted through the top and bottom edge as illustrated in Figure  
3-1. Removal of the trim ring will expose a metal flange with mounting  
holes. Refer to “Hardware and Backboxes” on page 18.

ADT-LCD40 Series Electrical Connections  
Power Connection  
Section 4:  
ADT-LCD40 Series Electrical  
Connections  
The ADT-LCD40 Series Annunciators can be powered by the Unimode  
200 24VDC nominal power or from a remote UL listed, filtered power  
supply such as the FCPS-24F. The power run to the annunciator must  
be power-limited but need not contain a power supervision relay since  
loss of power is inherently supervised through loss of communication  
with the annunciator. Maximum ADT-LCD40 Series current draw from  
the power supply (under alarm condition) is 66 mA. Maximum current  
draw from the control panel's secondary power source (batteries) under  
loss of AC power is 28 mA, since the LCD backlight is turned off during  
AC loss. Backlighting is turned back on during AC loss only for alarm  
conditions in the system.

EIA-485 Shield Termination  
EIA-485 Shield Not in Conduit  
Section 5:  
EIA-485 Shield Termination  
The EIA-485 circuit must be wired using a twisted, shielded pair cable  
with a characteristic impedance of 120 ohms (+/- 20%). Do not run  
cable adjacent to or in the same conduit as 120 VAC service, noisy  
electrical circuits that are powering mechanical bells or horns, audio  
circuits above 25 VRMS, motor control circuits or SCR power circuits.  
Note: To ensure static (ESD - electrostatic discharge) protection, all  
enclosures, including the ADT-LCD40 Series electrical box, must be  
connected to earth ground! Never use the EIA-485 shield for this  
purpose. The EIA-485 shield is for radiated noise emission protection  
(RFI, EMI). Refer to the following figures for details on EIA-485 shield  
termination.  
5.1  
EIA-485 Shield Not in Conduit  
The EIA-485 line allows the FACP to communicate with the  
ADT-LCD40 Series Annunciators. The shield for the EIA-485 line  
must be connected to earth ground at the FACP but must be left floating  
(no connection) at the annunciator if it is the first or only device on the  
EIA-485 line. If a second annunciator is connected, the shield leaving  
the first annunciator must be left floating. The shield entering the sec-  
ond annunciator must be connected to the three-gang box or Earth  
Ground terminal (P2-7) on the second annunciator. If additional annun-  
ciators are connected, the shield leaving each enclosure must be left  
floating and the shield entering each must be connected to the three-  
gang box or the Earth Ground terminal (P2-7) on the annunciator.

5.2  
EIA-485 Shield in Full Conduit  
The EIA-485 line allows the FACP to communicate with the  
ADT-LCD40 Series Annunciators. The shield for the EIA-485 line  
must be connected to earth ground at the FACP (both exiting and  
entering the FACP) but must be left floating (no connection) at the  
annunciator if it is the first or only device on the EIA-485 line. If a  
second annunciator is connected, the shield leaving the first annunciator  
must be floating. The shield entering the second annunciator must be  
connected to the Earth Ground terminal (P2-7) on the second annuncia-  
tor. If additional annunciators are connected, the shield leaving each  
annunciator must be left floating and the shield entering the following  
unit must be connected to the Earth Ground terminal (P2-7) on the  
annunciator.  
Caution! Do not allow the floating (no connection) end of the shield to  
contact the conduit. The floating end should be insulated from earth  
ground.

0=CLR 1=AUTO 2=POINT  
3=SYS 4=PWORD 5=LOAD  
Press '3' to enter System Edit. The system edit screen may appear as  
shown (note that previous programming may have altered some N or No  
designations to Y or Yes):  
V=N I=N A=N P=N C=N  
A/U=N L/P=N S=4 R=4  
Use the left and right arrow keys to move to the L/P option. Once at the  
L/P option, to enable the ADT-LCD40 Series Annunciator option, use  
the up and down arrow keys to scroll to the L (for ADT-LCD40 Series  
Annunciator) choice. The ADT-LCD40 Series can now communicate
