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).

(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.

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

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.

2.3.2 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.

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.

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 V_RMS, 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.
