Standard Components
A standard four zone LW-401 has one
module—the main board. An expander
board is added to provide four additional
zones, when needed.
MAIN BOARD
The Main board of the LW-401 contains the
intelligence for the system and performs all
of the input/output processing as listed
below:
• Two supervised Notification Appliance
Circuits provide 24 VDC at 1.5 amps.
Each circuit operates Class B (Style Y)
and can be independently programmed
to operate a number of different ways
(Non-Coded, March Time, Temporal, or
Simple Zone Code).
• Two Form C relays rated at 30 VDC at
1 amp resistive, 30 VAC at 500mA
resistive. These relays are for Alarm and
Trouble operation.
• A dual mode battery charger that
provides float and constant current
modes of charging sealed lead acid
batteries (15 Amp-Hour maximum).
• Nonvolatile storage of system configu-
ration so that configuration remains
intact during loss of system power.
• Four supervised power limiting
Initiating Device Circuits. Each circuit
operates Class B (Style B) and can be
independently programmed to operate
as an Automatic Alarm input, a Verified
Alarm input, a Supervisory input, or a
Generic input. Each initiating device
circuit can use an unlimited number of
manual shorting-type devices.
• CPU Fail LED.
DISPLAY
The LW-401 display, shown in Figure 2,
provides the user with the necessary interface to operate the fire detection system in
Normal, Test, and Program modes.

FRONT PANEL FUNCTIONS
The front panel of the LW-401 is comprised
of a seven segment display, function keys,
and LEDs. Their functions are described
below (Refer to Figure 2):
The LEDs
The green Power LED remains on steady when
AC power is connected and pulses when the unit
is operating from batteries.
The red Alarm LED pulses when an alarm is
detected until it is acknowledged. Then it remains
on steady until the alarm condition is reset.
The yellow Supervisory LED pulses when a
supervisory condition is detected until it is acknowledged. Then it remains on steady until the
supervisory condition is reset. Note that the
pulsing rates of the trouble and supervisory
conditions are different.
The yellow Trouble LED pulses when a trouble
condition is detected until it is acknowledged.
Then it remains on steady until the trouble
condition is reset. Note that the pulsing rates of
the trouble and supervisory conditions are
different.
The yellow Bypass/Alarm Silence LED is on
steady when a zone in the system is bypassed
and it pulses when a notification circuit is silenced. When an initiating device zone is bypassed, the appropriate yellow zone trouble LED
is on.
The Test/Program LED is on steady when the
Test mode is selected and it pulses when the
Program mode is selected.
The Sounder
CONDITION RATE OF PULSATION
SYSTEM ALARM Sounds steady
TROUBLE Pulses at 50% duty cycle
SUPERVISORY Pulses at 25% duty cycle

The Function Keys
The ACK key is used to acknowledge alarms,
troubles, and supervisory conditions. In general
the LEDs change from pulsing to steady to
indicate that the condition was acknowledged.
The SILENCE key silences the notification
appliance circuits that are configured as
silenceable. Pressing the SILENCE key a
second time causes the NACs to re-sound.
The RESET key resets the LW-401 and all of
the smoke detectors.
The DRILL key activates all of the notification
appliance circuits.
The yellow zone status LEDs indicate
a trouble or supervisory condition existing on a
particular input. Pulsing indicates the condition
was not acknowledged; on steady indicates it
was acknowledged.
The seven segment display indicates the
various system troubles and the programming and
test modes. The numbers and symbols that appear
on this display are described in the following chart.
The red zone status LEDs provide an
indication of the status of a particular zone.
Pulsing indicates an alarm condition in that
zone. When the alarm is acknowledged, the
LED remains on steady until the panel is reset.

OPERATING MODES
LW-401 Operation, Installation, and Maintenance ManualLW-401
The LW-401 annunciates the following
modes of operation:
• Alarm
• Supervisory
• Trouble
• Normal
• Program/Test
Alarm
The LW-401 Display board lights the
appropriate red alarm LED and the general
ALARM LED to indicate to the user that an
Alarm condition exists on an initiating device
circuit (IDC).
Supervisory
A Supervisory alarm condition is indicated on
the LW-401 by the SUPERVISORY LED
flashing along with the appropriate yellow
zone LED.
Zone Trouble
A Trouble condition is displayed by a
flashing TROUBLE LED along with the
appropriate yellow zone LEDs.
For a further description of the system fault
codes, see System Fault Troubleshooting
(Table 3, page 25).
Normal
The Normal Mode is the absence of any
alarm, supervisory, or trouble condition. The
POWER LED is lit in Normal mode when the
system has AC power. The Alarm, Trouble,
Supervisory, Bypass, and Zone status
LEDs are off, and the internal sounder is off.
Program/Test
The Program/Test Mode is used for system
configuration, test, and maintenance func-
When the LW-401 is in Program
tions.
Mode, it does not indicate alarm or supervisory conditions.
The System resets to normal mode after 2
minutes of front panel inactivity. When the
LW-401 is in the One Person System Test
Mode, it automatically returns to normal
mode after 20 minutes of inactivity.
Responding to a Fire Alarm
System Trouble (Fault) Codes
A number is displayed in the seven segment
display to indicate System Trouble (Fault)
Codes. They are:
Code 1: AC Power Fail/Brownout
Code 2: Notification Appliance Circuit 1
Code 3: Notification Appliance Circuit 2
Code 4: Ground Fault
Code 5: Municipal Tie Fault
Code 6: Battery Fault
Code 7: System Configuration Fault
Code 8: Auxiliary Port Fault
Code 9: Output Bypassed
Code 0: Hardware Failure
How the System Annunciates Fire Alarms
When a fire is detected on one of the initiating device circuits (IDCs), the LW-401
causes the System ALARM LED and the
appropriate Zone ALARM LED on the front
panel to flash and the system’s internal
audible to sound.
NOTE: Follow the response plan approved
by the local authority having
jurisdiction.

To Acknowledge Alarms
1. Unlock and open the door.
2. Press ACK to acknowledge (Block
Acknowledge) all alarms and other
conditions. The system ALARM and the
Zone ALARM LEDs on the front panel
stop flashing and remain on. The
system’s internal audible silences.
To Silence The Notification Appliance
Circuits
Press SILENCE after all alarms are acknowledged. The BYPASS LED on the front panel
flashes. The following four conditions are
checked before the Notification Appliance
Circuit(s) can be silenced:
1. If either NAC is programmed as NON-
SILENCEABLE, it will not silence.
2. If the NAC inhibit timer has been programmed (see
Set System Timing
on
page 13), the NAC will not silence until
the inhibit time delay has expired (6
seconds to 5 minutes.)
3. If either NAC is programmed for temporal
coding, it will complete sending out
the entire current temporal round before
silencing.
4. If either NAC is programmed for ZONE
CODING, all coded rounds for each
zone in alarm must be sent out before
the NAC will silence.
Once the NACs have silenced, pressing the
SILENCE a second time causes the Notification Appliance Circuits to re-sound, and the
BYPASS LED to turn off.
Responding to a Supervisory
Condition
How the System Annunciates
Supervisories
When a supervisory condition is detected, the
system causes the SUPERVISORY LED and
one of the yellow Zone TROUBLE LEDs on
the front panel to flash and the system’s
internal audible to sound.
To Acknowledge Supervisories
1. Unlock and open the door.
2. Press ACK to acknowledge (Block
Acknowledge) all supervisory and other
conditions. The system SUPERVISORY
and the Zone TROUBLE LEDs on the
front panel stop flashing and remain on
and the system’s internal audible silences.
To Reset
Press RESET. (The system will not reset
until all alarms, supervisories, and troubles
are acknowledged and all conditions are
returned to normal.)
Responding to a Trouble Condition
How the System Annunciates Troubles
When a trouble is detected, the system
causes the TROUBLE LED and the appropriate yellow Zone TROUBLE LEDs on the
front panel to flash and the system’s internal
audible to sound. Troubles will clear prior to

System Features
In addition to the standard modes of operation for reporting system conditions, the
LW-401 has user-programmable features
that are described below. Each topic identifies the Program Level used to select these
features. Refer to the Programming section
of this manual for instructions on how to
activate these features in your LW-401
System.
Initiating Device Circuit (Zone) Types
(Program Level 3)
The LW-401 has the following 4 zone types.
• General Alarm
• Alarm Verified Zones
• Supervisory Zones
• Generic Zones
General Alarm is the default setting for all
zones. Alarm Verified Zone and Generic
Zone operation are described below.
• Shorting-type input devices and smoke
detectors are compatible with all zone
types.
• Manual fire alarm stations and smoke
detectors can be mixed on zones where
local codes allow.
• On verified zones, the manual station
reports alarms when activated, without
delay.
Alarm Verification
The Alarm Verification Feature provides the
LW-401 with a way to verify an alarm from
area-type smoke detectors. This feature can
be used to reduce incidences of false
alarms.
A detector supervised with Alarm Verification
is turned off by the System immediately after
it reaches an alarm threshold. The trouble
LED for that detector's zone turns on. The
detector is verified for a length of time which
must not exceed 60 seconds. After power is
restored to the device, and for the next 60
seconds, if the detector once again reaches
the alarm threshold the system will report an
alarm condition. If after 60 seconds the
detector has not alarmed, any detector which
again reaches the alarm threshold will restart
the verification cycle. See Figure 7, page 12,
for a graphic illustration of the Alarm Verification Time cycle.
CAUTION:
Use only detectors which are subjected to
air velocities of less than 100 feet per
minute with Alarm Verification. Under dynamic air velocity conditions, smoke may
be swept from a smoke detector after the
initial alarm. That may cause a long delay
before verification. Do not select Alarm
Verification for such applications.
11
Page 15
LW-401
Operation, Installation, and Maintenance Manual
Figure 7
Line Graph of Alarm Verification
3. March Time Code
4. Simple Zone Code
A steady tone is the default choice for each
circuit. A nonsilenceable NAC has a steady
tone. Temporal Code is as defined by NFPA
72. (Simple Zone Code is explained below.)
Please note that while it is possible to pro-
gram the two NACs with different, nonsteady codes, it is not permitted by any
authority. Use only one nonsteady code in
your LW-401 system.
Alarm Verification in the LW-401 is applied
globally to all selected zones. Therefore,
when a detector reaches its alarm threshold
and begins the Alarm Verification Time cycle,
any detector on any alarm verified zone will
react to smoke conditions as if its own Alarm
Verification Cycle had begun with the first
detector.
Generic Zone
The generic zone is activated (or alarmed)
by the output from another control panel.
This output should be made with a contact
device connected across the Generic zone.
When activated, it causes the notification
appliance circuits to sound and the appropriate initiating Zone LED to light. When the
input is deactivated, the NACs will silence.
The System alarm contacts do not change
state.
Notification Appliance Circuit (NAC or
Bell Circuit) Type (Program Level 4)
The LW-401 has two Notification Appliance
Circuits, each circuit is rated at 1.5 amps.
The Notification Appliance Circuits can each
be programmed for one of the following four
code choices:
1. Steady NAC
2. Temporal Code
When distributing power in the system,
remember that there are 3 amps available
between the two NACs and the auxiliary
output. Do not exceed 3 amps total current
draw from the system.
Simple Zone Code
Notification Appliance Circuits programmed
for simple zone code follow a pre-programmed code pattern. Devices are turned
on and off once for Zone 1 alarms, twice for
Zone 2 alarms, three times for Zone 3 alarms,
etc. The first alarm’s code is repeated for the
number of rounds programmed in the system, then the next alarm is reported. The
minimum allowable number of rounds is
three.
When all zones in alarm complete their
specified number of rounds in turn, the entire
sequence begins again with the first zone in
alarm. This sequence is repeated until the
system is silenced or reset.
The system operator cannot silence the
appliances, or reset the system, until the
programmed number of rounds of code have
been completed for each alarm. After silencing the appliances, the system reports a new
alarm via its particular code, followed by a
resound of all previously silenced alarms.
12
Page 16
LW-401 Operation, Installation, and Maintenance ManualLW-401
Set Output Control Matrix (Program
Level 5)
The LWZE-4A Zone/Output Expander module has four output relays and four open
collector outputs. The LWZR-8 Relay module
has eight output relays. Initiating Device
Circuits can be mapped to these outputs. Any
number of zones can be mapped to any
output. The first zone in alarm will turn the
output on. Also, any zone can be mapped to
any number of outputs. When the zone
alarms, all mapped outputs will turn on.
The outputs on the LWZE-4A and the
LWZR-8 are linked. The outputs are numbered 1 through 8. If a zone is mapped to an
output, for example output number 1, the first
output on the LWZE-4A and LWZR-8 will
turn on if both modules are in use.
Bypass Zones and Outputs (Program
Levels 1 and 2)
The LW-401 can bypass both Initiating
Device Circuits and relays or open collector
outputs on the LWZE-4A Zone/Output Expander module and the LWZR-8 Relay module.
• When a circuit is bypassed, the system
reports a trouble condition and the
Bypass LED will be on.
• When a zone is bypassed, the zone
trouble LED will also be on.
• When an output is bypassed, and both
the LWZE-4A and the LWZR-8 are in
use, the respective output on both cards
will be bypassed.
Set System Timing (Program Level 6)
The LW-401 has the following four timing
functions:
1. Verification Retard/Reset Timer
2. NAC Inhibit Timer
3. NAC Cutoff Timer
4. Simplified Zone Code Rounds
The Alarm Verification Retard/Reset time
establishes the delay time required to provide
an alarm verification cycle as determined by
the system owner or the local authority.
(Complete instructions for the proper selection of this timer follow.)
The NAC Inhibit and Cutoff Timers provide
automatic control of evacuation signals.
• The inhibit timer prevents any user from
silencing the notification appliances
before the selected time expires.
• The cutoff timer automatically turns off
all notification appliances after the
selected time expires.
Each timer has eight separate selections.
When the cutoff timer is set at
minutes), there is no automatic cutoff and
the appliances are energized until silenced
or reset.
The last timing function sets the number of
rounds of code for those systems using
Simple Zone Coding. (Please see the above
discussion of NAC types for a full explanation of Simple Zone Coding.) The minimum
number of rounds is 3 and the maximum
programmable number of rounds is 8.
No Cutoff
(0
Alarm Verification Retard/Reset Timer
Selection (Program Level 6-1)
The selection of the Alarm Verification
feature results in a delay of the system alarm
signal to the affected circuits. The total
allowable delay is 60 seconds. This delay,
the Alarm Verification time, is the sum of a
built-in 6 second system delay and the
programmed Retard/Reset time. The Retard/
Reset time can be set between 15 and 50
seconds, with 15 seconds being the programmed default. (See the definition of zone
types above for a further definition of the
Alarm Verification Time cycle.)

to, or greater than the Detector Start-up
Delay from the Table below. If not, the
Alarm Verification Time must be lengthened, or a new detector must be selected
for the installation.
3. Select the Retard/Reset time from the
programming instructions on page 18
which is closest to your result.
Example:
1. Alarm Verification Time required
by building owner = 30 seconds
2. Subtract the built-in, 6 second
system delay
3. Result = 24 seconds
Select a Retard/Reset Time of 25 seconds from the
table on page 18 of the programming instructions.
NOTE: All detectors in the table below, except the
8854/8843, can be used for this application.

Last Event Record (Test Level 4)
This feature records the zone in which the
last event occurred in each of four categories: Alarms, Troubles, Verified Alarms, and
Supervisories. This can be used for troubleshooting one-time reports of events.
Program Mode
The program mode allows the user to
change the configuration of the LW-401
system. The program mode has nine levels.
Each level allows the user to configure a
different function within the LW-401.
When the program mode is enabled, the
current programming levels and sublevels
display in turn on the seven segment display.
The order of the display is as follows:
1. the program level is displayed first
2. then a hyphen (-) is displayed
3. then the sublevel is displayed
4. then the display is blank.
The entire sequence then repeats.
In the programming mode, the four function
keys operate differently than they do in the
normal mode. Their functions are as follows:
The Acknowledge key toggles between the
Test mode, the Program mode, and the
Leave mode. The seven segment display
shows t, P, and L, respectively, to indicate
these modes.
The Reset key is used to select program
levels and options inside the programming
levels.
The Drill key selects options and toggles
options on and off.
The Silence key selects different sublevels.
Pressing silence when the seven segment
display shows L exits the user from the
program/test mode.
