INTRODUCTION

The LW-401 is a microprocessor based fire
and life safety system with four conventional
initiating device circuits (up to 8 with the
addition of the optional LWZE-4A or
LWZE-8A zone expander). All basic alarm
and trouble functions are annunciated and
controlled from the LW-401 front panel (See
Figure 1) which consists of:
• Seven segment numeric display
• Four user-control switches
• Red and yellow LEDs for each of the
eight zones
• Six system status LEDs
Key features of the LW-401 are:
• 2 Class B (Style Y) +24 VDC notification
appliance circuits (NACs) rated at 1.5
amps each.
• Silenceable/Non-Silenceable notification
appliance circuits (NACs).
• Fully supervised initiating and notification
circuits.
• Initiating and notification circuits power
limited.
• 4 Class B (Style B) 2 wire initiating
device circuits that are expandable to 8
circuits.
• Supports up to 30 non-shorting devices
per initiating device circuit.
• Selectable alarm verification option for
each initiating device circuit.
• One person system test with or without
audible confirmation.
• User-alterable factory installed configu-
ration.
• One Form C system Alarm relay
• One Form C system Trouble relay
• Seven segment numeric status display
• Six LED status indicators
• Easy-to-use front panel function keys

• Alarm Coding (March Time, Temporal, or
Simplified Zone Code) and Non-
Silenceable output option.
• Easy-to-use built-in diagnostics.
• 24 hour re-sound for Alarm and Trouble
conditions that are not restored to normal
after being acknowledged.
• Optional LWZE-8A module converts the
system to four Class A (Style D) Initiating
Device Circuits and two Class A (Style
Z) Notification Appliance Circuits and
also provides four additional Class A
(Style D) Initiating Device Circuits.
• Optional LWZR-8 module provides eight
programmable Form C relays.
• Optional LWRA-8B/W module provides
remote annunciation for eight zones with
16 LEDs. Up to two may be used.
• Optional LWCT-1 module provides
Leased Line/Municipal Tie connection.
