System Modules
The NFS-640 includes the ability to communicate with up to
eight conventional modules each with up to eight circuits. Any
mix of notification, relay, speaker, or telephone may be used.
Choose any combination of up to eight output modules: ICM/
ICE, CRM/CRE, DCM-4 or VCM/VCE. Panel modules mount
on either: the two far-right positions of the DP-DISP (next to
the primary display); or on any of the four positions on the
CHS-4N chassis (CHS-4MN kit required). NOTES: 1) These
modules/expanders are NOT to be used for releasing ap-
plications. 2) For additional information on these panel
output modules and expanders, see data sheet DN-6859.

modules. Includes CHS-4N, MP-1B (Module Dress Panel),
and Expander Ribbon Cable.
ICM-4RK: Notification Appliance Circuit
Module, provides four Style Y (Class B) or Style
Z (Class A) alarm Notification Appliance Circuits.
Maximum signaling current is 3.0 amps per
circuit or 6.0 amps per module, subject to power
supply limitations (includes auxiliary power
harness, ELRs and slide-in labels).
Includes ON/OFF controls and ON/OFF LEDs.
ICE-4: (at right) Notification Appliance Circuit
Expander, expands ICM-4 to provide a total of eight
Style Y or Style Z alarm Notification Appliance
Circuits. Circuit ratings are same as ICM-4. Note:
maximum of one per ICM-4RK. May
also be used to add four Notification
Appliance Circuits to VCM-4.
CRM-4RK: (at left) Control Relay
Module, four Form-C relay contacts, rated at 5.0
A, 120 VAC or 28 VDC (resistive) per circuit.
Includes manual ON/OFF controls and LEDs.
CRE-4: (at left) Control Relay Expander,
expands CRM-4 to provide a total of eight Form-
C relay contacts. Note: maximum of one per
CRM-4RK. May also be connected to add four
relays to ICM-4, TCM-2, TCM-4, or VCM-4.
VCM-4RK: (at right) Voice Control
Module provides four Style Y (25 and
70 V
RMS) and Style Z (25 VRMS only)
speaker circuits, eight manual select
switches and indicators, slide-in labels,
and plug-in terminal blocks. Move jumper to
convert to telephone circuits with remote ring
signal and local call-in flash. May be expanded to
eight circuits with VCE-4, ICE-4, or CRE-4.
VCE-4: (at right) Voice Control Expander adds
four circuits to VCM-4. Note: VCM-4/ VCE-4
combination must be eight speaker or
eight phone circuits.
DCM-4RK: (at left) Dual Channel
Module pro-vides four Class B (Style
Y, 25 & 70 V
RMS) or Class A (Style Z,
25 V
RMS only) speaker circuits plus
four channel A/B select relays. Not
expandable.
Other Option Modules
ARM-4: Auxiliary Relay Module, four Form-C
relays controlled by a relay module (CRM-4 or
CRE-4). N.O. contacts rated 20 amps; N.C.
contacts rated 10 amps at 125 VAC and 30 VDC.
Note: maximum of one for each CRM-4 or CRE-4.
VCC-1B: Voice Control Center. Provides a variety of user-
selectable tones on a single channel. Up to two different
tones or messages may be selected on a single channel.
Also provides optional digital voice message capability and
on-site programmable voice messages. Includes Audio
Message Generator (AMG-1) microphone, cables, dress
panels, and instructions.
VTCC-1B: Voice/Telephone Control Center. Provides all
that the VCC-1 provides plus two-way Fire Fighters Tele-
phone (FFT-7) capability.
TCC-1B: Telephone Control Center. Provides a stand-alone
two-way Fire Fighters telephone (FFT-7S).
Includes cables, dress panel and instructions.
RM-1/RM-1SA: Remote microphone assemblies, mount
on ADP-4 (RM-1) dress panel or CAB-RM/-RMR (RM-1SA)
stand-alone cabinets. See DN-6728.
AMG-E: (at right) Audio Message
Generator (without microphone). Order
in addition to VCC-1 or VTCC-1 if two-
channel system is required.
FFT-7/FFT-7S: Fire Fighters
Telephone control with master handset.
FTM-1: Firephone Control Module
connects a remote firefighter
telephone to a centralized tele-
phone console. Reports status to
panel. Wiring to jacks and handsets
is supervised.
AA-30: (at right) Audio Amplifier,
30 watts. Switch-mode power.
Includes amplifier and audio input
supervision, backup input, and automatic switchover, power
supply, cables. See AA Series data sheet, DN-3224.
AA-120/AA-100: Audio Amplifier provides up to 120 watts
of 25 V
RMS audio power for the NFS-640. The amplifier
contains an integral chassis for mounting to a CAB-B4, -C4, or
-D4 backbox (consumes one row). Switch-mode power.
Includes audio input and amplified output supervision, backup
input, and automatic switchover to backup tone. Order the AA-
100 for 70.7 V
RMS systems and 100 watts of power. See AA
Series data sheet, DN-3224.
VROM-(n): (at right) Factory-pro-
grammed message for installation in AMG-
1. Provides up to 24 seconds of evacua-
tion message on nonvolatile memory chip.
Choose one of many standard messages
available. Up to two of these messages may be installed in
one AMG. Includes VROM, instructions for
installation and operation, and written text of
message. See VROM data sheet, DN-3576.
VRAM-1: (at right) Field-programmed
memory to be installed in AMG-1. Provides
