Voice Alarm Modules
Voice alarm modules for the AFP-400 feature removable terminal blocks that
simplify installation and servicing of the control panel. These modules
include the Voice Control Module (VCM-4), the Voice Control Expander
(VCE-4), and the Dual Channel Module (DCM-4).
Overview
The following table contains descriptions of the voice alarm modules and the
components that come with each module.

Description
Components
Voice Control Module-4
(VCM-4)
A board that provides the AFP-400
with up to four Style Y or Style Z
speaker circuits. Moving a jumper
on the VCM-4 sets the VCM-4 to
drive telephone (FFT-7/FFT-7S)
circuits. When set for telephone
operation, a VCM-4 accepts its signal
directly from an FFT-7/FFT-7S.
VCM-4 board
four end-of-line resistors
(71252)
four dummy load
resistors (71245)
one 24-inch cable
assembly (71091) for
interboard connection
a set of slide-in speaker
labels
a set of slide-in
telephone labels
Voice Control Expander-4
(VCE-4)
A board that plugs into the back of
the VCM-4. This expands the voice
unit up to eight Style Y or Style Z
speaker circuits. When set for
telephone circuit operation, the
VCE-4 provides expansion for up to
eight Style Y or four Style Z fire
fighters telephone circuits.
VCE-4 board
four end-of-line resistors
(71252)
four dummy load
resistors (71245)
one 24-inch cable
assembly (71091)
three 1-1/4 inch cables
(75106)
Dual Channel Module
(DCM-4)
A two-board assembly (DCM-4 and
VCE-4) that provides the AFP-400
with capability to select one of two
audio sources for switching to a
selected speaker circuit. The DCM-4
can use up to four circuits.
DCM-4 board
VCE-4 board
four end-of-line resistors
(71252)
four dummy load
resistors (71245)
one 24-inch cable
assembly (71091)
four 24-inch cable
assemblies (71091) for
interboard connection
six 54 inch cable
assemblies (75071) for
connecting a DCM-4 to
an AMG-1 and
AA-30/AA-120s
a slide-in label set
