Voice alarm modules for the AFP-300/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). For instructions on mounting modules, refer to Section 2,

Table 4-10 contains descriptions of the voice alarm modules and the components that
come with each module.
Table 4-10 Voice Alarm Modules
Module Description Components
Voice Control Module-4
(VCM-4)
A board that provides the control
panel 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
Fighter’s 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
control panel 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 (15831)
