Alarm message selection is via DIP switch settings on the 4003 Voice Controller
Assembly. The host FACP activates its Notification Appliance Circuits and
initiates the alarm at the VCP. The Voice Controller generates the selected
alarm message and routes it to the amplifier. For "Adjunct" operation, an
Initiating Device Circuit is required to supervise trouble conditions associated
with the Voice Controller Assembly, Amplifier Board Assembly, 4003 SIGcard,
and Power Supply. These and all normal audio card troubles map to an on-board
relay. Activation of this relay causes an Open Circuit trouble on the host
monitor zone. Activation of the Manual EVAC switch causes an alarm on the
host monitor zone. This alarm must energize all signal circuits in the host
FACP. The VCP plays the alarm message and activates the 4003 SIGcard
points.
For stand-alone paging applications, the 4003 VCP provides manual control for
microphone announcements or pre-recorded messages. Digitized messages are
played using the "Manual EVAC" or "Message Two" switches. The microphone
is used to make live announcements. The trouble output activates on any card
trouble status, allowing field wiring of an IDC. Connection of an IDC allows a
separately-mounted FACP to monitor for trouble conditions.
