UltraVoice Manual - Alerting & Notification

with a local laptop computer running
SFCDWARE.
A. Operation
The results of a Quiet Test can be
obtained remotely using the SS2000
printout or the SFCDWARE control and
status monitoring software. The status
can also be obtained locally at the siren
site with a portable computer running
SFCDWARE. The actual amplifier
voltage and current are monitored with
Quiet Test providing a true indication of
each amplifier and load performance.
Calibration of the Quiet Test can be
performed by pressing switches 2 & 3
on the front panel at the same time.
Prior to performing a calibration the
speakers must be known good, as per
maintenance section.
B. Finding Faults
The siren automatically will do a reset
when running a Quiet Test. Reset prior
to a Quiet Test is not required. After a
test, the siren must be polled from the
SS2000. The SS2000 printout will
indicate the present siren status.
When using SFCDWARE, the controller
will automatically update the Quiet Test
status each time a new Quiet Test is
run. The status can be obtained from
the status detail screen and from the
Reports menu.

8.3 Digital Voice
When purchased, the Digital Voice
option adds a unit that is capable of
playing up to 1000 minutes of prerecorded
messages in any sequence
from 250 messages stored in an SD
Micro FLASH memory card that plugs
into the controller.
The digital voice messages will sound
best if recorded at the native sample
and bit rate rather than converting. The
sample and bit rates are; 8 kHz sample
rate, 8 bit, mono, with the level set so
that the peaks are at or slightly into the
limits.
These messages must be saved with a
DV#.wav naming format. The messages
will not be recognized otherwise. This
naming format will result in messages
DV1.wav through DV250.wav .
Converting files can cause noise.
If converting;
First; adjust the amplitude to insure that
the peaks are at or slightly into the
limits.
When converting from 16 to 8 bit, insure
that “Dithering” is disabled.
After conversion;
Run Amplitude Dynamics Processing
with flat gain for anything above -40 dB
and eliminating anything -40 dB or less.
The Digital Voice system can be
activated by using the radio receiver or
the siren controller panel switches. To
program activation codes with Digital
Voice Messages under them; follow the
