UltraVoice (UV)
Do not use this voltage source for radios, which draw more than 1.5 A of current in
transmit. Use both grounds and both +12 Vdc connections for current handling. If a
higher current output is required, purchase a 24 Vdc to 12 Vdc voltage converter. The
UVT series models includes this converter. Do not use one of the 12 Vdc batteries to run
the radio equipment.
1. AUDIO—Connect the Ult control panel Receive Audio input to the de-
emphasized audio output of the radio. Use shielded audio grade cable and keep
wire runs as short as possible. The Receive Audio level can vary from 300 mV to
3 V
p-p
unclipped.
2. The Transmit Audio output is adjustable from 50 mV to 3 V
p-p
.
3. C.D.—The carrier detect signal from the radio must pull to ground when active.
The radio carrier detect signal is useful for controlling live PA. When the
C.D. signal is removed from the controller for over 5 seconds, the controller
automatically cancels the PA function eliminating the need to broadcast the cancel
tones over the siren.
4. PTT—The PTT output pulls to ground when active to key the radio.
UV25ST Option
The UV25ST allows the end-user the capability to reduce audio output from the 70 V
RMS
standard to the 25 V
RMS
standard. This option is beneficial when using the UV controller
in an indoor warning application.
The UV25ST has a similar form and fit as the UV400 amplifier. In an indoor application,
the UV+ can accommodate up to four UV400 amplifiers and four UV25ST. For every
UV400 amplifier used, purchase a corresponding UV25ST.
The UV25ST plugs into the unused amplifier slots following the UV400 amplifiers.
Model UVTD-IP
The UVTD-IP combines the characteristics of a UVTD with Serial to Ethernet conversion
capabilities. This allows serial devices to communicate over an Ethernet network and
provides audio decoding of digitized audio sent over the network.
The converter is configured with its own fixed IP address and port number. When packets
of data are received over the Ethernet port that are addressed to the board’s IP and port
number, they are converted to serial data and sent out over the serial port. Likewise, any
data coming into the serial port is converted to TCP/IP data packets and sent out over
the Ethenet port to the server’s IP address. The unit also contains a digital to analog
converter. This allows specially configured incoming data packets to be converted to
audio, which is then filtered and sent out over a 600 ohm audio port.
