INTRODUCTION
ATTENTION INSTALLER: To assure a trouble free installa-
tion, please read these entire instructions through once
before beginning.
The Sigtronics UltraSound Emergency Intercom System,
when used with Sigtronics noise attenuating headsets
provides the emergency apparatus crew with clear, hands
free, voice activated (VOX) intercom. The system also allows
full radio monitoring at all headset positions as well as radio
transmit capability from selected headsets via Push-To-Talk
(PTT) switches.
Applications: The unit is designed for fire apparatus, rescue
and ambulance vehicles, marine emergency equipment,
airport ground vehicles, and mobile emergency command
centers.
Voice Activated Intercom (VOX) feature allows “hands
free” communication between headsets connected to the
UltraSound unit. Start speaking and the intercom turns on
instantly to relay your message clearly to the other headsets.
Stop talking and it turns off to reduce background noise.
Up to Four Headset Positions can be connected to the
UltraSound unit models US-45S and US-45D. Up to six for
models US-67S and US-67D. More headset positions can
be achieved by wiring additional jacks in parallel. Only one
headset, however, can be plugged into paralleled jacks at
one time. This paralleled jack scheme is most commonly
used on pumper trucks at the pump panel. In this case, the
Driver plugs his head- set into his jack while driving. He then
unplugs and plugs into the pump panel when he arrives on
scene.
