INTRODUCTION
ATTENTION INSTALLER: To assure a trouble free installa-
tion, please read these entire instructions through once
before beginning.
The Sigtronics UltraSound CFR Emergency Intercom System,
when used with Sigtronics noise attenuating headsets pro-
vides 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 airport CFR fire appa-
ratus, rescue and ambulance vehicles, marine emergency
equipment, 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 CRF unit. Up to eight positions for Dual-CFR
installations (Simultaneous Transmit). More headset posi-
tions 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 system is most com-
monly used at the pump panel. In this case, the Driver plugs
his headset into his jack while driving. He then unplugs and
plugs into the pump panel when he arrives on scene.
