Designed for Crash Fire Rescue vehicles, Sigtronics

UltraSound CFR Intercoms enhance crew safety and efficiency.

Our CFR intercoms are engineered to interface with all mobile
radios and will allow transmission on multiple radios from two
or more positions. And with Voice Activation our intercoms
turn on instantly when you start speaking and turn off when
you stop, eliminating the constant noise pick-up through the
headset microphone.

Radio transmit is by way of the headset microphone, this elimi­nates the need to reach for the hand mic. Placement of the push­to-talk switches can then be in the most accessible locations.
Intercom function is automatically disabled during transmission
so that only the voice of the person transmitting goes over the
air, however his voice is heard by all crew members.

Crash Rescue vehicles are big, powerful, and often loud.
Combine the UltraSound CFR intercom with a set of our noise
attenuating headsets for a system that will deliver the maximum
in crew hearing protection.

Versatility: Systems are available for all CFR apparatus and

emergency vehicles. Our standard system will provide four
headsets positions with two radio transmit positions.

Simple Installation: The UltraSound CFR is small, light weight

and mounts above or below the panel and adjusts for easy view­ing. The intercom package comes with all the necessary mount­ing hardware for installation in the apparatus.

Small rugged mounting boxes, (1⁵⁄16˝ x 2˝ x 2˝) are provided with
every unit to accommodate headset jacks and push-to-talk
switches. Complete and easy to follow installation and operat­ing instructions are provided with each system.

The industry standard of excellence in aircraft high noise
environment intercoms since 1974, Sigtronics introduced the
same advanced technology to emergency apparatus intercom
systems in 1989.

To insure the highest quality and reliability, all Sigtronics prod­ucts are designed and manufactured in the U.S.A.

Fail Safe: The mobile radio, hand microphone and speaker

will function normally with the intercom installed. The trans­mit keying circuit is fully isolated to provide for all radio keying
configurations.
