This UHF Commercial Intercom
communicates with radios in the UHF 450-470 MHz frequency
The UHF Commercial Intercom has a small, rugged
metal case and is designed for industrial applications. It is
desk or wall-mountable with an optional wall-mount bracket.
If you want to add a louder external speaker,
you can plug an optional one into the speaker jack. You can also
plug in an optional external microphone. If you want to use a
headset, there is an optional headset that plugs into both the
speaker and microphone jacks.
The UHF Commercial Intercom includes an AC
adapter for wall power, plus you have the option of powering it
from a 12 volt DC car adapter.
See Figure 1 below for a description of the
intercom controls and connectors.
This unit can also be used in a vehicle by adding the 12 Volt DC Adapter below and a magnetic mount antenna.
If you are already using two-way radios, this
intercom can also be field-programmed to other UHF frequencies
to match those radios.
The Federal Communications Commission (FCC)
requires the owners of radios operating on these frequencies to
obtain a station license before using them.
"We purchased the MURS 4 Mile Range and
Commercial Intercoms because one of our Preschool classrooms
is far removed from the office - there was no way of
communicating electronically/ rapidly which is of special
concern in case of emergency. We decided to purchase the
outdoor Callbox XT to put out on our playground.
The classroom piece of the intercom has
saved much frustration and time simply by eliminating the
need for a staff member to either leave her classroom to
walk to the office or vice versa. Our office staff (one of
whom is handicapped) LOVES them because they don't have to
get up and down repeatedly to deliver messages/ gather
information, etcetera. It's all done through the new
intercoms. They provide peace of mind in case there is an
