SystemSystem
The SC-300 counter-top ticket window intercom is designed for
applications where a cutout in the barrier is impractical.
How It Works...
Two-way communication is accomplished through the use of
speakers and microphones on each side of the partition. The inside
Master unit is equipped with a 15" gooseneck microphone, power
on/off switch, power-on LED, and external volume controls. The
Remote unit is vandal resistant with all controls located within the
metal housing.The SC-300 provides electronic two-way hands-free
audio communications (duplex) between a partition. The SC-300 is
equipped with a factory adjusted VOX switch to prevent ambient
noise (below 85 decibels) from activating the unit. The SC-300
contains two voice channels, each incorporating a microphone
amplifier, VOX switch, compressor, and a power amplifier. The
sound amplifier does not exceed a 0.2% total harmonic distortion
rating.
How To Install...
The SC-300 comes ready to operate. The prism units are quickly
and easily mounted on the counter-top on opposite sides of the
barrier. They can be positioned back-to-back (as shown) or
randomly. The unit with the gooseneck microphone and controls
goes inside the booth; the unit without controls is mounted
outside the booth. There are two ways to install the SC-300:
either run the cable between the units through a small hole in the
barrier ('A' type mounting), or under the counter-top ('B' type
mounting) (as shown on the left).
