SystemSystem

The SC-300 counter-t op t icket window intercom is designed for
applications where a cutout in the barrier is impractical.

How It Works...

Two-way c ommunication is ac c omplished through the use of
speakers and microphones on eac h 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 c ontrols. T he
Remote unit is vandal resistant with all controls located within the
metal housing.The SC- 300 provides elect ronic two-way hands- free
audio communications (duplex) between a partition. The SC-300 is
equipped with a fact ory adjusted VOX switc h to prevent ambient
noise (below 85 decibels) from ac t ivating the unit. The SC-300
contains two voice c hannels, eac h incorporating a mic rophone
amplifier, VOX switch, compressor, and a power amplifier. T he
sound amplifier does not exceed a 0.2% total harmonic distortion
rating.

How To Install...

The SC-300 comes ready t o operate. T he prism units are quickly
and easily mounted on t he c ounter- top on opposite sides of the
barrier. They can be positioned bac k-to-bac k (as shown) or
randomly. T he unit with the gooseneck microphone and c ontrols
goes inside the boot h; the unit without c ontrols is mounted
outside the booth. There are two ways to install the SC-300:
either run the c able between t he units t hrough a small hole in the
barrier ('A' type mounting), or under the counter-top ('B' type
mounting) (as shown on t he left ).
