Perfect Applications for HavenTech SC-350 Window Intercom
The SC-350 is the smart choice for installations in which a full-depth window intercom is impractical,
such as when mini-blinds or fire shutters are installed in the window frame. The base unit and remote units
are "hands free", and the base unit incorporates an 18” gooseneck mic to allow for conveniently positioning
the base unit when staff is using a computer.
