Screen Innovations Now Shipping Fontus

Provides two-way power and control over two-conductor wire.

Screen Innovations (SI) has announced the immediate availability of Fontus, a new product that enables its low-voltage motorized screens and shades to be powered and controlled via any type of traditional two-conductor wiring. SI’s Fontus allows integrators to utilize wire that may already exist inside a commercial building or home to connect screens and shades to a modern control system.

No bigger than a pack of gum and easily mounted to a DIN rail, Fontus can make a two-conductor wire perform 485 communication as if it were an eight-conductor wire. As long as there is a two-conductor wire available near the screen or shade location, Fontus, a dongle that plugs into SI’s new Janus power and control hub, converts low-voltage communications signals and power from a five-conductor system for distribution over two-conductor wire. The signal is decoded for reception at the screen or shade via a second Fontus dongle with no loss of signal.

Fontus can also be used to enable basic control of screens over two-conductor wire through dry and wet contact closures, IR input, and 485 signals. For example, when a door opens or a projector is activated, a contact closure or 12-volt trigger can signal a motorized screen to deploy.
