Outstations (Remote Switching Panels):

Imagine a room with two entrances. It would be convenient to control the room's lighting with two switches, one next to each door.

An outstation is a switch panel that also controls a dimmer but is located in a different part of the room from the dimmer itself.

This gives you a choice of controlling the circuit either directly from the dimmer switch panel or remotely from this other switch (which is referred to as an outstation).

The P800 domestic dimmer and the Futronix Enviroscene and PFX commercial dimming systems feature outstations.
