The Glass Touch T12 User Terminal is part of the innovative, future-oriented Glass Touch User Terminal Series. It features an even glass front with 12 buttons plus one On/Off button. Every button can be freely assigned to any conceivable function (e.g. adjusting brightness, speed and choice of lighting programs) by connecting to the e:cue Butler XT for stand-alone replay or to the e:cue Lighting Application Suite (LAS) 5.0. Embedded LEDs and a built in beeper deliver a direct audio-visual feedback to the user. Contact between a Glass Touch T12 and a Butler XT is made by a 2-wire, polarity- and topology-free e:bus connection, which is capable of running up to 8 Glass Touch User Terminal devices per bus. The easy mounting into in-wall mounting boxes does offer a simple method to develop new and upgrade existing lighting control scenarios. Different designs are available on request.
