Impressive, flexible control system
It doesn’t matter whose light fitting or driver you are using, if it is DALI it will work on a DALI control system. Up to 64 light fittings /drivers can be controlled per DALI line, buildings have multiple DALI lines. Wiring to a DALI fixture requires a standard active neutral/earth, plus two DALI control lines (not polarity sensitive). The “A” in Dali stands for “addressable” this means the driver can be “addressed” by software and told what it is and where it is. Dali drivers are always powered on in standby, waiting for a Dali signal to "turn on" and go to a dim level. Very impressive, very flexible but often needs complex expensive control systems and an Integrator to make it all work. The basics of DALI are, excellent stable dimming 100-1% and some drivers to 0.1%. Additional 2-core building control cable is required. Fittings are connected to the Dali line and then addressed – no switched circuits.
Dali drivers can also be wired in “broadcast” mode. Wired in a traditional circuit, the Dali “broadcast signal is sent to each driver in the wired circuit, On/Off dim Up/Down.
