DALI scene controllers: DALI-SC & SC-A
Description
DALI-SC is a module that enables scene selection commands for up to four scenes (A, B, C, D) to be sent to the DALI
circuit. Any standard momentary switch can be connected to the module. Its compact design means that DALI-SC can
be installed together with the standard momentary switches in a flush-mounted box, so set-up of the DALI circuit can
be decentralised.
The scenes are set on a rotary switch on the module.
The DALI SC module is multi-master-compatible so several control modules can be used in a DALI circuit.
DALI-SC-A is similar to DALI-SC. The only difference is that the programming mode is not activated in DALI-SC-A.
This prevents the DALI units from being reprogrammed unintentionally via the momentary switches.
Connection
The DALI-SC scene module is connected directly to the DALI circuit and does not need a separate power supply. It is
powered via the DALI circuit (current draw = 6 mA). It can be connected to the DALI circuit with either polarity.

½ CAUTION!
The connection leads between the momentary switches and the DALI-SC must not be lengthened. The DALI circuit
is not SELV. This means that the switches and cabling must be suitable for mains voltage.
