DALI PROFESSIONAL Frequently Asked Questions
What is the max. cable length in OSRAM DALI PROFESSIONAL system?
Is it 300 m in total for all 4 DALI lines or 300 m per each DALI line?
DALI lines are released for 300 m with 1.5 mm
2
standard copper installation wires. The DALI PROFESSIONAL
controller CONT-4 provides 4 electrical independent DALI lines which can be wired in opposite directions with the
CONT-4 in the center.
What is the wiring concept for DALI projects?
DALI line topology is linear or star up to 300 m max. distance at min. 1.5 mm
2
copper wire. But no closed loops, no
ring topology. Do not mix with TOUCH DIM applications. Avoid shortcuts. DALI wiring needs only basic insulation to
mains voltage, so standard installation cable NYM 5x1,5 mm
2
is recommended.
How many DALI ECGs can be used?
In DALI there are 64 DALI ECG addresses per DALI line which results in 128 mA DALI current consumed by these
ECGs. Because we have 4 DALI lines in DP CONT-4, there can be used max. 256 ECGs.
For ECG with more addresses per unit (e.g. OSRAM OTi DALI 75 with optional 4 addresses) the max. number is
reduced accordingly.
How many DALI ECGs can be controlled individually in OSRAM DALI PROFESSIONAL?
DALI PROFESSIONAL provides in total 256 DALI ECG addresses divided into 4 DALI lines. To control these
individually you need 256 buttons or 64 pushbutton couplers which exceeds the maximum DALI current. With this you
can only control 220 ECGs individually. To achieve a full individual control of all 256 ECGs, we recommend to use 22
Glasstouches (12 buttons each) combined with the according e:bus gateways / power supplies.
How many DALI input devices can be used?
In our system there are 64 DALI Input Devices addresses per DALI line. Because there are 4 DALI lines in DALI
PROFESSIONAL Controller CONT-4 max. 800 mA DALI current can be used in total including the ECGs. This leaves
approx. 280 mA for Input Devices if all 256 ECGs are installed. The remaining DALI current to be consumed by input
devices depends on mix of types (OSRAM DALI Pushbutton Coupler 6 mA, OSRAM DALI Sensorcoupler 5 mA). For
input devices with more addresses per unit (e.g. OSRAM DALI Sensorcoupler with 2 addresses), the maximum
devices number by addresses is reduced accordingly.
How many pushbuttons can be used in OSRAM DALI PROFESSIONAL?
Final number is depending on mix of products in the configuration. Theoretical there are 64 input device addresses per
DALI line. But in most applications the limiting factor is the current : each DALI line of CONT-4 provides 200 mA DALI
current which has to be shared between ECGs and input devices. So if all 64 ECGs are installed you can add 12
OSRAM DALI Pushbutton Couplers (48 buttons) or 7 OSRAM DALI Pushbutton Couplers (28 buttons) and 5 OSRAM
DALI Sensorcouplers (5 light sensors + 5 occupancy sensors).
How many sensors can be used in OSRAM DALI PROFESSIONAL?
Final number is depending on mix of products in the configuration. Theoretical there are 64 input device addresses per
DALI line. But in most applications the limiting factor is the current : each DALI line of CONT-4 provides 200 mA DALI
current which has to be shared between ECGs and input devices. So if all 64 ECGs are installed you can add 14
OSRAM DALI Sensorcouplers (14 lightsensors + 14 occupancy sensors) or 7 OSRAM DALI Pushbutton Couplers (28
buttons) + 5 OSRAM DALI Sensorcouplers (5 lightsensors + 5 occupancy sensors).
What is the maximum pushbutton distance to OSRAM DALI Pushbutton Coupler?
We allow a maximum wiring length of 2 m from pushbutton to OSRAM DALI Pushbutton Coupler. We recommend to
install the pushbutton coupler behind the pushbutton in an installation box using the wires delivered with the device.
What is the maximum sensor distance to OSRAM DALI Sensorcoupler?
A maximum wiring length of 5 m from Sensor to OSRAM DALI Sensorcoupler is allowed. Recommended is OSRAM
MULTI3 wiring material like Y-Connector.
