2 DALI Interface
Intesis gateway and its DALI interface complies with the new DALI-2 (IEC62386) standard thanks to its DALI-2
certification.
Intesis gateway enables the conection of up to 64 DALI/DALI-2 ECGs and 64 DALI-2 sensors. In current version of
the device, the following device types are supported:
• General requirements (Part 101)
• Part 201: DALI Fluorescent lamps (DALI type 0)
• Part 202: Self-contained Emergency lighting (DALI type 1)
• Part 207: LED modules (DALI type 6)
• Others (Multiple DALI types)
• Sensors (Part 103):
• Part 303: DALI-2 Occupancy sensors
• Part 304: DALI-2 Light sensors
The maximum number of DALI devices (ECGs and/or input devices) depends on the sum current consumption of the
specific devices. Intesis gateway supplies bus power of 235 mA for power supply of the DALI devices, so if all input
devices (sensors) in the bus consumed 5 mA then we could connect 64 ECGs (standard defines max. consumption
allowed for these devices is 2mA) and 16 sensors.
64 ECGs * 2 mA + 16 sensors * 5 mA = 208 mA < 235 mA * 90%
As the standard recommends, don’t use the guaranteed current to calculate the maximum number of DALI devices,
leave 10% of the current for dynamic processes into account.
