What are the limits on the number of fixtures?
There is no practical limit. EcoSystem ballasts (and BMF devices) can respond to inputs from any sensor or control connected to the same EcoSystem Bus Power Supply. Because each Bus Power Supply supports up to 64 ballasts, designers generally specify zones with up to 64 ballasts. Multiple bus supplies can respond simultaneously to the same input from a security, HVAC, or BMS system. Each ballast can accommodate one wall control, one IR or daylight sensor, and one occupant sensor. There are some limits on the number of sensors each bus can accomodate.
