When the centralized control
equipment are located at
several places.
iTM
Unified ON / OFF
controller (DCS301BA61)
Up to 8 controllers can be
connected.
The advantages when the centralized control equipment are connected to A.
If the centralized control equipment are connected to A, it is still possible to have a centralized control, even if the
power supply of other circuit connected to the centralized control equipment is shut off. (even if the power is shut off
due to long vacation etc.)
Caution:
1. It is not recommended to connect the centralized control equipment on (α1), (α2), (α3), as there is a risk to loose
control over all systems.
Ex.; If intelligent Touch Manager (iTM) is connected on (α1), and System1 shut down, control over System2 and
System3 units is lost.
