Window Master FlexiSmoke WSC 520 - CAN Bus Connectivity; X2 More FlexiSmoke ventilation panels can be connected via X2.

23
X2
More FlexiSmoke™ smoke ventilation panels can be connected together via X2.
It is possible to connect up to 31 20A-sections
The smoke panels are coupled via X2 in the last 20A section in panel x to the first 20A section in panel x+1. See
Section 9 "Cable plan for connection to WSC 5xx" and drawing below. The CAN cable between two smoke ventilation
panels must not exceed 250m and the total cable length must not exceed 1000m.
When the panels are mounted in the same smoke zone the panels are connected via CAN1.
If the panels are mounted in two or more smoke zones the panels are connected via CAN1 and CAN2 in separate
cables.
A red DIP switch is mounted on the back plane for the modules. Factory setting is set to OFF.
When connection more panels the switch on the first 20A section in the first panel and the switch on the last 20A
section in the last section are to be set to ON.
