The pneumatic schematic for RPM4’s with two Q-RPT modules is the same as for the single Q-RPT 
modules in Figure 8 with the following exceptions: 

•

  If both modules use the barometer, the barometer is connected to teed to both module barometer 

connection points.  

•

  An exception is the combination of an Axxx with SDS (<A10M) and a G15K or BGxxx shown below. 

Axxx Q-RPT <A10M with G15K or 

BGxxx
