*1: Multi sensor connection: 1st sensor module can connect up to 4 sensors equipped with SA11 SENCOM SA, via BA11 junction
box.
*2: WE10 is an extension cable stretching between SA11 and sensors. WE10 is universal to connections if needed.
Connect a SA11 SENCOM Smart adapter to a sensor. Connect SA11 to FLXA 402 via WU11
SENCOM cable.
Read each exclusive user’s manual for information on SA11 Smart Adapter, WU11
Interconnection/Extension Cable for SENCOM Products, WE10 extension cable, BA11 Active
