1 When using PZ-60DR-E or PZ-41SLB-E to connect multiple Lossnay units
● Connect the sensor to the Lossnay set to "Main".
● It is not necessary to connect to any Lossnay with the "Sub" setting.
● Connect any sensor, etc., with the external change input to the Lossnay unit set to "Main".
● Any Lossnay with the "Sub" setting will operate at the same High/Low setting as the Lossnay with the "Main" setting
when there is sensor signal input.
2 When using M-NET for a group of multiple units
● Even if the units are in the same group, you can only change operation to High/Low for Lossnay units connected to the
sensor.
