Design .61 with communication and supply device can be complemented with smoke detector
ORS 142 K. For supply and comunnication is used BKN 230-24-C-MP, which together with the
BF 24TN-ST (BFL 24T-ST, BFN 24T-ST ) enables central control and checks of fire damper by
means of a simple 2-conductor wiring and it also allows connection to the system via MP-BUS
communication. More information in the Belimo catalog.

1) Bridge has been installed by the manufacturer. If needed, it can be
removed ad replaced with a thermoelectric starting mechanism. If
terminals 1 and 2 are not interconnected, safety function is initiated.
2) Bridge can be used only for starting and without BKS24… !
