Design .41 or .51 with actuating mechanism can be complemented with smoke detector
ORS 142 K. The voltage can be AC 230 V or 24 V DC. Design with voltage AC 230 V is equpped
with Communication and supply device BKN 230-24-MOD and with actuating mechanism BF
24-TN (BFL 24-T, BFN 24-T).
The smoke detector is activated when smoke spreads in air duct system. Deactivation of smoke
detector is provided by interruption of supply voltage for min. 2s.
Signalisation of damper blade position "OPEN" a "CLOSE" is provided by two limit switches..
