Fire damper - FDMR
TPM 140/19
Design .61, 61S
■
Design with the communication and supply device BKN 230-
24-C-MP, and actuator BF 24-TN-ST (BFL 24-T-ST, BFN 24-T-
ST). It simplifies electrical wiring and interconnection of fire
dampers. Enables central control and checks of fire dampers
by means of a simple 2-conductor wiring and it also allows
connection to the system via MP-BUS communication.
Design 61. can be extended with an optical smoke detector
ORS 142 K (design .61S).
■
BKN 230-24-C-MP functions as a decentralized network
device for supplying the actuator BF 24-TN-ST (BFL 24-T-ST,
BFN 24-T-ST) further it transmits the signal informing about
the damper blade position OPERATION and FAILURE through
2-conductor wiring to the central.
■
Control command SWITCHED ON - SWITCHED OFF from the
central through BKN 230-24-C-MP goes through the same
wiring to the actuator.
■
To simplify the connection, the actuator BF 24-TN-ST (BFL
24-T-ST, BFN 24-T-ST) is equipped with connecting plugs that
are inserted directly to BKN 230-24-C-MP. BKN 230-24-C-MP
is supplied with a conductor and an EURO plug to be
connected to the 230V mains. 2- conductor wiring is
connected to BKN 230-24-C-MP by means of terminals 6 and
7. If the actuator is supposed to be controlled without any
signal from the central, it can be switched on by means of a
bridge between the terminals 3 and 4.
■
A green LED on BKN 230-24-C-MP is on when voltage is
present in the drive (AC 24V).
■
If the test button on BAT is pressed or if the power supply
(e.g. by a signal from ELECTRICAL FIRE SIGNALISATION ) is
disconnected, the damper blade position will be "FAILURE".
■
For design 61S the smoke detector is activated when smoke
spreads in air duct system. Deactivation of the smoke
detector alarm status is provided by interruption of supply
voltage for min. 2s.
■
The smoke detector is not part of the damper in the case of
dampers in diameters from DN 100 mm to DN 200 mm
(including). The smoke detector is supplied separately.
