Product overview
Actuators
R (R-S)
Manual operating mechanism, optionally with end
switches (R-S). In case of fire, the fire damper closes
automatically. Damper closing can be initiated
either by thermal fuse melting, or by manual acti-
vation on the operating mechanism. Upon closure,
damper blade is locked in closed position and can
only be opened manually. Thermal fuse melting
point is 72 °C.
EMS-S
Electromagnetic operating mechanism, comes with
end switches as standard. In case of fire, the fire
damper closes automatically. Damper closing can
be initiated either by thermal fuse melting or remo-
tely by triggering the electromagnet. Electromagnet
is constantly under power and activates closing of
the damper blade in case the power cuts out. Upon
closure, damper blade is locked in closed position
and can only be opened manually. Thermal fuse
melting point is 72 °C.
M230-S
Belimo 230 V electro motor operating mechanism,
comes with integrated end switches. In case of
fire, the fire damper closes automatically. Damper
closing can be initiated either by thermoelectric
release device or remotely by triggering the electro
motor. Upon closure, damper blade is locked in
closed position and can be opened by sending a
signal to electro motor. Standard thermoelectric
release point is 72 °C, optional 95 °C.
M24-S
Belimo 24 V electro motor operating mechanism,
comes with integrated end switches. In case of
fire, the fire damper closes automatically. Damper
closing can be initiated either by thermoelectric
release device or remotely by triggering the electro
motor. Upon closure, damper blade is locked in
closed position and can be opened by sending a
signal to electro motor. Standard thermoelectric
release point is 72 °C, optional 95 °C.
M24-S-ST
Belimo 24 V electro motor operating mechanism,
comes with integrated end switches. In case of
fire, the fire damper closes automatically. Damper
closing can be initiated either by thermoelectric
release device or remotely by triggering the electro
motor. Upon closure, damper blade is locked in
closed position and can be opened by sending a
signal to electro motor. Standard thermoelectric
release point is 72 °C, optional 95 °C. Actuator is
additionally equipped with connection plug for easy
connection with power supply and communication
modules.
EX
ATEX rated fire dampers are equipped with
Schischek ExMax actuators, Exbox-TT thermal swit-
ches and ExBox plenum boxes. Optional casing can
be produced in AISI316L stainless steel.
