F-R60
Design
Material Composition
The F-R60 damper has a galvanized sheet metal casing, blades from non-asbestos calcium silicate board with
polyurethane foam seals for cold smoke and an intumescent seal that expands in case of fire. Ethylene-propylene
rubber as duct seal. The product contains no hazardous substances, except for the solder in the thermal fuse, which
contains a milligram of lead. All materials are processed in accordance with local regulations.
Activation Types
Manually Operated Fire Dampers
By default, manually operated fire dampers are supplied with manual control, optionally with micro switches. In case of
fire, the fire damper is closed automatically The actuating mechanism is activated when the temperature of the air in
the duct reaches 74 °C and the damper closes within 10 seconds after fuse melts.
•
H0
Fire damper with an activation mechanism with a cover, manual crank and with a spring return release mechanism
activated by a fusible thermal link set to 74 °C.
•
H2
Fire damper with an H0 activation mec open and closed indication with AC 230 V or AC/DC 24 V contact
switches.
Actuator Operated Fire Dampers
By default, actuator operated fire dampers are supplied with an actuator with micro switches, optionally with a
communication and power supply unit. A fire damper can be equipped with a spring return actuator which can be
closed by a command from the building management system, or after the breaching of the thermoelectric fuse.
Actuator operated fire dampers are equipped as standard with a thermoelectric fuse, that activates the closing of the
damper after the reaching or exceeding the ambient temperature of 72 °C. The actuator power circuit is interrupted
and its spring closes the damper blade within 20 seconds.
