F-B90
Multiblade Fire Damper
Description
Fire dampers are part of passive fire protection, with a compartmentalized design to prevent the spread of toxic gases, smoke and
fire.
All standard Systemair fire dampers are designed and certified in accordance with the EIS criteria according to EN 1366–2.
The fire dampers together with their installation form an integral part of the fire resistivity rating.
F-B90 fire dampers are designed for the installations listed in their Data Sheet. Their installation is described in the User Manual of the
fire dampers.
All fire dampers are supplied with a mechanism with, optionally with micro-switches, actuator and/or power and communication unit.
A fire damper that is equipped with a spring return actuator can close the damper following the command from the building
management system, or after the thermoelectric fuse is melted. Actuator-operated fire dampers are standard equipment with a
thermoelectric fuse, that activates the closing of the damper after the reaching or exceeding of the ambient temperature of 72°C. The
actuator power circuit is interrupted and its spring closes the damper blades within 20 seconds.
