Damper is delivered in closed position.
When electric actuator is connected to the
power supply damper will open. When the damper
reaches the end position(damper open), in which it
is blocked, the electric actuator will stop. Closing
fire damper takes place automatically when a
power failure occurs. Thermal tripping device that
comes with fire damper causes power circuit break
at a temperature of 72 °C (inside or outside duct).
If checking is needed for proper functioning of fire
damper, pushing the switch on the thermal tripping
device will close damper. When switch on tripping
device is released, the damper will open.
Damper can be opened without connecting to a
voltage with enclosed Allen key, by turning in the
direction of the arrow on electric actuator (clockwise).
After release of Allen key, damper will go to closed
position.
