Electric Actuator Schischek ExMax
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 is it 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.
