S9208 8 Nm, ON/OFF control- Safety Damper Actuators
The S9208 security fire electric, spring-return damper actuator series has been specially developed for the motorized operation of fire protection dampers. When the control signal is applied the actuator drives the damper to the operational position, while evenly tensioning the integrated spring. After a power failure, the stored energy in the spring immediately brings the damper to the safety position. Manual operation is automatically canceled when the actuator is in electrical operation.
