Smoke Exhaust Fire Damper provides high-temperature shut-off in a smoke-extract route. It allows the planned extraction path to operate and closes when the listed thermal release acts, linking the duct closure to the system sequence.
FEATURES AND BENEFITS

Position-feedback contacts and control options can report and coordinate the damper state with the extraction system.
APPLICATIONS
Where it is used
Smoke-exhaust duct routes
Use at the positions and operating states defined by the building smoke-control design.
SELECTION GUIDANCE
