Frequently Asked Questions (FAQ)
Q1:How does the smoke exhaust fire damper work?
A:Under normal conditions, it stays open for ventilation. When the duct temperature reaches 280°C, the thermal fuse breaks, and the damper closes automatically to stop fire/smoke spread.
Q2:Can it be linked to a fire alarm system?
A: Yes. Electric-actuated models can receive signals from the fire alarm system to open or close as required.2
Q3:Do you offer both round and rectangular models?
A: Yes, both shapes are available, and we also support custom sizes.
