Motorized Dampers Power Source

Do motorized dampers (not fire smoke dampers) need to be on generator power?
They are interlocked with an exhaust fan and there is a generator in the building.

Is the exhaust fan on generator power?

The motorized damper is actually installed on a supply fan's duct. Supply fan is interlocked with an indoor AC unit. Both AC and fan are on normal power.

Then, No, it does not need to be on the generator. It would serve no purpose.
