By code does the power feeding smoke damper actuators need to be on emergency power?

RE: connecting smoke damper actuators
I saw some smoke dampers years ago that were gravity operated and held open with fusible links. There was an integral electric heater to melt the link. They were of course "One Time Only Devices" and had to be replaced after every use. We lost a couple during test and commissioning. They would operate on either a high ambient temperature or from a signal from the fire alarm panel. They were powered from the fire alarm system.

I've been away from North America for quite awhile now and away from comercial for even longer. And yes, I do remember now that it was a fire damper. I stand corrected.
