The BSB FSD-TD Series SEVAC for smoke evacuation

Some applications may arise where dampers may be required to be driven normally closed and spring return open under the instruction of a smoke and/or fire alarm.

It must be stressed that this will also happen if power to the unit is lost.

These units are not fire dampers as they do not spring closed, but would be expected to stay open in the event of a fire.

They do not have thermal fuses, Building Control Authority approval must be sought before applying these products.
