Challenges and Successes

  • Issue: TMCx witnessed AH-2 OSA damper is missing linkage rod on 1 of the 5 damper sections.

          Resolution: Mechanical contactor installed new damper rods at the outside air damper sections, TMCx verified operations with control contractor and test & balance contractor that we have required minimum outside air for court rooms.

  • Issue: TMCx witnessed existing AHU Supply Fans have existing Mitsubishi VFDs that are not setting up in fire mode and VFD key pad function keys are not disabling during smoke control scenarios.

          Resolution: Owner replaced old VFDs with new ABB VFD, drives are now configuring correctly when system is calling for fire mode during smoke control configuration.
