MAC Closed-Loop Door Operator Upgrade Kit
KONE Spares offers an upgrade kit designed to convert compatible Type M, PMSSC, and HPMSSC MAC door operators to closed-loop operation.

The upgrade may be beneficial when:
- Heavy doors at lobby or other floors cause the MAC operator to perform slowly.
- Debris in door sills regularly causes the operator to stall out and not make-up interlocks.
- Shaft wind causes problems with doors making-up.
- Consistent, repeatable door operation is required in varying environmental site conditions
Installation is estimated at four to six hours. Actual installation time may vary based on equipment condition, configuration, and site conditions.
