Like smoke dampers, fan control and overriding the HVAC control is a basic function of the
Simplex Smoke Control System. General principles for interconnection to a non-dedicated fan are
shown in Figures 4-8 and 4-9.
In a non-dedicated fan control application, a 4090-9120 6-Point I/O Module is used to provide
inputs to a fan controller for smoke control override and monitor the feedback from the controller.
The wiring between the module and the fan controller is unsupervised, so the module must be
mounted within three feet of the controller in accordance with NFPA 72.
