Simplex 4100U Application Guide

4-8
Like smoke dampers, fan control is a basic function of the Simplex Smoke Control System.
General principles for interconnection to a dedicated fan are shown in Figures 4-4 and 4-5.
In a dedicated fan control application, the 4090-9118 Relay IAM is used to provide inputs to a fan
to turn it ON and monitor the feedback from the controller. The wiring between the Relay IAM
and the fan is unsupervised, so the IAMs must be mounted within three feet of the controller in
accordance with NFPA 72.
