Simplex 4100U Application Guide

Non-dedicated Smoke Control System wiring adds a layer of complexity, as the Smoke Control
System must take control of the fans and dampers from the HVAC system. This introduces the use
of bypass and cutoff relays not needed in a Dedicated Smoke Control System. The following
sections illustrate some examples of non-dedicated damper and fan control.
Damper control and overriding the HVAC control of the damper is a basic function of the Simplex
Smoke Control System. Interconnections for dampers are shown in Figures 4-6 through 4-9.
Control of the damper is accomplished using the 4090-9118 Relay IAM. The Relay IAM
communicates with the FACP via the Simplex IDNet Signaling Line Circuit (SLC). When
commanded by the FACP the Relay IAM activates the smoke control override relay and supplies
power to the pressure switch to close the damper.
