General Smoke Control Interconnections

Overview

A Simplex Smoke Control System is usually part of a larger Simplex Fire Alarm System. The
Simplex Smoke Control System ties into the building air handling equipment, either dedicated,
non-dedicated, or both, to form the overall Smoke Management system for the building.
Since Simplex equipment is not the primary control equipment for a building's non-dedicated air
handling equipment, the interconnection between the Simplex Smoke Control System and the
non-dedicated air handling equipment is critical. This interconnection must be done in such a
manner to guarantee that the Smoke Control System takes priority, and that Smoke Control
System commands cannot be overridden by other building systems.
Although every application is different, the sections that follow describe some typical methods for
interconnecting to air handling elements to insure that Smoke Control System commands take
precedence and that accurate monitoring of the air handling system is fed back into the Smoke
Control System. Fan and damper control are shown in some detail to illustrate principles that can
be extrapolated to other more special purpose applications. These principles should be generally
applied to the detailed design of specific engineered smoke control solutions.
Smoke Control System operation is dependent both on the hardware and the control software.
The wiring diagrams shown in this chapter, must be used with appropriate programming to create
an operational control system.
