Smoke Control Requirements

In addition to the information contained in each installation guide, the
following requirements apply when using the Infinet controllers and
repeaters in a smoke control system.
The SCX920S
• When using the SCX920S in a dedicated smoke control application,
the manual overrides must be disabled. The SCX920 installation
guide explains this process in detail.
• When using the SCX920S in a non-dedicated smoke control
application, you must do one of the following:
— Disable the manual overrides, or
— Locate the SCX920S in area only accessable to authorized
personnel, and provide an OVERRIDE status indicator on the
FSCS that turns on when the outputs are overridden. The FSCS
audible indicator must also turn on.
• If the AC input voltage is to be set to 24 V, an Andover Controls'
Listed transformer must be used to supply the 24V AC input power .
These transformers must be placed in a Listed enclosure and must be
wired according to the National Electric Code, as well as any state or
local regulations.
Table 3-1 lists the step-down transformers that are available from
Andover Controls.
