File Explanation:
The stairwell fan is controlled by a set of nested “if-then-else”
statements. The nested “if-then-else” statements prioritize the control
modes as follows:
• The FSCS overrides: ON-OFF
• Automatic Smoke Control
• Weekly Self-Test
The SmokeSelfTest program in the CX9200 performs the weekly self-
test by setting the value of DefaultFanPosn.
