The Custom Control equations in this example are written for 4100U/4100ES based smoke control
system, and show how to implement the Dedicated Smoke Control System Weekly Self-Test
requirement described on the previous page.
Note: The points mentioned are representative of any system. Your system uses different points
to provide the Inputs and Outputs. The following equations are provided as reference
material. The syntax may be slightly different than that shown. However, the logic and
content are the same.
The following list gives the Custom Control program (equation) number followed by a title
(or label) for the program.
