The following paragraphs describe the requirements for the various types of programs that can be
implemented using the Simplex Smoke Control System.
Emergency operation programs have the following functions:
• Zoned smoke control to activate from automatic devices only.
• Manual devices may cause any operation that is common to all smoke strategies
(e.g. Stairtower Pressurization).
•
Automatic operation programs have the following functions:
• The first alarm in sets the operation strategy for smoke control. Subsequent alarms do not change the
smoke control strategy operation. The first alarm in sets that zone ON, and the other zones OFF. (See
Equations 9, 11, 13, and 15.)
• The program checks proof sensors and reports equipment operation to the FSCS or, if such proof is not
received within a specified time from activation it reports any failure to the FSCS. The delay time to
allow sensors to operate is set at ten seconds for conversion in testing. This delay time can be increased
to accommodate the time it takes for the equipment to respond. The maximum delay time is 60 seconds
for fans (Equations 19 through 24) and 75 seconds for dampers (Equations 25 through 46).
• Manual operation of the FSCS control switches overrides the automatic program. Manual commands
have a higher priority than automatic operations. (See Equations 47 through 74.)
Dedicated smoke control system weekly self-test programs have the following functions:
• Begins Saturday at 0000 hours if there is no alarm.
• Run once. Any failures sound an audible fault signal and light an indicator on the FSCS showing the
device that failed. In addition, the program displays “Weekly Smoke Control Self-Test Failed (Time &
Date).”
