Firefighter's Smoke Control Station
The Firefighter's Smoke Control Station (FSCS) is a graphic
annunciating control panel that gives firefighters information about the
state of the smoke control system as well as manual control over all of
its components. The FSCS should be located in a secure room or cabinet
to prevent unauthorized personnel from tampering with it. The room or
cabinet should be clearly marked so that firefighters can quickly locate
the FSCS.
The Fireman's Smoke Control Station panel has a diagram of the
building showing the entire smoke control system, along with status
lights and override switches for all of the system's components. The
diagram of the building should include all smoke control zones, all of
the ducts leading to and from the zones with arrows indicating the
direction of air flow in the ducts, and a clear indication of which zone
each piece of equipment serves.
The panel must have controls to activate all fans, dampers, and other
equipment related to the smoke control system. These manual controls
must be able to override all automatic control of smoke control
equipment. In particular, the FSCS must be able to override:
• Hand/off/auto switches
• Local start/stop switches on fan motor controllers
• Freeze detection devices
• Duct smoke detectors
The FSCS must not override such safety controls as:
• Electrical overload protection
• Maintenance personnel's electrical disconnects
• High limit pressure switches
• Any fire/smoke damper thermal control as required by UL33
(standard for heat responsive links for fire protection service), heat
responsive links, or UL555S (the standard used for leakage rated
dampers for use in smoke control systems).
In non-dedicated systems, local motor controller's hand/off/auto
switches can remain in-circuit with the FSCS panel. But, they can
remain in-circuit only if the switches are in a locked room accessible
only to authorized personnel. Also, if such a switch is thrown, a trouble
alarm must sound in the building's main control center.
