Firefighter Smoke Control Station (FSCS) / Smoke Purge System

UUKL & UUKL7 (Canada) listed.

California State Fire Marshal listed.


Graphics National Firefighters Smoke Control Stations/ Smoke Extraction Systems are designed for use in high-rise buildings and other facilities to manually control the fans and dampers designated for smoke removal during a fire emergency.  The panel is designed to work in conjunction with fire alarm and control systems that provides clear indication of the status and operation of the dampers and smoke control fans for responding fire department personnel. 

ON-AUTO-OFF fan control and OPEN-AUTO-CLOSE damper control is accomplished with three position rotary switches or toggle switches.  Status LED indicators show the following conditions:

WHITE - fans, dampers - ‘normal’ status.

RED - fans, dampers - ‘off’ or ‘closed’ status.

GREEN - fans, dampers - ’on’ or ‘open’ status.

AMBER - fans, dampers - ’fault’ status.

The switches and LED's are wired to customer supplied electronics or terminal strips which are sub-plate mounted in the enclosure.  A push button switch is supplied for testing the LED's.
