SCS Series Smoke Control Station

SCS-8, SCE-8, SCS-8L, SCE-8E

The SCS-8 Smoke Control Station and optional SCE-8 Smoke Control Expander, SCS-8L Smoke Control Lamp Driver, and SCE-8L Smoke Control Lamp Driver Expander are used with the NOTIFIER Fire Alarm Control Panels, NCA or NCA-2 Network Control Annunciator displays, or the INA, to provide the capability to control and display the status of AHU fans or dampers. Each SCS can control and monitor eight AHU fans or dampers.

Features & Benefits:

  • Capable of two modes of operation: Firefighter’s Smoke Control Station (FSCS) or Heating, Ventilation, and Air Conditioning (HVAC)
  • Communication to the SCS is accomplished over a two-wire serial interface employing an EIA-485 communication standard

  • Power for the SCS is provided via a separate 24 VDC regulate power loop.  If power is lost, a trouble signal will result at the control panel
