Notifier SCS-8L — Smoke Control Station lamp driver master module with eight switch groups, expandable to 16 with an SCE-8L expander, for a custom graphic smoke control annunciator.
SCS Series stations are used with the Notifier NFS2-3030 panel or the NCA-2 network annunciator for Firefighter's Smoke Control Station (FSCS) applications, and with the NFS-320, NFS2-640, NFS2-3030 and NCA-2 for HVAC applications. Each switch group controls and monitors a fan or damper, or a group of fans or dampers. The SCS-8L is the lamp driver version of the SCS-8: instead of on-board switches and LEDs, each group has contacts for a three-position switch and three lamps or LEDs mounted on the graphic.

Installation notes
- The SCS-8L must be installed in a UL-approved custom graphic annunciator panel and backbox
- Each group connects a three-position switch and three lamps or LEDs; the module also drives two LEDs and one momentary switch
- HVAC mode is for fan shutdown and building HVAC only and is not consistent with UL and NFPA smoke control standards
- Loss of the 24 VDC power loop causes a trouble at the control panel

FAQ
What is the difference between the SCS-8 and SCS-8L?
The SCS-8 has on-board toggle switches and LEDs. The SCS-8L is the lamp driver version, with contacts for remote switches and lamps or LEDs on a custom graphic annunciator.
Which panels work with it?
The NFS2-3030 or NCA-2 for Firefighter's Smoke Control Station applications, and the NFS-320, NFS2-640, NFS2-3030 and NCA-2 for HVAC applications.
How many fans or dampers can one module handle?
Eight switch groups, or 16 with an SCE-8L expander. Up to 32 annunciator addresses give a system maximum of 512 switch groups.
How is it powered?
From a separate 24 VDC regulated power loop, with communication over a two-wire EIA-485 circuit.
