Kidde | FX Series Single SLC Loop Expansion Card for FX-1000 Intelligent FACP, 250 Device Addresses | FX-SLC1

The FX-SLC1 adds a full 250-device SLC loop to a Kidde FX-1000 intelligent fire alarm panel without replacing the main board. Plug the card into an open expansion slot, wire a Class A or Class B loop, and the panel auto-enrolls the new devices on power-up. For FX-64 panels, the same card replaces the standard 64-point loop controller.

Built for the fire alarm installer

Each SLC loop supports up to 250 intelligent addressable device addresses - 125 detectors and 125 modules. Wiring runs up to 20,000 feet per loop in Class B or Class A configurations, with built-in ground fault detection and up to 64 isolators per loop for fault segmentation. The card draws 24 VDC from the panel's main board at just 55 mA standby and 80 mA in alarm on a fully loaded loop.

Key features

• 250 device addresses per loop: 125 detectors and 125 modules on a single SLC circuit
• Class A or Class B wiring: choose the loop configuration that matches the job and AHJ requirements
• Plug-in installation: mounts directly to the FX-1000 main circuit board - no additional enclosure needed
• Up to 20,000 feet of loop wiring: covers large commercial buildings on a single loop run
• 64 isolators per loop: segment the SLC for fault isolation without losing the entire loop
• Low current draw: 55 mA standby, 80 mA alarm - minimal impact on panel power budget

System requirements

Requires a Kidde FX-1000 or FX-64 intelligent fire alarm control panel. On the FX-1000, the FX-SLC1 occupies one of two available expansion slots, expanding system capacity in 250-point increments up to 1,000 total device addresses. On the FX-64, it serves as a direct replacement for the standard loop controller (64 addresses).
