The FX-SLC2 adds two independent SLC loops to the Kidde FX-1000 intelligent fire alarm control panel, expanding system capacity by 500 addressable points without adding a second panel to the job. Each loop carries 250 device addresses (125 detectors and 125 modules), letting you scale a single FX-1000 to cover larger buildings or multi-wing facilities from one location.

Built for the commercial fire alarm installer

Both loops support Class A or Class B wiring, so the expansion matches whatever riser design is already in place. The card draws just 45 mA standby per loop from the FX-1000's 24 VDC bus, keeping the power budget predictable even at full device load. Up to 64 isolators per loop provide proper fault isolation across large floor plans without eating into device capacity.

Key benefits

  • Doubles FX-1000 capacity to 500 addressable points without installing a second panel or running additional network wiring
  • Class A or Class B wiring per loop to match existing riser design and AHJ requirements
  • Low current draw at 45 mA standby / 70 mA alarm per loop - keeps the host panel's power budget intact
  • 64 isolators per loop maximum for reliable fault isolation in large commercial and institutional buildings
  • Standard 12-18 AWG terminal connections for common fire alarm wire without special tooling
  • 66 ohm max loop resistance / 0.5 uF max capacitance allows extended SLC runs across large facilities

System requirements

Requires a Kidde FX-1000 intelligent fire alarm control panel with an available SLC option card slot. The FX-SLC2 installs directly on the FX-1000 main board. No additional power supply needed - the card draws from the panel's existing 24 VDC bus.

FAQs

How many addressable devices does the FX-SLC2 add?
The FX-SLC2 adds 500 addressable points across two independent SLC loops. Each loop supports 125 detector addresses and 125 module addresses, for a total of 250 devices per loop.
Does the FX-SLC2 support Class A wiring?
Yes. Each SLC loop on the FX-SLC2 supports both Class A and Class B wiring configurations, so you can match the existing riser design or meet specific AHJ requirements.
What panel does the FX-SLC2 work with?
The FX-SLC2 is designed exclusively for the Kidde FX-1000 intelligent fire alarm control panel. It installs in an available SLC option card slot on the FX-1000 main board.
How many isolators does each SLC loop support?
Each loop supports a maximum of 64 isolators, combining both isolator bases and isolator modules. This applies to the total count across both device types on each individual loop.
What wire gauge do the SLC loop terminals accept?
The FX-SLC2 terminal connections accept 12-18 AWG (0.75-2.5 mm²) wire, compatible with standard fire alarm cable.
