Kidde | Analog Addressable Dual Input Module for FX Series Fire Alarm Panels | FX-IDC2B

The FX-IDC2B connects two normally open initiating device circuits to a Kidde FX Series fire alarm control panel on a single SLC address pair. Class B wiring, rotary addressing, and slide-switch preset for alarm or supervisory operation - one module handles two zones without doubling your device count on the loop.

Built for the commercial fire alarm installer

Mounts in a standard North American 4-inch square box (2-1/2 in. deep 2-gang or 1-1/2 in. deep standard). Rotary TENS and ONES switches set the address with a screwdriver - no laptop required for basic commissioning. The module uses two consecutive SLC addresses (second auto-assigned), so plan your address map accordingly. Compatible with Kidde FX Series 64-point and 1000-point control panels. UL listed.

Key advantages

• Two IDC circuits per module: monitor two zones from one SLC address pair, reducing module count and wiring runs
• Rotary address switches: set addresses 01-63 (64-point panel) or 01-126 (1000-point panel) with a screwdriver
• Slide-switch preset: configure for alarm or supervisory without front panel programming
• Ground fault detection: pinpoints the specific module where a wiring fault occurred, cutting troubleshooting time
• Bicolor LED status: flashing green for normal, flashing red for active - visible confirmation at the device
• Standard box mounting: fits 4 in. square x 2-1/2 in. deep 2-gang box or standard 4 in. square box 1-1/2 in. deep

System requirements

Requires a Kidde FX Series intelligent fire alarm control panel. Communicates over the SLC loop at 20V peak-to-peak maximum. Wire with 12, 14, 16, or 18 AWG (16 and 18 AWG preferred). Each IDC circuit requires a 47 k end-of-line resistor (P/N: EOL-47) for Class B operation.
