Kidde KA-F2 Quick Convert Adapter – 2-Pack for FireX to Kidde Hardwired Alarms

Upgrade FireX to Kidde with ease

The Kidde KA-F2 Quick Convert Adapter is built to bridge FireX hardwired wiring to compatible Kidde alarms. It lets you replace older FireX units without reworking the ceiling harness, preserving your existing wiring path and reducing installation time.

Designed for practical compatibility, this adapter supports Kidde AC and DC hardwired alarms that rely on the standard Kidde harness. It is not a universal adapter, so a quick compatibility check is essential before purchase. When both the FireX model being replaced and the new Kidde alarm use the designated harness, retrofit becomes a smoother process.

What you may gain in everyday use

• Preserves the existing ceiling wiring, speeding up replacements for homeowners and professionals alike.
• Works with a wide range of Kidde AC/DC hardwired alarms that use the Kidde harness.
• Provides a straightforward retrofit path when upgrading from specific FireX models to Kidde models.

Compatibility and usage tips

• Primary FireX models to replace: FADC, ADC, AD.
• Target alarms: Kidde hardwired models that use the standard harness (AC or DC).
• Not universal; confirm both FireX model and Kidde alarm compatibility before installing.
• For accurate guidance, refer to the alarm manufacturer specifications and installation instructions.

The KA-F2 is sold as a 2-pack, offering flexibility for multi-unit installations or keeping a spare on hand. Pair this adapter with the appropriate Kidde alarm to achieve a streamlined retrofit that minimizes disruption and maintains a tidy ceiling line. Always follow local codes and manufacturer directions during installation.
