Overview

The Kidde KA-F Quick Convert Adapter is a six‑pack solution designed to simplify upgrading Firex alarms to Kidde. The compact adapters fit into your existing wiring harness and allow seamless interconnection with other Kidde devices, preserving signaling across compatible units without a full rewiring project.

How it works

Use the KA-F adapter to install a Kidde alarm into a Firex wiring harness. The setup preserves the original interconnect pathway and enables additional Kidde products to communicate with the new alarm, giving you a streamlined upgrade path for your safety system.

What’s included

This six‑pack provides multiple adapters for homes or small facilities, offering flexibility when replacing several Firex bases. The KA-F adapters are engineered to work with Kidde’s AC/DC alarm line for reliable operation across different models.

Key benefits

  • Facilitates quick installation using your existing wiring harness
  • Enables interconnection with other Kidde products for shared signaling
  • Specifically designed for replacing Firex models FADC, ADC, and AD
  • Compatible with all AC/DC Kidde smoke and combination alarms

Compatibility and interconnection

The adapter is tested for interconnect compatibility with Kidde alarm models including 1235, 1275, 1276, 1285, i12020, i12040, i12060, i12080, i4618, PE120, PI2000, KN-COSM-IB, KN-COB-IC, KN-COP-IC, and RF-SM-ACDC when used with the specified Firex bases. This means you can extend reliable signaling across a range of Kidde devices after replacement.

Installation tips

  • Power off the circuit before starting any swap
  • Confirm the Firex base is one of the supported models (FADC, ADC, AD)
  • Test the interconnect after installation to ensure proper signaling

Why consider the KA-F six‑pack

Having six adapters on hand supports multi‑unit upgrades in a single project, reducing downtime and simplifying planning. While results depend on your existing wiring and housings, the KA-F aims to provide a practical, user‑friendly upgrade path that aligns with Kidde’s broader alarm ecosystem.
