Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

About Product Overview

Power your safety system with confidence using the First Alert Kidde Hard-Wired Photoelectric Adapter Plug—a 12-pack built for dependable, 120-volt operation with photoelectric smoke alarms. This boxed set is designed to support consistent power to compatible detectors while eliminating the need for frequent battery changes.

Key benefits

  • 12 adapters in a boxed, ready-to-deploy bundle—perfect for multi-room homes, rental properties, or property-management needs.
  • Hard-wired 120V power ensures reliable operation for photoelectric smoke alarms without relying on replaceable batteries.
  • UL Listed, CSA Listed, and ETL Listed—third-party safety certifications you can trust for compliance and peace of mind.
  • Specifically designed for use with photoelectric, hard-wired smoke alarms in the First Alert and Kidde lines.
  • No batteries included and no test/reset button on the adapter itself—use your alarm’s own controls to test and maintain safety routines.

Why it matters

Photoelectric sensors excel at detecting smoky, smoldering fires earlier than some other technologies, giving you valuable early warnings. When paired with these hard-wired adapters, your detectors stay connected to the home’s electrical system, reducing routine battery changes and helping maintain a ready, alert fire-safety setup.

Ideal use cases

  • Installing or upgrading to reliable, continuously powered smoke alarms in bedrooms, hallways, kitchens (with proper placement), and living areas.
  • Replacing worn or damaged adapter plugs across a two- or three-story home, apartment, or small duplex.
  • Stocking up for property managers or landlords who equip multiple units with compliant, photoelectric detectors.

What’s included

  • 12 hard-wired photoelectric adapter plugs, packaged in boxed sets for easy storage and quick deployment.

Note: This adapter is intended for use with compatible hard-wired photoelectric smoke alarms. Ensure electrical work complies with local codes and follow the alarm manufacturer’s installation guidelines. If you’re unsure about compatibility with your specific detector model, consult your alarm’s manual or the installer.

Their Counter
Try local first · we'll wait

The stores we send you to are local and independently run — often for generations, the kind of place where someone behind the counter knows the regulars. We don't own them. We just think they deserve the foot traffic. They can put most of what we sell on their next truck. Ask there before you check out here.

About our directory. National Hardware Group is an independent retailer and directory. The local stores we list and link to are separately owned and operated — we have no ownership stake in any of them, and most pay us nothing to be included. That includes plenty of stores flying a co-op banner that people don't realize are locally owned and run, not operated by a corporation. Store owners can choose to upgrade their listing for an enhanced presence or pickup features, but the base directory is free, and inclusion is never a paid endorsement.
