Answer This Question

A:  Hello. Yes, the KA-F2 adaptor of this pair will work with most of our current hardwired alarms. It will not work with the 900-CUAR or the 900-CUAR-V.

    Q:Will this work with a FireX Model G-6 91301?
    by|Feb 28, 2024
    1 Answer
    Answer This Question

    A:  No. This G-6 alarm was made back on the 301st day of 1991 and only had a 10 year lifespan. There is no direct replacement for your alarms. That being said, you can use any of the Kidde current hardwired smoke alarms to replace your older alarms. You will have to take down all of the older alarms before putting up any new alarms. You will have to change out and rewire the wiring harness plugs at each location. There are no adaptors for the wiring harnesses you have now. You will have to change out the mounting brackets at each location but that will just take a screwdriver to change out. All of your alarms will need to be replaced due to age.

      A:  Hello. These are the adaptors. These are the adaptors for certain older FireX and First Alert/BRK wiring harness plugs to adapt the plugs to Kidde alarms.

        Saved Time, But Hard To Snap In Place
        I am in the midst of replacing all seven smoke detectors in my house with four Kidde TruSense Smoke and three TruSense Smoke and CO detectors. Most of my (extremely) old detectors were FireX, and these adapters saved me some serious rewiring. It didn't look pleasant to pull the jumble of wires and wire nuts out of the ceiling and hardwire the connectors that came with the new detectors! My first attempt to connect the adapter to the original wire harness took about 25 minutes and resulted in sore fingers for days. The dang thing just didn't want to snap in place. This problem appears to be a result of the center tab. I'm not really sure why it's there, since it doesn't clip in place like the side tabs. It doesn't appear to provide any structural advantage, and is very much in the way. When I was finally able to get the side tabs to snap into place over the old harness, the center tab was bent pretty heinously. It might have been easier to just cut it off with a hacksaw. After struggling with the second install for several minutes, I learned my lesson and went in search of a pair of needlenose pliers. That made it much easier to get the side tabs to snap into place, and it was off to the races after that. I have now replaced five out of seven. One needs to be rewired, because it does not have a compatible harness (but I already knew that and only bought six adapters). The other is 15 feet up on my vaulted bedroom ceiling, and I have to drag up the 10 ft ladder from the garage. I'll hopefully get around to that before 2021! I was torn between giving this three or four stars, but I opted for four since it saved me from rewiring. I do wish that they sold these individually for FireX or First Alert. I'm going to wind up throwing the six unused First Alert adapters in a drawer somewhere, and that seems like a waste. Selling them individually might have cut the price in half as well.

          I purchased new kidde smoke detectors to replace my old one and these adapters make installation ...
          I purchased new kidde smoke detectors to replace my old one and these adapters make installation super easy. My previous smoke detectors were already hardwired so it literally took minutes to install, i simply detached the old ones attached the adapter and attached the new smoke detectors. I highly recommend buying the adapters for easy installation!

          As it turned out, these were not needed to hardwire the smoke detectors. Therefore, can't evaluate their value. Ordered because the website showed them frequently purchased with the smoke detectors.

          easy to replace older hardwired units. Make sure you get adaptors for the hardwired systems. Snaps in perfectly
