Converted my new Firex smoke detectors to fit the original hard wired detectors in less than a minute! Easy peasy!!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Fit as expected
  

*by M***H on Reviewed in the United States on August 18, 2024*

These adapters worked as expected so that I could install new smoke detectors using the original wiring and connector from the old smoke detectors.

### ⭐⭐⭐⭐ 4.0 out of 5 stars







  
  
    Convenient
  

*by T***L on Reviewed in the United States on September 14, 2021*

Would have been easy to pull the connections and install directly but this made it into a 30 second job instead of a 30 minute one. Now we are ready for any generational connection design that comes around.
