This was a replacement that lasted about 9 years. So far so good! The reason I purchased this brand was bc my house is already hardwired for this particular alarm.

Replacement Smoke and Fire Alarm

Reviewed: 03/23/2021 by Jeff C

I built and took occupancy of my home in the summer of 2004. I am fortunate to never have a need for the system, experts recommend replacing all smoke/fire detectors every ten years. I neglected the advice and got sixteen years. I was overdue. The 5304 model is the replacement for the originals. They matched well. I replaced the original plastic mounting brackets and electrical connections. I found them to be easier to install than anticipated. I purchased and received a bulk price of 12 units which increased the discounts. The spring sale made the price more affordable. My family is worth any price. I am embarrassed I didnt do this sooner. Happy to have new equipment and a lower risk should a fire or harmful smoke develop.

I had an installed 5204 in the house I bought recently that I couldn't stop from chirping despite a new battery. I reviewed and then confirmed with your in house customer service that the available replacement 5304 would fit in the house without any rewiring or refitting base .Perfect replacement once I figured out that the base plate was different. It was included and I just replaced the old one with the new base by using same two screws.

After reading the product info on the website, I purchased the 5304 alarm to replace the previous model that is no longer available. It would have been much easier to use the same base plate so all I would have had to do was plug in the power source. On the good side..at least I did not have to replace the power source plug. Once installed everything is fine.

I tried to purchase smoke alarms locally to replace the outdated ones that came with the house. After two tries, I finally gave up and looked up the company that was on an old ones. I explained that I wanted a smoke alarm that I did not have to rewire and provided the number on the expired alarm. The company had what needed, but I would have to change the base plate one time. They changed to a universal base plate but the plug was the same as my former smoke alarm. I was apprehensive as my ceilings are 10 feet tall and I would be on a 7 foot ladder. Easy! It only took me a few minutes to change each one. Thank you Universal Security Instruments. I feel safe again.

I ordered 5 of these smoke alarms to replace the 10-year-old models in my home one started malfunctioning and I decided to replace all of them. I am not experienced enough to install new electrical wiring. Online research showed this is the replacement model for the old fire alarms. This model allowed me to use the same mounting bracket and quick connector wire for the electrical hookup. The quick connector was a little difficult to remove but after the first installation, I'm a pro! Ordering was easy, the product is reasonably priced,and it arrived quickly. I plan to order my next replacements in 10 years when these need replacement. AWESOME.
