Smoke Detector REPLACEMENT

Reviewed: 08/27/2019 by Dr. Jeff Tokryman

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.

Reviewed: 05/23/2019 by Ann Donoghue

I tried to purchase smoke alarms locally to replace the outdated ones that came with the house.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.

I replaced the 10-year old 5204 alarms in my house with the recommended 5304 alarms. Replacement was easy using the existing bracket & wiring -- twist the old unit off & unplug followed by plug the new unit in & position-&-twist onto the bracket. The 5304 was on back-order but arrived much to my delight BEFORE the promised date. I just asked the company via their website how to dispose of the old units as they contain a small amount of radioactive material and await their response.
