I found the ordering process and the advice given for the correct smoke alarms to be top notch. I had ordered 30 replacement detectors for myself and 5 of my condo neighbors. Received them promptly and at an excellent price. I was able to replace all of the units in a short time because they were a direct replacement. I will be introducing Universal Security at the next Homeowners meeting. Thanks for your help.

Great, direct replacement - 01/22/2019
Reviewer: BILLY GRAHAM
Our house has seven interconnected model 1204 smoke detectors the 1204HA is a direct replacement. All were due for replacement due to age, the 1204HA is perfect, I did not need to change the base. Just remove old detector from the old base and plug in the new detector to the original, already installed base, pull the battery tab, and twist new detector on to the old installed base. PERFECT! Actually easier than changing the battery! Great solution!

My alarms were 13 years old and started beeping off an on. Replaced all batteries each year during Thanksgiving. Discovered that these have a useful life of 10 years. Removed one of the 6 alarms looked up the company and found the replacement. Arrived when they said they would. It took me 15 minutes to replace 6 alarms using the original base, that's including moving an 8 foot ladder. Perfect replacements.

I replaced older units that were 15 years old with the same units and it saved me a lot of time not have to rewire the base to the electrical. I just plugged the new into the old wiring and it worked fine. This unit also seems to be improved over the previous version. As a side note the green light also is a bit brighter and serves now as a night light.

Reviewer: E. N.
With the help of Nicole R. I found out the exact new model number that replaced our existing old fire & smoke alarms. Also Michelle M. emailed the explanation as to why fire & smoke alarms need to be replaced every 10 yrs. Ours where like 15 yrs old and started randomly beeping even with fresh batteries. Good lesson learned!! Never knew we needed to do more than just check battery! We sleep better knowing all 8 smoke & fire alarms are replaced and have new batteries. Green light is on. Thank you for your customer service via email and phone.

Reviewer: John Farina
I had to replace my existing Smoke and Fire alarm since they were over 10 years old law is need to been newer than ten years. What was great is that I did not have to remove the base no rewiring necessary. I simply unscrewed the alarm and re-crewed in the new one. Perfect fit. Took me only an hour to do so for 8 units and would have been much less if some of them were not on 15 foot ceilings. Very pleased. Easy to order and arrived quickly. Also a great price these sell on amazon for $30 dollars and as I ordered 8 this was quite a saving. I am very pleased!

We bought our home 2 years ago, it was built in 2005, so 13 years old. Our smoke detector began incessantly beeping at odd hours no matter how many new batteries we put in. Buying the replacement was cheaper here than on Amazon & it arrived within a week. Fit perfectly and no more beeping. We'll be back when others need replacing.

Product was exactly as advertised, a direct replacement for my obsolete 1208. If there was one thing I could find any fault with, it would be that the RED LED is so dim and overpowered by the green, that I thought that it was not working because I could not see it, even at night, but I was able to determine that it was indeed working.

The customer service representatives from Universal Security Instruments have been helpful and even sent me a link to a video on how to install the new style alarm I purchased. It helped the process go much faster and everything is working well. I'll definitely be purchasing from their website directly from now on instead of through other online store fronts.

Replacement for 13 year old units - 04/17/2018
Reviewer: David Ziemer
Ordered these to replace 13 year old builder installed units. I simply used the main units that easily slipped into the exiting hard-wired base. Had the whole project finished in less than 30 minutes, including ladder set up and take down. Very pleased. I bought the battery only unit to put me over the free shipping amount and will put it in the garage.

Replaced all Fire alarms - 01/23/2017

We had older alarms in the home that was wired and also with battery back up, they all are replaced now with updated models. The USI web lets you know the correct model # to use if the older one is outdated and also lets you know that each one talks to each other one installed.

Ordered this product to replace a defective detector in my house. Because this was the exact same model that was installed when my home was built I didn't need to change and rewrite the ceil mounting plate, just unplugged the old unit and installed the new one in literally two minutes. I will definitely be ordering replacements for the rest of the house since all the units are now over ten years old.

Just installed today. The shipments went to a neighbors blame Fedex on that one. Ordering process was easy and so was installation. I found the comparison charts very useful. I suggest staying with the version you already have installed in your home so you don't have to strip wires.

I didnt realize smoke detectors expired - 11/22/2015
Reviewer: Todd Burgess
My home was built in 2004. During the recent time change, I was inspecting the batteries and saw the expiration date stamped into the detectors. After a bit of research and confirming with our fire protection company @ work, I realized I need to replace my 7 smoke detectors which were now almost 12 years old. The USI model in my home, tied into my alarm system and fire sprinklers were easily available on the USI website as a direct replacement the originals. I emailed the company about bulk pricing and although my count of 7 didn't meet bulk pricing they offered me a 15% discount. The shipping was ground and took about a week but all arrived in great condition. I replaced both the detectors and the base as the color on some had yellowed due to exposure to sunlight. Overall am very pleased with the product, website purchasing and customer service. Way to go USI!

My second time ordering. I can distinguish between the older alarms and the new by the subtle light that radiates from the new alarm. Very pleased so far.

Great price - 08/27/2015
Reviewer: Ed Roland
I was able to find the exact smoke alarms that were installed in our house 2002, and that simplified replacing them. The website was easy to use, and Universal Security Instruments had the best price for the same product on other websites.

These were replacements for our existing smoke alarms that were 12 years old. The changing from the old to the new was very easy. I'd buy this product again for our next house.

Fire Alarm with Battery Backup USI-1204HA - 08/18/2015
Reviewer: M. Wilkins
The USI-1204 smoke & fire detector has proven to be a very reliable & trouble free detector. I have several throughout the house. Each & every one of my detectors has lasted over 5 years before requiring either a simple battery or detector replacement.

Perfect Fit - 08/10/2015
Reviewer: Tangi Gary
I bought these smoke detectors to replace some that were about 15 years old. They were hardwired without battery back up and these new ones are also hard wired but do have battery back up and they just plugged right into the original plug. I didn't have to do any wiring.

Perfect replacement - 08/03/2015
Reviewer: Yuri Dedulin
I have 8 of these detectors in my home. The existing 11 years old units had started to fail. Easy install Snapped right into place without issue and it comes with a 9V heavy duty battery.The new units fit in the base of the existing unit, so I didn't have to replace the bases. Purchased 4 of these units replacing older unit and will be purchasing a couple more. A lot cheaper than on Amazon.

Had to order two new smoke alarms because hubby and father in law each broke battery compartment trying to get battery out operator error. So there you have it. They had the model I needed which worked out perfect and the battery compartment seems to open just fine

Great customer service - 06/27/2015
Reviewer: Donna J Dell
I ordered 6 new smoke alarms. When I spoke to the customer service rep with questions about my order, she was very knowledgeable about the product I wanted to order. My order came at the time I expected it and was well packaged and just what I ordered. I would use this site again to place similar orders. Next up....Carbon monoxide alarm.

I installed replacement smoke detectors, due to the fact that my old ones were about ten years old. I needed assistance from this company by phone as I was having some difficulties. The person on the phone helped me solve the problem and install the alarms properly.

Great Replacement! - 04/30/2015
Reviewer: Jefferey Meierhofer
I bought 7 of these to replace existing alarms in my home that was built in 2006. The manufacturer recommends changing these out every 10 years but I decided to get ahead of the game a bit after 9 years. The performance on these models has been great and I expect the same 9-10 years of work out of the new ones I just installed. Incidentally, I only needed the inner parts as the outer shell was already wired and connected from the first USI-1204HA alarms that were wired in with the house. The coloring on the outer shell has not faded over the last 9 years and the new inner parts fit beautifully and matched in color too. Very satisfied!

Fire Alarm - 01/30/2015
Reviewer: Jeff Leveille
I have used this brand of fire alarm in the past and purchased 5 replacement alarms after installing the initial one about 7 years ago. It was nice to be able to install just the replacement and not have to re-install all the mounting brackets as well. The model number was on back order at the time I placed the order but I still received the order within a ten day period.
