Questions & Answers

I have old alarms that are bad will these hook up to same wiring??

I have old alarms that are bad will these hook up to same wiring??
Asked by: buzz
Hello Buzz. If your old alarms are not Kidde Products, then you will need to take down all of the old alarms before putting up any new alarms and you will have to change out the wiring harness plugs by rewiring at each location and change out the mounting bracket rings. We are Kidde Product Support at 1-800-880-6788. Thank you for you for your interest.

Do these Fire X smoke detectors meet the 10 year requirement?

Do these Fire X smoke detectors meet the 10 year requirement?
Asked by: Howard
I was very much surprised to see the response posted by a Kidde representative on August 8, 2017, stating, "These units are compliant with the 10-year requirement". Maybe in some States, but not in Florida!! Kidde has on their own website, see below link, titled "New Florida Law Will Help Save Lives, "Jan 1, 2015 Mebane, NC, US MEBANE, N.C., Dec. 29, 2014 — In an effort to reduce residential fire fatalities, new smoke alarm regulations will go into effect Jan. 1 for Florida families whose homes have battery-powered smoke alarms. As outlined in the Florida Building Code, starting in 2015 homeowners must install 10-year, sealed-battery smoke alarms when replacing outdated or non-working alarms or installing new ones. Alarms like Kidde Worry-Free sealed-battery smoke alarms comply with this code change. Kidde Fire Safety, a leading manufacturer of residential fire safety products, is a part of UTC Building & Industrial Systems, a unit of United Technologies Corp. (NYSE: UTX)". "Millions of Florida homes use battery-operated smoke alarms, and we can’t emphasize enough the importance of upgrading these to help ensure families have working alarms in case of a home fire,” said Jon Pasqualone, executive director, Florida Fire Marshals and Inspectors Association. “By sealing the battery inside the alarm, the unit becomes tamper-resistant and removes the burden from consumers to remember to change batteries, which will save lives.” These smoke detectors use a 9 Volt removable battery. As pictured above, these detectors DO NOT have a Sealed Lithium-ion Battery that complies with FLORIDA Law. You might want to check your State and Local Laws for your requirements. http://www.kidde.com/home-safety/en/us/news/news-article/new_florida_law_will_help_save_lives.aspx

FireX Hardwired 120-Volt Inter-Connectable Ionization Smoke Alarm with Battery Backup (4-Pack) is rated 4.5 out of 5 by 199.

However, I have one criticism of something I found extremely frustrating and should be fixed. When I was searching on the Home Depot website I read the instruction manual that was posted along with this product. The online manual indicates that "lithium" batteries can be used for backup. I liked that because they last so long and was exactly what I wanted. However, after buying the products and reading the instructions enclosed with the alarms, it clearly says lithium batteries can NOT be used. I even went so far as to phone the manufacturer's customer service line where they confirmed that lithium batteries should not be used. How does such a discrepancy happen? Sloppy. Please fix.

The hardest part of the install was finding the breaker to the circuit that provided the electricity to the device(s). While I had to switch out the old base-plate for the new one as they were incompatible, I was able to reuse the old mounting screws since the new plate had multiple choices for the locations of the screws. It came with a "no name" 9V battery which I do not expect to last very long but the good news is that battery door is on the front of the device and makes for easy replacement. Overall I installed 4 of these and they each took about 10 minutes to switch out, after locating the correct breaker switch for the alarm.

I checked the manufactured date on all of my 6 Smoke Monitors and discovered that they were all well over 10 years old and needed replacement. Buying this 4 pack made the most $$ sense. I also purchased 2 Smoke/CO2 Monitors (one for each floor) to complete the total replacement project. If you do this type of project you will need basic electrical skills - remember to find and shut off the related electric circuit. You may have to remove and replace the updated base plates and wire harnesses. Assuming that the original wire harnesses used "wire-nuts" - the only tool that you should need is a screw driver.

After researching at Consumer Reports and reading a large number of reviews, both good and bad on this site, I decided to buy these. I had six to replace and it took me less than 30 minutes all together. Had to replace the wiring and mounting plate in the process too. Based on that easy, fast replacement process I will give these a five star rating. Time will tell if they generate false alarms and actually work.

I found it easy to install the new Kidde smoke alarms as a replacement for ten year old ones of the same brand. When the battery goes dead you can press the test button to stop them from chirping for 13 hours. It always seems the battery goes dead when you're trying to sleep so that feature will help.

Only 3 stars because you never know which box you're going to get with 1 bad one. I don't understand why not all of them will just work, but in a box or two there is just always one that will be manufactured or handling defect. That should be unacceptable.
