Customer 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?
Asked by: Howard
No they do not. The ten year law requires a smoked detector with a sealed lithium-ion battery. However check with you state and local laws because these are not required in every state and some places not every application.

Eleven year old Firex model 5000, can I replace by just plug in ?
Asked by: ZXC
Hello ZXC. You will have to take down all of the old alarms before you put up any new alarms and you will have to change out and rewire the wiring harness plugs or use the adapters and you will have to change out the brackets. To keep from having to change out the wiring harness plug, let me recommend the 21009444 which comes with alarms and wiring harness adapters. You plug the adapters into the old plugs and plug the new alarms into the adapters. You still have to change out the mounting bracket but that just takes a screwdriver. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

FireX Hardwired 120-Volt Inter-Connectable Ionization Smoke Alarm with Battery Backup (4-Pack) is rated 4.5 out of 5 by 168.

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.

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.

Replaced troublesome First Alert alarms with these, and so far no false alarms. Even though package says they are not compatible with products from other manufacturers, I still have one First Alert wired and it works just fine with the FireX. If you are comfortable using wire nuts there is no need to buy the optional conversion plug adapters; just disconnect the old one at the wire nuts and connect the new alarm using the same nuts. Removing the old mounting plate first allows easier access to the wiring.

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.

Rated 5 out of 5 by from Hush Button and Protection Also As a handyman for many years I have sold and installed over 1000 of this model and besides it's reliability the thing that sells it is the hush button. No more late night calls since I always make the end users aware of the hush button and what it does. Lets you sleep when you forget to change your battery by pressing the hush button with a broom stick. Easy to change batteries without taking down the unit

Even though they changed the connector geometry (why, please?) the supplied new connectors wire in easily enough. And batteries included is a very nice touch. Works as advertised, which I have come to appreciate greatly in this new house of mine!

Used these for years in new home construction and just put in my home to replace the aging detectors. I looked at other home stores and didn't like their selection - thanks Home Depot for stocking. Easy installation, smart design, they just work
