We replaced nine smoke detectors with this model in our home. One beeps about every 30 seconds. Is it a bad unit?

Tried flipping the breaker but did not help.
Asked by: MO
Possibly. You could try putting a fresh battery in it and see if that helps.

I live in a 12 year old condo with 5 hard wired smoke alarms w/9 volt battery backup I periodically replace the batteries. Do these devices wear out over time and do I need to replace my existing alarms?
Asked by: Poppop
Hello Poppop. The smoke alarms should be replaced every 10 years per the recommendation of the National Fire Protection Agency. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Worry Free 120-Volt Hardwired Inter-Connectable Smoke Alarm with 10-Year Battery Backup is rated 4.4 out of 5 by 99.
Rated 1 out of 5 by from Very disapointed I purchased this smoke detector to replace a Kidde detector that was roughly 5 years old. The previous detector began to chirp frequently and would not hush with the battery replaced and 120VAC confirmed . The latest Kidde detector began to chirp and not hush two months after installation. At same time another Kidde detector (basement) installed during the same time frame began to chirp (battery was replaced twice). The solution was replace the Kidde detectors with two "First Alert" detectors.

Rated 3 out of 5 by from Decent product We replaced most of our detectors and after many frustrating nights of the alarms going off intermittently, we discovered that all of the units including the heat detector in our garage needed to be Kidde brand as well. They will not work with other kinds of detectors. Mine were first alert and had to replace those as well even though they were only 2 months old. Keep that in mind when buying. Good detector, just not compatible with other brands.

Rated 4 out of 5 by from Easy Peasy I bought these to replace the 10 yr old units in my house. The wiring was already in place. Just took out the old units, replaced the bracket, hooked up the wires and locked the new unit in place. I would have given it 5 stars, but the green LED is so bright it illuminates back up though the case and radiates off the ceiling. Much brighter at night than my old firex units. All in all seems to be working fine.

Appears to be working fine and I really like that I don't have to replace the battery. The only annoying thing is that the closest Home Depot does not carry these, but all the other ones in the area appear to. Tip: there's a tab on the exterior of the unit that you need to press to remove it from the base.

Put this detector in the places that are a pain to access for battery changes, like high ceilings. Keep in mind that you'll have to wire a new pigtail if the old one won't fit your new alarm. Get a qualified person to do the installation if you're uncertain or uncomfortable with electrical wiring.

We purchased these smoke detectors after the original ones that came with the house reached their expiration date and would chirp incessantly, reminding us that their end was near. Installation is a breeze. If you can remove two screws, twist together and cap three wires, replace two screws, and twist an objection in a circular motion, you are capable of installing these smoke alarms. We had to replace eight of them and by the second one, I could have them up and running in minutes. In terms of functionality, they are fantastic. The sealed battery was the best decision we made, even if it was a little more expensive up front. No more chirping! The decibel level is noticeably louder, which I don't see as a fault. I like being alerted to a possible fire. If I had to leave one complaint, it is that the AC power light is a little obnoxious. It gives the unit a slight green glow, which can be annoying in the bedroom but we got used to it. It's like getting a free night light!

I would guess that most people only review this smoke alarm if they have issues so after a month of having two installed I am happy to say that these are great. No false alarms. Easy to wire in myself. Trusted company. 5/5 would recommend.

Luckily we have not had to put it to a "test" (with a fire in our home!) but it seems an able replacement for our outdated, obsolete smoke alarms. Size fit previous model with no problem with ceiling paint. Just installed January 2017.
