What are the requirements for a smoke detector in a rented apartment? or rental house? someone told me it had to be a 10 yr battery warranty.
Asked by: Mary
I think your landlord would be responsible for the alarms. It would be to your advantage to check the existing smoke alarms for the date of issue. If it is over 10 years the radioactive element in the alarm is no good and it needs to be replaced. I installed the 10 year sealed battery alarms in my house along with a carbon monoxide combo alarm for one of the units near the kitchen. Also check to make sure there are chemical fire extinguishers installed OUT of the kitchen at about 3 ft off the floor and one near the bedroom. Have your landlord replace the fire extinguisher unit(s) every year. These small measures will save your life if a fire occures because every second counts and if you have a working alarm and extinguisher if could save your life!

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
I would contact the manufacturer with model number. They will tell you the definitive answer.

Worry Free 120-Volt Hardwired Inter-Connectable Smoke Alarm with 10-Year Battery Backup is rated 4.4 out of 5 by 209.
Rated 1 out of 5 by from My original plan was to have a great replacement that would not need 9V battery replacements for ... My original plan was to have a great replacement that would not need 9V battery replacements for 10 years, so I went all in with 5 of these units. Less than 12 months later I am getting full blow false alarms in the middle of the night terrorizing my young children. To make matters worse with the interconnected system in my house, the whole place starts chirping yelling "fire fire," when my house is completely fine. I cannot go to bed comfortably anymore without the fear of yet again another false alarm at 2:00am. This is by far the worst home improvement product I have ever purchased. Home Depot should not carry this horrible product.

No more changing 9V batteries. We installed 8 new units through out the house about a year ago. Today, the third unit failed. It isn't the annoying little chirp either. It is the full blown alarm going off at 2:00AM every couple of weeks. I'll be installing a different brand today.

Installation was easy, price and features (10-Year battery backup!) were great. One big problem: the green LED on these things is *WAY* brighter than the old Firex alarms I replaced. Covering the LED didn't help--there was still a dinner-plate sized green glow emanating from the sides that was bright enough to disturb our sleep. I wound up popping the things apart and covering the LED lens with a big glob of black craft paint. This voids the warranty, but there really aren't any good alternatives for a wired alarm with 10-year battery backup--the equivalent 1st alert has the same problem.

I had an electrician install my new smoke detectors, so it was easy for him. I love having the 10-year lithium batteries because our detectors are located about 12 feet up on our cathedral ceilings. Now I won't have to worry about getting up there and changing the batteries every 6 months. The white color of the alarms look much better against our white ceilings, rather than the yellowish color of the old ones.

If you love being awakened with false alarms at 2 a.m., this is the alarm to install! I bought eight (8) of these, with the idea that I wouldn't have to change batteries once a year and perhaps save some money. The reality is that after 3 months of installation, I have had 3 false alarms on 3 different devices. My research elsewhere now discloses that this is a characteristic of this alarm, as they are very sensitive to dust, insects, etc., all of which will trigger a false alarm. The company's suggestion to cure this? Use compressed air monthly to clean the units. So much for convenience and cost savings. Don't waste your money.

I bought 4 total, 3 of which are on the same electric line. When I installed the 2nd and 3rd one, it gave me confirmation that they were all working in tandem. I thought the 4th was on the same line, so I hooked it up that way, but it kept beeping periodically so I knew it was not on the same line. Just disconnected the red wire and it was and has been fine ever since. Kidde customer service is clueless just in case you have to call them.

I recently (October 2017) installed a bunch of these alarms to replace old ones that expired. I don't know how well the new alarms will work and if they will last ten years, as they are supposed to. I gave the alarms a 5-star rating based solely on the installation, which was simple. The new alarms were very compatible with my old alarms, so I didn't have to change the mounting holes or the wiring. I expect these lithium battery alarms to be cheaper in the long run than 9-volt battery alarms.
