Smoke detectors - hardwiredOur house was built in '03 and has "built-in" smoke detectors (BRK 4120) that are AC-powered and wired together. A couple seem to be dying as they will beep for no obvious reason. Putting in a brand new battery makes no difference.
I found a model from KIDDE that includes different wiring adapters for this brand (multiple models, including ours) as well as First Alert models. My question is in regards to the mounting plate. A person at the big-box store (please, comments about the reliability of store staff aren't needed nor desired) said that for a number of years, these plates are supposed to be "universal" for exactly the situation I'm running into. Is that the case ? I have the KIDDE website open in another tap as I type this and will be reading up next... |

Many newer smoke detectors have this feature where they will start beeping when they are due for replacement (10 years). Your smoke detectors are doing exactly as the manufacturer intended. |

The mounting plate for the BRK 4120 is standard, that is to say it will match almost any box it is to be mounted to and all powered smoke detectors nowadays have bases included that will match the pattern of the box the BRK 4120 was mounted to as such they are "universal" |

I'm dealing with that exact same issue at my (aged) fathers house now. Lots of complaints on BRK equipment: » www.amazon.com/BRK-Brand ··· points=1His is dated 2007. |

I know that the "back" side, the side that mounts to the outlet box, would be standard. I'm referring to the visible side. It sounds like what you're saying is that the new detector will (may) in fact twist-and-mount into the BRK's mounting plate though.
Replacing the plate is certainly an option - my concern was it may be bigger (not as much of a problem) or smaller (more of a problem as worst case, drywall patching may be involved). |

Yeap, I read those already -- if my issue is truly an end-of-life warning, I shouldn't complain. Maybe some of the people complaining at Amazon shouldn't either.
I saw one person who "fixed" this by removing AC power and battery, holding a button in for "x" seconds, then re-connecting. I wonder if what they in fact did was reset the 10-year warning signal ??? |

I've been looking at this unit from Lowes: » www.lowes.com/pd_429793- ··· =4113870I bought my house in November 2012. It's 1985 construction and I bought it from a woman who was in her 90's. So, I have no idea how old the smoke detectors are, as everything else I asked her about ended up being wrong (because I think she just couldn't remember). So, I am going to replace the three units in my house because I have no clue as to their age. I pulled one down and couldn't see anything that would give me an indication. |

NFPA code says that interconnected detectors must be certified to be interoperate... And no manufacturer tests or approves their residential detectors with another companies products...
10 years is the recommended end of life for most smoke detectors...
Replace them all, at the same time, using a common brand (as in all the same) for the replacements... I like Kidde, personally; but that's just preference.
As for the mounting plates - in my experience, they aren't interchangeable between brands... Kidde detectors will generally fit on other Kidde plates, first alert on first alert; but haven't seen a Kidde fit a first alert, or vice versa... |

The manual for the Kidde model I looked at says it can be mixed with other compatible models. BRK lists interconnectible models here as well, » www.brkelectronics.com/p ··· ence.pdf |

First Alert sucks. Get a Firex (now owned by Kidde). I suggest you replace all of your smoke alarms with Kidde KN-COSM-IB combo smoke/CO 120V with battery backup. See » www.kidde.com/Documents/ ··· heet.pdfThere's also an equivalent battery powered one (no interconnect, of course). |

Ten years is the recommended replacement age for smoke detectors due to the small amount of radioactive material inside that actually makes it work. Studies have proven that after ten years the reliability of the detector falls of to a point that they should not be trusted to accurately detect smoke in the proper time frame. |

The 10 year 'lifespan' is not due to degradation of the radioactive element inside the detector. » www.epa.gov/radiation/so ··· arm.html |

Thanks for posting the link to accurate, factual information on the Radioactive material contained in a smoke detector. Electronic devices usually have a useful life of about 10 years and detectors would not be any different. |

First, thank you for starting this discussion. I am at a crossroads myself. I have about eight smoke and 3 heat alarms interconnected in my house. They are all about 11 years old so I'm thinking of replacing them.
In response to Booost, i looked into his recommendation and found this comment on Amazon:
"After purchasing 3 of these devices before selling house, I learned that they are unacceptable in the State of Massachusetts for the inspection. The Fire Chief in my town explained that only "photoelectric" type devices (First Alert or BRK) will qualify. I would check your local fire code (call your fire department) before spending money on the Kidde device. Unfortunately, we did not realize this and are now stuck with these devices.
After further research, I realized that this device states in its information brochure (which is NOT on their website description) that "it should not be installed within 3 feet of the door to a kitchen, door to a bathroom containing a shower, air supply duct use for heating ..." In our house that is basically where all the original hardwired smoke detectors are located when they were originally installed."
Not sure how accurate the above is. Bottom line, I'll be visiting the friendly folks at my Fire Department. When I installed these for the first time (on an existing house) they were very helpful and came to the house to recommend the proper location to minimize false alarms. |

All this discussion prompted me to pull down all three of the hardwired detectors in my house. The one I pulled previously didn't have a sticker with a date but the other two both have small stickers that read August 18, 2006. All three serial numbers are in sequence. So, I guess I am good until August 2016 as they are all the same age.
They are Kidde 1276E, which is a discontinued model. It's just a pretty basic ionization unit. After reading the posts in this thread it seems prudent to stick with Kidde/FireX when it comes time to replace them. |

There's also an equivalent battery powered one (no interconnect, of course). I'm actually going to do an AC and DC wireless jobbie. When I get some spare cash to replace 6 units and a CO unit - I want a wireless jobbie out in the garage to alarm the rest of the house when it goes off. And yes, I know. They don't recommend one in the garage and they can suck it. With the basic unit I have in the garage now, it never false alarms. |

In general, I think that the big-box stores, electrical supply houses, etc are either aware, or made aware, of things like that -- that is, they won't sell, or continue to sell, items that aren't allowed in either the county, state, etc.
And for the record, I'm okay with this (arbitrary) 10-year life span and am going to replace them. As noted in my OP, my primary question was related to how to replace them, not should I. |

Swapping out the pigtails and mounting plates isn't that difficult. About 7-1/2 minutes per. That includes dragging the ladder around. |

Kidde (Firex) makes a photocell model which is similar to the ionization unit I linked to. So get that one if you want.
Requiring photocell units seems dumb to me. I have ionization units next to the bathroom, next to the washing machine, and near a heating supply duct, and they all work fine. Zero false alarms.
The State of NJ inspects our smoke/CO detectors every 5 years. They're fine with the Kidde ionization ones we have. |

Ionization and Photocell detectors (obviously) work in different manners; and are better at detecting different kinds of fires.
Ionization detectors are better for free burning, hot fires; photocell/photo-electric detectors are better at smoldering fires...
There are combo units that do both; or install a mixture. |

Under the Canadian Fire Protection and Prevention Act; the FD does have the right to enter and check for compliance... That said - unless we've got complaints from By-Law or other agencies, we don't push the issue. Departments routinely to voluntary inspections (door to door; "Hi, we'd like to check your detectors, may we come in?" kind of thing) or check detectors while in the premise for other reasons (medical assistance calls, etc). I'm not sure how the US laws are setup, though. |

What citizen rights, your right to die in a fire?
I wish fire departments did inspections here in Iowa, lots of people die every year because smoke detectors either were not working or missing completely. |

You may want government intrusion but the majority of Americans would not agree. What's to keep them from "inspecting" other things? Nothing. Once it starts there are no limits.
Maintaining smoke detectors is the responsible thing to do but it's not up to government to force their way into homes without a search warrant detailing probable cause to "inspect". |
