Interconnected smoke detectors - no circuit breaker?
Home built in 2005. These are interconnected Fireex smoke detectors (I believe because they have a yellow wire connected to the red wire). All the breakers are marked, but I don't see one for the smoke alarms.
Now I was away on business and my wife had an alarm chirping and couldn't get it to stop so she literally in wired it while it was hot! Could have killed herself. Problem is I want to rewire it and I don't know how to cut the power to it since there is no breaker. Thoughts? |

It will likely be shared with another circuit - in USA the code required the smoke detectors to be on AFCI breakers, I believe.they are GENERALLY connected to a bedroom circuit - which also requires AFCI protection.. This is NOT a code requirement but is acceptable best practice.. |

Interconnected smoke detectors - no circuit breaker?
The smoke detectors are most likely connected to a breaker that won't normally be turned off by a homeowner. Typically it is wired to the furnace circuit. Open up the panel, it should be the only breaker with 2 hot wires connected to the breaker.
Note: items like furnaces have service switches at the unit to prevent anyone from powering up the device without the service personnel knowing about it. This is true for remote AC units as well. Dan |

Open up the panel, it should be the only breaker with 2 hot wires connected to the breaker. Maybe, assuming the breaker is rated for double tapping. I've seen quite a few homes here in NJ with hardwired smoke detectors both old and new construction, none had double tapped breakers on anything. |

Problem is I want to rewire it and I don't know how to cut the power to it since there is no breaker. Thoughts? In my state the smoke alarms cannot be on their own circuit breaker. They must be connected to a receptacle or lighting circuit. This is so people do not shut off the smoke alarms due to false alarms and have no protection as a result. In my state the smoke alarms are also required to have a battery backup in case the power goes out or the circuit breaker trips. Using a non-contact voltage tester (This is what I use: http://tinyurl.com/FlukeTester ) you can safely test the circuit by flipping the circuit breakers off one at a time. If the smoke alarms are interconnected they will only be on one circuit. Smoke alarms are generally rated for 10 years of service, so yours should be replaced. I suggest that you also buy some better batteries as the ones that come with the new alarms are not long lasting. Home Depot sells long life lithium batteries that may last as long as the smoke alarm depending on use. John Grabowski https://www.MrElectrician.TV |

That the code doesn't specifically say that smoke detectors must be on an AFCI, only that the outlets in certain locations must be and that it's when a smoke detector is in one of those areas that it becomes covered, just like a receptacle would. What you cite is current code, which again, I said results in smoke detectors being on AFCI by virtue of where they are located because now bedrooms and hallways are required to have AFCI. BUT, the poster's home was built in 2005. And I believe back then, AFCI was not required in hallways, only in bedrooms. So, I believe his home could have smoke detectors in hallways outside a bedroom on a non-AFCI circuit and it could have been code compliant then and it's still grandfathered today. |

If you have an arc somewhere and it trips the breaker, hope it kills the circuit before starting a fire. And there's no other source of ignition (smoking, unattended cooking, etc.) that burns the house down while the smoke detectors are inactive. |

I think you'll find whether a hardwired smoke detector needs to have battery backup or not varies from state to state. IMO, it's overkill and a nuisance. A friend here has a new home and it has about 10 of them that start beeping for a new battery within a year. Why that is, IDK. You would think the battery is only there for backup and hence would last close to the shelf life, but they don't. Every fire death I can recall in the news, it was not the result of AC power being lost to alarms that were working. The typical scenario is no smoke alarms, smoke alarms removed, smoke alarm broken, smoke alarm with a dead battery, etc. My house has AC only alarms and that's what I prefer. |

The problem is if you have a permit for anything related to a sleeping space, you will be coming up to that code. You are actually dealing with multiple codes too. You have the life safety portion of the building code (NFPA 72/NFPA 101) and the electric code. These days most states are using a model code like the ICC to write theirs (driven by insurance companies) so things like smoke detector placement and requirements tend to be the same across the country. If your insurance company is not looking, older homes may not comply to any of this but those people are becoming more intrusive, particularly if you are changing companies. |

Now you need a smoke in each sleeping room, one outside the sleeping rooms and at least one on every other floor. This will be triggered if a permit is pulled for any other renovation and the only exceptions are if you can't do it any other way but opening up drywall you were not going to be in anyway. This is defined in ICC building code R.314 which is derived from NFPA 72. These codes tend to be adopted by states as their own. |

Which solves the problem Doug is talking about, ie whether one inside the bedroom or one just outside, may miss early detection. Given how many fires start from smoking in bed, requiring one inside the bedroom seems like a very good idea to me. And like you say, the interconnection is a big plus, a fire starting in the basement you'd get alerted long before smoke reaches a second floor bedroom. Still, from casual observation of the news, it seems that probably 95%+ of the protection comes from just having a working, unconnected alarm near or inside a bedroom. All the fatal fires I can recall reading about, there were either no smoke detectors, broken ones, disconnected ones, dead batteries, etc. But getting an early warning from interconnected alarms, multiple alarms, etc can also lessen the fire damage or avoid an actual fire, by getting to whatever is going on before it's too late. |

What do you mean by 2 hot wires? He means two wires connected to one circuit breaker. But this is mostly wrong. Most circuit breakers aren't rated for having two wires connected. And AFAIK you could also have the smoke alarms connected to whatever breaker by just wiring them into the circuit, AFAIK it doesn't have to be done at the breaker. What is your actual problem or issue? Two red wires? Connected to the breaker switch? First time homeowner, forgive me for needing more simplified instructions. I only recall seeing black switches, not wires in the breaker box. The wires are visible once you remove the panel cover. But if you're not familiar with panels, I would not suggest removing the cover or at least look at some online videos first. It's simple, but you want to make sure after it's loose you pull it straight off. You don't want to be holding it and have the top corner dip inside and contact the live service conductors. -- for full context, visit https://www.homeownershub.com/mainte...r-1127388-.htm |

Interconnected smoke detectors - no circuit breaker?
I've tried every circuit breaker in the house except.for the master and the smoke detector has remained hot. I suspect that my smoke detectors are wired together but supplied by two different circuits so that they will go off together. I'm simply going to cut power to the whole house to change the hard wired units rather than try to solve a very complicated puzzle.

They usually have battery backup. If they really are being fed from 2 circuits, fix that first or you might be needing those smoke alarms. |

They usually have battery backup. If they really are being fed from 2 circuits, fix that first or you might be needing those smoke alarms. If they really are supplied by two circuits, it would be easy to prove it. Just turn off all breakers and the smoke detectors would lose power. Then turn them on one at a time until finding one breaker where they have power again. Turn that breaker off and proceed to try all the remaining breakers. Also IDK why he didn't just open the main breaker, that would have proven whether they are battery backed up and that was what was going on. |

I guess 'double tapping' a breaker means that that breaker was originally designed as a two pole breaker for two ungrounded conductors of different phases. |
