Hardwired Smoke Alarms


Our home was remodled before we bought it and they shrunk the kitchen and extended the mater bedroom. Long story short I have (2) smoke alarms in my master bedroom and they are only about 7 feet apart from eachother. Can I just unplug it and patch the hole in the ceiling, and leave the wires as is in the attic space? I am just worried if I unplug it, it may effect the rest of the system somehow.

Thanks!

Are both smoke alarms part of the same system?

I've seen houses where a central alarm system included smoke detectors, and those were different from the normal stand-alone battery/electric units commonly installed in houses today. Local codes required the hard-wired battery-electric units, even if there was a central alarm system installed.

IF you remove either of them, and there is wiring present in the box, then you will have to install a blank plate to ensure accessibility later on. You can't just patch over a junction box, unless all the wiring is disconnect or removed first.

My plan was to flip the junction box unside down and attach to a joist and then cap it off, and then fill in the hole. That way everything is still accessible.

Also this is not an alarm system it is just a hard wired smoke alarm with battery backup. They are all hooked up together so if one goes off they all go off.

As long as they are both smokes only, & one is not a CO or combo smoke/CO then you should be OK
Only 1 required in a bedroom

Flipping the j-box up into an unfinished attic, where it would be accessible is a viable option.

I see no problem with that solution.
