Asked by: Shumpy
3 wires. The white wire just got stuck back into the box, not needed. Was perfect.

Yes, it does a different mounting plate, but only takes a minute to replace. I replace all 7 of mine in less than a hour.

What does it mean when the detector alarms out of nowhere, for no reason?

It sounded one time and has been quiet since.
Asked by: Cal4
Check it by depressing the button. If it doesnt go off you need to evaluate putting a new one in. Sometimes dust gets clogged inside. Blow air w/hair dryer on it. Replace battery. Try again. If no response, replace.

Possibly but the new bracket that the product comes with is very simple to put in place. I managed no problem. Enough said...

FireX Hardwired 120-Volt Inter-Connectable Smoke Alarm with Battery Backup is rated 4.1 out of 5 by 152.
Rated 1 out of 5 by from NUISANCE ALARM NIGHTMARE Replaced all smoke detectors in the common areas and bedrooms of my apartment building with these detectors replacing BRK detectors. Also where applicable for compliance, I replaced the CO detectors with Kidde combo CO/Smoke detectors... and they have not been a problem... But these smoke detectors (Item 21006371 / Kidde Model p12049) are ansolute junk!! Really dont think that these other reviewers have had them in long enough! They are a nuisance alarm nightmare and I have now replaced all 9 that I installed woth a product that works! If ypu are a landlord looking to prevent tenants from disconnecting your smoke detectors or from having to pay an electrician to replace them (again), do not buy this product as it is defective! And just so everyone knows, my apartments are clean and smoke free and no longer nuisance alarm since getting rid of these garbage smoke detectors.

Rated 1 out of 5 by from This is not worth it These smoke alarms have false alarms and Kidde customer service is basically non existent. You wait 20-30 minutes, customer service is rude. So return them to Home Depot and look for First Alert products

Only 4 of the 6 worked out of the box. The other two either chirped incessantly or went off randomly. The instructions are very specific about the exact brand of battery that must be used, but they supply their own generic battery with the unit.

Other than that no issues. Just check the boxes before buying them. People will take what they need out of the box and when you get it home your missing the battery or the plug in

I was replacing an 5 older model Kiddie smoke detectors and these were extremely easy to install and had no problems at all. Kinda wish the old Kiddie smoke detectors lasted longer than 5 years but I can’t bring this ones rating down because of an older model. Great and simple to install.

Smoke detector was a replacement for an older one and was very simple to install- took no more than 5 minutes. Initial concern was about the flashing red light but it seemed to settle once hardwire and battery equilibrated. Bought two and am keeping the second as a spare.

Rated 2 out of 5 by from Seems fine except the unit twists clockwise to remove it... Seems fine except the unit twists clockwise to remove it from the base, counter-clockwise to attach. That is obviously backwards. I now have a lone alarm unit that works opposite to the rest. An annual irritation every time I replace batteries.
