will the adapters work with firex 120-1079 smoke alarm made in 2006.
Asked by: sparky
Hello Sparky. No. The wiring harness adaptors will not work with your wiring harnesses. You will need to take down all of your old alarms before you put up any new alarms and you will need to change out all of the plugs and brackets at each location. The safest way to do this is to get a licensed electrician. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

I have a set of 4 Firex smoke alarms (model # 120-538, the best I can tell). One went bad, and I need to replace the whole set, since they are about 20 years old. Which Kidde/Firex interconnectable models will be the best replacements?
Asked by: Dan
Hello Dan. The sku model of 21009444 comes with the I12060 smoke alarm AND the adaptors and this alarm will work the adaptors. It is available as a single alarm as Internet #100246185, Store SKU #445228, or as a 4-pack as Internet #203119550. Nearly any other of our hardwired smoke alarms will work to replace your alarms, and the adaptors will keep you from having to change the plug. The adaptors will not work with the I12010S (21010407-A), the I12010SCO (21010408-N), and the KN-COSM-IBA (21006377-N). These models will not work with the much older wiring harnesses because these particular alarms won't fit onto their brackets with the adaptors. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

I have a 2005 Firex 120-1693 that needs to be replaced. Is this adapter compatible with the model I have? The documentation seems to suggest no, but from the pictures, I think it should work. Thank you.
Asked by: SEH
Hello SEH. No, the adaptors will not work. You will need to take down all of the old alarms before you put up any new alarms, if your alarms are interconnected, and you will have to change out the wiring harness plugs and mounting bracket rings at each location. If you are not familiar working with wiring or have any questions about wiring, the safest way to replace the alarms is to get a licensed electrician. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

I have 6 existing FireX 120-1072C smoke alarms. Interconnected w/ battery back up. I see from a previous question/answer that the adapter will work with my existing wiring and plugs, however will I need to get a special mounting bracket to hold the adapters or will the bracket for the new detector have enough space to accommodate the adapters?
Asked by: KarenF
Hello KarenF. The new alarms will come with new mounting bracket rings. Changing out the brackets only involves using a screwdriver and you don't have to drill new holes. The bracket will allow for the adaptor in all of our hardwired alarms EXCEPT for the I12010S (21010407-A), the I12010SCO (21010408-N), and the KN-COSM-IBA (21006377-N). Any of our other alarms can be used with the adaptors. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Smoke Alarm Adapters is rated 3.7 out of 5 by 18.
Rated 5 out of 5 by from These adapters eliminate the need for any wiring work when replacing A-C powered smoke detectors,... These adapters eliminate the need for any wiring work when replacing A-C powered smoke detectors, They are compact, taking up little room in the electrical box. They fit well and are easy to use. Snap the correct adapter onto the new detector, then snap in the wiring connector that connected the old detector. If you are comfortable with wiring work, you don't need these, otherwise, they make the job very easy.

The plastic circle around the adapter was too big, which meant I could not attach the smoke alarm to the mounting plate. Poorly designed, very frustrating. Had to rewire the socket after all.

Rated 1 out of 5 by from Did not fit connector I was told at the store that the connectors would allow me to use my old cable harness with the new detector but it did not match the cable harness and thus could not be used .
