Do these adapters accept a three prong triangular connector on one side and a three prong in line connector on the other side?
Asked by: Dale
Hello Dale. There are a number of companies out there that have 3 prongs in a line on the wiring harness connector. These two adaptors are for two very specific wiring harnesses. The KA-B adaptor is to adapt ONE of the specific wiring harnesses that used to be used by BRK for the use with Kidde Products. That would be the BRK wiring harness used with the First Alert models SA4120B SA4121B, SA4919 and BRK MODELS 4120, 4120B, 4120SB, 4919, 5919, 86RAC. The KA-F adaptor is to adapt ONE of the specific wiring harnesses that used to be used by FireX before we at Kidde bought them out, for the use with Kidde Products. This would be the FireX wiring harness used with the FireX Models AD 4418 , ADC 4518, and FADC both the 4618 and the 5000. These 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 adaptors because these particular alarms won't fit onto their brackets with the adaptors plugged in. We are Kidde Product Support at 1-800-880-6788. Thank you for your interest.

Asked by: Dale
Hello Dale. Yes, this adaptor will allow you to adapt the WIRING HARNESS to use it to install one of the current Kidde Products, except for the I12010S (21010407-A), the I12010SCO (21010408-N), and the KN-COSM-IBA(21006377-N). These models will not work with the adaptors because these particular alarms won't fit onto their brackets with the adaptors plugged in. You will still have to take down ALL of the older alarms before you put up any new alarms. The new alarms and the old alarms will not work together. You will still have to change out the bracket. This just takes a screwdriver and you don't have to drill new holes. But the adaptor will keep you from having to change out the plug. We are Kidde Product Suppor at 1-800-880-6788. Thank you for your interest.

I have four - 120-1182 that were installed 01/2004. One is defective and I was going to replace them with the i4618. Will this adapter work, to change the inline pins in the existing wiring to the offset pins on the i4618?

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.

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 .
