Hardwired Smoke and Combination Detector Adapters

A:  Hello. What kind of cable is unfortunately vague. Our hardwired smoke and carbon monoxide alarms should be installed on a UL Listed or recognized junction box. All connections should be made by a qualified electrician and all wiring used shall be in accordance with articles 210 and 300.3(B) of the U.S. National Electrical Code ANSI/NFPA 70, NFPA 72 and/or any other codes having jurisdiction in your area. The multiple station interconnect wiring to the alarms must be run in the same raceway or cable as the AC power wiring. In addition, the resistance of the interconnect wiring shall be a maximum of 10 ohms.  The maximum wire run distance between the first and last unit in an interconnected system is 1000 feet. See owner's manual for the wiring diagram. Our hardwired units connect to the house wiring with a wire harness plug with 3 wires. If you are replacing older FireX AD, ADC, FADC, FADCQ, FADCM, or PAD smoke alarms with current Kidde alarms, you can use the KA-F2 adaptor, one of the two adaptors in this pack, to keep from having to rewire. You can plug the adaptor into the wiring harness for the old alarm and the new alarm will plug into the adaptor. If you are replacing the older BRK or First Alert models SA4121B, 4120, 4919, 5919, or the 86RAC with the current Kidde alarms, you can use the KA-B2, the other of the two adaptors in this pack, to keep from having to rewire. Like the KA-F2, you can plug the KA-B2 into the old wiring harness plugs and plug our current alarms into the adaptor.

A:  Hello. This is not an alarm and does not have a battery. This is a set of two different types of wiring harness plug adaptors. If you are replacing older FireX AD, ADC, FADC, FADCQ, FADCM, or PAD smoke alarms with current Kidde alarms, you can use the KA-F2 adaptor, one of the two adaptors in this pack, to keep from having to rewire. You can plug the adaptor into the wiring harness for the old alarm and the new alarm will plug into the adaptor. If you are replacing the older BRK or First Alert models SA4121B, 4120, 4919, 5919, or the 86RAC with the current Kidde alarms, you can use the KA-B2, the other of the two adaptors in this pack, to keep from having to rewire. Like the KA-F2, you can plug the KA-B2 into the old wiring harness plugs and plug our current alarms into the adaptor.

A:  There is no direct replacement for your alarms. That being said, you can use any of our current alarms to replace your older alarms. You will have to take down all of the older alarms before putting up any new alarms. You will have to change out the mounting brackets at each location but that will just take a screwdriver to change out. You will either have to change out and rewire the wiring harness plugs at each location or you can choose to use the KA-F2 adaptors to adapt the old plugs to our new alarms. The adaptors would plug into the old plugs and the new alarms would plug into the adaptors. The model for the adaptor pack is the 21028461 which includes the KA-F2 and the KA-B2 for some of the older BRK/First Alert plugs.
