I'm giving this one star solely because of the date of the model received (July 10, 2013) is almost a year old already when put in service new.
I used the Quick Connect Adapter (KA-B and KA-F) to replace existing mixed alarm system. As expected, once all ten ion, photoelectric and co detectors were Kidde branded the interconnected alarm feature worked. As an added feature the Kidde KN-COP-IC CO detector displays "Fire" during test. Although you do not need the Adapters if you don't mind rewiring I decided to purchase six of these as I could rewire 8 alarms (2 BRK 5919, 6 Firex various) more quickly and personally decided the approximately $25 cost was worth the time saving as some of these alarms were placed on both high and cathedral ceilings -- your mileage will vary. Two of the existing alarms were less than 10 years old and did not need to be replaced (i12040, 1275) and these as expected worked with the new CO detector, plus 3 P12040 and 4 i4618 smoke detectors.
