Review on 🔌 Kidde KA-F Quick Convert Adapter for Firex Wiring Harness - 6 Pack, Facilitating Kidde Alarm Installation by Earl Ton

If you have old Kidde smoke detectors with a straight 3-pin plug, you can use this adapter to install new Kidde Firex detectors with a triangular 3-pin plug. Install pin connector -pin connector without rewiring. Of course, these adapters simplify and speed up the installation of replacement smoke alarms. However, new Firex detectors come with a new pigtail connector, so it's fairly easy to unscrew the nuts from the old pigtail connector and then screw the nuts onto the new pigtail. Given the low price of Firex detectors, these adapters seem a bit overpriced and aren't required unless you really want to do the wiring.
