The updated Kidde Firex KF10 and KF10R alarms are mains powered, interlinking ionisation smoke alarms that use up to 70% less energy than previous Firex models. The units are hard wired and can be interlinked with other units from the series to create all round fire protection within the home.
Please note: The Kidde Firex KF10 (previously KF1 / 4870 / 1240C) and KF10R (previously KF1R / 4881 / IAR230C) are replacements for the Kidde 123/9HI, 123/9HILL and 1275H series and can be electrically interlinked. However, the new models cannot be used on the old base plates for the 123/9HI, 123/9HILL and 1275H series as they use different style connector blocks. This means that base plates must be swapped over on those stated models and connectors need to be replaced.
The table below shows all the units that can interlink with the KEKF10 and KEKF10R.

Thankfully Compatible I inherited a house with old 323/9HILL and 123/9HI alarms, which I had to partially replace. Although both of these are officially obsolete, the KF10 is fortunately compatible with the synchronisation circuit that connects them all. Sadly, the physical connection is different, so you need the new (ceiling) baseplate, and the connector design is also less elegant, as it takes up far too much space where the cables need to go (i.e. it's a vertical rather than the horizontal fit of the older models). It certainly works (very loud, although a bit too sensitive for my liking) and the LEDs are a bit bright, but they're OK.

Product as described. However, I had to wait about four weeks for this item to arrive which meant that my son was unable to fit the alarms before he went back to England. Disappointed I was not informed that delivery would not take place until all items could be delivered together.

Easy to install. Easy to test. Manual and instructions are very clear. Difficult to test the interlink though.
