About the Kidde i4618 Firex Ionization Smoke Alarm with LED Indicator
The Kidde i4618 Firex smoke alarm is chock full of features and protections. The ionization 120V AC alarm with a backup battery is compatible for use with both single and multiple stations, with the 15-minute False Alarm Control element that will silence an alarm, if needed.
This product also includes a front-loading door for the battery, a test switch, a dual-purpose LED indicator and an 85-decibel horn. A constant green on the LED indicator allows the user to know if there is AC power available for use, with flashing red that displays the alarm and battery status. And, due to its innovative PowerLink tab, the Kidde i4618 is shipped to customers with the battery installed and ready to go.

I am a bit confused. It seems Kidde makes many detectors that will replace my FireX adc unit. May I assume that they will all work, but the differance will be battery location, warrenty, size etc?

Are there units I can buy to replace Firex model G-18 without having to replace the wiring and bracket too?
No, there are no compatible replacements to Firex items that will not require a new bracket / wiring harness
All of our Smoke Detectors are firex 120-1072B, is this the replacement and how will it wire? Jim
Yes, this is the replacement for your old smoke detectors. They will come with a wiring harness adapter and new mount bracket. Simply remove the old unit and mounting bracket, install the new mounting bracket, and attached the wiring harness to your previous connection.
