The Kidde KN-COSM-IBA 900-0114 Combination Carbon Monoxide and Smoke Alarm provides two important safety devices in a single unit. This Kidde alarm includes a voice warning system that announces "Fire, Carbon Monoxide, Low Battery or Smart HushTM Activation". The voice alarm eliminates any confusion and clearly warns you and your family of a smoke or carbon monoxide danger, or if your battery is in need of replacement. This technically advanced combination alarm includes 9 volts battery backup providing protection even during a power outage when many incidences occur. The Kidde KN-COSM-IB is an easy to install alarm that is suitable for all living areas and has a 5 year limited warranty.

Please Note: The Kidde Alarm KN-COSM-IBA (900-0114) replaces Firex 12000.

Need to replace old Firex alarm?

Please Note: Unless you are replacing Firex FADC, ADC, and AD, you are REQUIRED to replace ALL your old Firex alarms with this KN-COSM-IB unit. Otherwise, your old Firex units will NOT be able to communicate with this KN-COSM-IB unit. This Kidde KN-COSM-IB model can replace the old CO & smoke Firex model:

Firex 12000 - Firex FADCQ 7000

Since old Firex and new replacement have different wiring harness, the existing wiring harness needs to be changed.

If you don't want to rewire, you need to get a quick convert adapter Kidde KA-F and perform 3-easy-step installation:
1.Replace the ceiling mounting bracket
2.Install KA-F adapter and attach existing wiring to the alarm.
3.The new alarm will now be interconnected and compatible with your Firex alarm system.
