Manufactured with photoelectric sensors for detecting smoke and fire, this alarm also includes the world's most accurate CO sensing technology based on claims by major manufacturers.

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-COPE-i unit. Otherwise, your old Firex units will NOT be able to communicate with this KN-COPE-i unit.

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.
