Direct replacement for Firex with included adapter

My Firex units timed out in our 11 year old house. All 5 started chirping within a few months of each other. These units at Wal-mart were almost direct replacements. I used the included adapter so my old wiring plugged into the new units. The only thing I had to do was remove the old base plate and install the new one (a 5 minute job with just a screw driver). I did have to find some A/C wired CO detectors at a different retailer, but it all worked out.

Would buy again from ZORO

These were replacements for two existing alarms in our home. Could not stop these two from chirping. Pigtails and new connection included. A very simple change. ZORO had a very good price and delivery was fast.

I bought these to replace FireX model #120-1182b. The new one comes with the necessary pigtails to hardwire them (the connection to the unit is different from the previous model that I had).

This is a simple replacement for the original / identical unit that lasted 15 years. I like sticking with a company with products that work.

1. Hello Chuck, Firex became part of Kidde in 2008. Their product was discontinued. The new units, which are Kidde, have a different wiring harness and mounting bracket that will need to be installed. Because they are not compatible, all of the old units must be removed prior to installing the new. Thank you for choosing Kidde.
