I looked on-line to see how well First Alert was rated and it looked like one of the top choices. My old yellow-tinged fire alarm units were made by a different maker and lasted nearly 20 years before they began to sing in unison when only one went off. Running around at the wee hours did nothing for us but more loss of sleep. Usually a 9 volt battery would remedy the scenario, but not this time. We had to temporarily disconnect each screaming unit and go back to bed. the next day after some research found that all units should be replaced after so many years. First Alert was our choice and these unit came with the necessary wire attachments to work with the alarm receptacles. They fit perfectly onto the electric boxes and we used the existing wire nuts to make the initial 3-wire connections. 5 stars !!! Thanks.Read full review

It's a direct replacement for my existing units. Installation was easy. Battery was included. Plugs were included in case i needed them (I didn't). Even a hair net type was included to protect the unit during construction. No problems so far with any of the units I received.

As described on the product page the First Alert BRK 9120 was a direct replacement for my original First Alert smoke alarms. I purchased the 5-pack after one of my detectors went bad. I wanted to replace all detectors at the same time to avoid not knowing which detectors were replaced. The BRK 9120 installation was simple. The base easily replaced the original using the same screws. Used the original wiring as well. Before replacing all original detectors I tested the BRK 9120 and it worked with my original set of detectors. I highly recommend the product.

Perfect Fit Replacement for my entire house Alert system. My older units were chirping and triggering an alarm due to age. I simply replaced whole system with contractors pack of 6 replacements. With minimal re-installation of baseplates and 15 minutes of time my house is protected and false alarms are history. Great item.
