Very happy.

Would Recommend

These were the recommended replacements for our old smoke detectors per the First Alert website. Electrical connector and mounting plate synced right up. Couldn’t have been easier.

Had to do some wiring connector modification

Would Recommend

Once I modified the supplied wiring adapter, everything installed and worked just fine. My original detector wiring connectors from 1998 refused to fit the new supplied connector. By cutting off a piece of the new connector, it worked. I recently replaced detectors that had been installed in 2002, and they fit fine - so the minor change in design happened between 1998 and 2002.

Smoke alarms may not last 10 years.

This product was a direct replacement. The unit had a date stamp on it and as often as I kept seeing that they last 10 years, well the don’t.

It is only good for ten years

Would Recommend

It's interesting that something inside of the unit "expires" and requires that the whole thing be replaced in 10 years.

Easy to replace with different model

Fairly easy to replace prior interconnected smoke detector. Connector format appears to be standard for different manufacturers.

First alert

Would Recommend

Easy to install, hard to change the battery. The battery should have ten-year life to avoid annual battery changes.
